Corsair RM1000x 1000 Watt 80 PLUS Gold Fully Modular Power Supply Review

Introduction & Packaging


Corsair have been known to produce some of the best power supplies in the business and today, they look set to continue that trend with the release of their high-end RM1000x. Not everyone needs 1000w of power, of course, but when you do, it’s likely that you’re also the kind of system builder who demands the best performance from your components. Previous high-end PSUs from Corsair have reaped some of the best results we’ve ever seen, with ripple so low we thought there was an issue with our testing equipment, so to say we’re a little eager to see what this one can do would be quite the understatement.

“Corsair RMx series power supplies give you extremely tight voltage control, quiet operation, Gold-certified efficiency, and a fully modular cable set. Built with all Japanese 105°C capacitors, they’re a great choice for high-performance PCs where reliability is essential. 80 PLUS Gold efficiency reduces operating cost and excess heat, and Zero RPM fan mode ensures virtual silence at low and medium loads. And, the fully modular DC cables make builds and upgrades easy, with clean, great-looking results.” – Corsair

Equipped with all the usual safety features you would expect, as well as 80 Plus Gold efficiency, all Japanese capacitors, a ZeroRPM mode, a powerful 135mm fan, fully modular cable design and more, the RM1000x certainly ticks all the right boxes and to sweeten the deal, Corsair has given it a 7-Year warranty! That last part fills me with a lot of confidence.

1000W is a lot of power, more than enough to power an extreme workstation or gaming system with enthusiast overclocks and multiple graphics cards. As you can see, that 12V rail can push a very mighty 83.3A, more than enough power for 

The packaging is very nicely designed, with a big and clear shot of the PSU on the front and that stand-out black and yellow Corsair branding.

Around the back, a quick technical rundown of the efficiency, hybrid fan mode and connectors.

There’s quite a lot of stuff in the box, with a durable protective bag for all the modular cables, a soft bag with the PSU inside, heavy-duty power cable,  cable ties, screws, and all the usual documentation.

SilverStone Strider Platinum ST55F-PT 550W Power Supply Review

Introduction & Packaging


Silverstone is one of the biggest PC component manufacturers in the world. Every year they launch a colossal amount of products that span a huge range of hardware and usage scenarios. They’ve got an ever-growing range of connectors, cables, fans, filters, I/O devices, chassis, coolers and more. Of course, the one that’s most important to us today is that they also make some of the industries best PSU hardware. Their new Strider Platinum ST55F-PT 550W really caught our interest, as not only does it pack 550W of power, it also has 80 Plus Platinum efficiency, fully module cables, high-quality components, and a hybrid/passive cooling feature, but it’s also incredibly compact for a PSU with these hardware specifications, making it a promising solution for compact system builds.

“As desktop computers continue to advance toward ever more efficient and smaller designs, SilverStone is helping to drive the efficiency movement by releasing the Strider Platinum series of power supplies. Created to be the smallest fully modular ATX power supplies with 80 PLUS Platinum efficiency, they are also incredibly quiet with the ability to run in fanless mode. If the loading condition is below 20%, the fan in the power supply can remain off for silent operation during idle or low powered computing activities. Other great features inherited from previous Strider series include ±3% regulation, powerful single +12V rail, 24/7 continuous power output, and multiple PCI-E cables. For those looking to build highly efficient systems in small footprints, the Strider Platinum is definitely the best choice.”

With a depth of just 140mm, this PSU should be extremely compatible with a very large selection of chassis products, including many of the very ergonomic chassis which Silverstone produce. With high-quality components that add excellent efficiency, voltage regulation and 24/7 operation, we have high expectation of what this PSU can do.

  • Compact design with a depth of 140mm for easy integration
  • High efficiency with 80 PLUS Platinum certification
  • 100% modular cables
  • 24/7 continuous power output with 40℃ operating temperature
  • Class-leading single +12V rail
  • Strict ±3% voltage regulation and low ripple & noise
  • Ultra silent 120mm fan with intelligent semi-fanless operation

All the usual security features are here, as well as a good range of connectors, a good quality fan and more. So let’s jump in and take a closer look at what it has to offer.

The packaging is nicely designed, with all the main hardware specifications detailed on the box, as well as the quote “world’s smallest 80 Plus Platinum full-modular ATX power supplies.”

Around the back, more technical performance data that most people are likely to ever read, but it’s nice that Silverstone are catering to those who understand it all.

In the box, you’ll find the mains power cable, some velcro cable ties, some plastic cable ties, the mounting screws, as well as an in-depth user manual.

Super Flower Leadex Platinum 550W Power Supply Review

With all that in mind, I’m very excited to see their latest unit, the Leadex Platinum 550W, in the eTeknix office today.

As the name would suggest, this is an 80 Plus Platinum rated unit, that means that the unit won’t be wasting as much of your electricity, or the money you spend on your electricity build, before it gets to your system, saving you a little extra money over the time you use it; certainly no bad thing being a little more economical and green.

Equipped with a fully modular design, all the latest safety features you would expect, high levels of efficiency, a premium quality semi-passive 135mm fan cooling design, and rather uniquely, a set of LED lights in the cable connectors, adding a little extra flair to your system build.

There’s not exactly a lot of extras in the box, just a few thumb screws and the owner’s manual, but you really don’t need much more anyway.

The cables come neatly packed away in a protective case, which is great for those who don’t need all the cables right now, but you may in the future when you upgrade and they’ll be neatly stored away.

Finally, you’ll also find the mains cable, which is nice and thick, making it durable, and comes with a good length.

Fractal Design Integra M 550W 80Plus Bronze Power Supply Review

Introduction & Packaging


Fractal Design has been making high-end PC components for years, having already made a respectable name for themselves in the chassis market, making good ground in the PSU market and in the last couple of years, they’ve also been doing interesting things with water cooling too. Today, we are of course more interested in their PSU business, as we have their new 550W Integra in for review, a 80Plus Bronze rated semi-modular unit that is targeted at mid-range systems within a reasonably affordable budget range.

“Fractal Design Integra M units are equipped with a large temperature-controlled 120mm fan for reduced noise levels and optimum cooling. The Integra M is a great choice for medium-performance gaming computers and workstations.” – Fractal Design

Equipped with a compact 140mm form factor, this ATX power supply is well suited to chassis that has a compact design, and that should allow you more room for cable routing, longer graphics cards, cooling and more, dependant on your chassis configuration. Modular and flat style cables are also a big win, as they’re much easier to route and you can remove any cables you do not require, helping you achieve a much cleaner looking system build.

The Integra M ticks all the usual boxes, as you would expect any modern power supply to; OPP, OVP, UVP and SCP. You’ll also find good quality Taiwanese capacitors, bronze efficiency, a good quality 120mm fan, and a trusty 3-year warranty.

The packaging is nicely designed, as is always the case with Fractal Design products. On the front, we can see prominently displayed, the three years warranty, 80 Plus Bronze rating and the 550W power output.

Around the back, a little technical information on the performance, although we’ll be testing this ourselves shortly, as well as information about the fixed and modular cables.

In the box, there’s a simple user guide, mounting screws, cable ties, a couple of velcro straps and the mains power cable.

Deep Cool DA500 Aurora 500W Power Supply Review

Introduction & Packaging


Deep Cool are one of the biggest names in the PC market, although perhaps not so much in Western markets, but that’s certainly something that has been changing. Deep Cool have launched a series of high-profile products over the last couple of years that you’ve no doubt seen. From their funky Steam Castle chassis to their Lucifer CPU coolers, there are a lot of nice products out there and that gives me high hopes for their new DA500 power supply.

“DA 500 is certified with 80 plus bronze with up to 85% electrical efficiency enabling lower heat generation and lower operation cost. Outstanding and stable performance makes it one of the ideal choices for multi-purpose usage. Double layer EMI filters protect from magnetic interference and restrains noise while operating.”

This unit is designed to be a little budget-friendly, so I’m not expecting earth-shattering performance, but I am expecting it to be a strong contender in its respective price bracket. Not everyone can afford nor requires high-end hardware, but the mid-budget market is fiercely competitive, so it’ll be fun to see how Deep Cool can compete.

  • Compliant Intel ATX12V v 2.31
  • The integrated Active PFC+ PWM Combo Controller will increase the efficiency of exchange and make PFC higher than 99%
  • 80 PLUS® Bronze certified — up to 85% efficiency
  • Assembled copper + AL heatsink make cooling more efficient
  • 120mm silent fan with PWM function
  • The longer cable design supports cable management perfectly
  • Double-Layer EMI Filter protects from electromagnetic interference & restrains noise
  • Intelligentized eco-friendly chipset, consume < 1W in its off-mode, compliant Erp standard
  • CircuitShield —OVP, UVP, SCP, OPP
  • Supports Multi-Way SLI / CrossFire + Multi-Core CPUs

The packaging is pretty standard, with a nice run down of the major features and spec right on the front. The most notable things here are the 80 Plus Bronze efficiency, 100,000h MTBF and that promising 3-year warranty.

Chieftec SFX 500GD-C 500w Power Supply Review

Introduction & Packaging


Compact systems are becoming increasingly popular, with many chassis now being so small, that they no longer support the common ATX PSU standard. This is where smaller form factor power supplies, such as the Chieftec SFX 500GD-C we have on the test bench today, come into play. The smaller form factor makes them perfect for compact system builds and with 500W of power on offer, this tiny PSU still has more than enough juice to power a decent gaming system, making it a prime choice for those building a small LAN gaming system, HTPC style gaming system, or even just those who have limited room for a desktop rig/workstation.

In terms of hardware, the GD-C ticks all the right boxes, with a powerful 40A +12V rail, modular cables for easy installation and cable management, 80 Plus Gold efficiency and all the safety features we have come to expect from a modern unit. Of course, the real big, or should I say little, feature is that it’s all housed in a tiny little unit.

Packaging & Accessories

The box is nothing too fancy, but it does have a nice image of the PSU on the front, which shows off the modular cable design.

There’s very little in the box, so little that you’ll only find a user manual beside the PSU and modular cables. Annoyingly, there wasn’t even an AC mains cable. Fortunately, we have a few of those lying around, so that’s no going to cause issues with our testing.

Enermax MAXPRO 500w Power Supply Review

Introduction


Enermax makes some of the best PSUs money can buy, that much is no secret. Only recently we reviewed the Enermax DIGIFANLESS 550W PSU and we honestly think it’s one of the best power supplies we’ve ever tested! It set the bar pretty high and while the unit we’re testing today is a little further down the price ranges, I’m still eager to see if it delivers the same uncompromising performance we’ve seen from Enermax products in the past.

The MAXPRO is designed to be a little more cost-effective, so it strips away the premium packaging, there are no modular cables and it only offers standard 80 Plus efficiency, which doesn’t sound that great, but from what we’ve been told, it makes up for this with rock solid build quality and great performance. Designed for demanding systems, the MAXPRO will run stable & safe 24/7 @ 40c operation, which is certainly better than most. IT comes with all the safety regulations you could hope for, a high-quality 12cm fan for virtually silent operation, it’s Haswell ready and much more.

As I said before, the packaging is pretty basic, but at the end of the day, a box is just a box and that’s a little extra cost saving for the consumer.

In the box, you’ll find the mains adaptor, a simple user’s manual and some mounting screws; not much, but it’s literally all you’re going to need.

Antec Strictly Power VPF550 Power Supply Review

Introduction & Packaging


Antec produce some of the most popular PSUs on the market, their PGS series has been a popular choice for many years now and their more recent EDGE series are winning people over too.

This is a low to midrange power supply, offering 80 Plus Bronze efficiency, 550W of power, non-modular cables and a very affordable £40 price tag. Sure it’s not that exciting, but a budget-friendly gaming system or office computer will no doubt be an ideal target for Antec’s latest.

The packaging is nicely designed, showing all the main specifications right on the front, including the support for Haswell, active PFC and continuous power.

The same details are on the back of the box, as well as the multi-language breakdown.

In the box, you’ll find some warranty information, four mounting screws and the AC power cable.

The unit comes well equipped with high-end features, which means I’m expecting nothing short of excellent performance from it. It promises high-end thrills and performance, so that’s exactly what it has to deliver in our tests. So let’s stop beating around the bush and take a closer look at what this unit has to offer, before firing it up on our load tester.

The packaging is very nicely designed, with a clear image of the PSU on the front, as well as a quick run down of the main specifications.

Around the back, a more detailed explination of the general design, such as the SolidLink Connectors that keep the interior of the PSU neat and tidy; this helps greatly with airflow and cooling.

In the box, you’ll find the usual power cable, some mounting screws and the user manual.

Corsair HX750i Fully Modular Platinum Power Supply Review

Introduction & Packaging


Corsair is one of the most recognisable brand names in the PC market. They’ve huge a vast range of chassis, peripherals, storage, memory, power supplies and more! As well as years of history with consumers and a fiercely loyal fan base that has served them pretty well too. Their power supplies are some of the most popular around, especially their budget friendly models, which have been a prime choice with system builders around the world.

Today, we’ll be taking a look at their HX750i, a high-end 80 Plus Platinum rated unit that will be well suited to powerful single GPU systems and even some dual-GPU systems. The extremely efficient power delivery is certainly appealing, but will come at a premium, but you’ll also find Corsair Link, fully modular cables, a Zero RPM fan mode, a 7-year warranty and more, so Corsair is certainly doing a lot to tempt you to invest in a high-end unit.

“HXi Series power supplies give you extremely tight voltage control, virtually silent operation, and a fully modular cable set. With all Japanese 105°C capacitors, they’re a great choice for high performance PCs where reliability is essential. 80 PLUS Platinum efficiency reduces operating cost and excess heat, and together with Zero RPM Fan Mode technology, gives you virtually silent operation.” Corsair

In the box, you’ll find a large and durable component bag, which houses all of the cables for the PSU. This is handy for storing any you’re not using, should you need them in the future.

You’ll also find a user manual, warranty guide, an AC power cable, a few cable ties and the PSU mounting screws; everything you’re likely to need to get set up.

Antec HCP Platinum Continuous Power 1000W Power Supply Review

Introduction & Packaging


Antec have produced some extremely popular power supplies over the years, such as their very reliable PGS series, many of which I’ve owned and used myself over the years. For those with demanding systems, such as test benches, rendering systems and gaming rigs, their HCP Continuous Power units are a popular choice, so we’ve been eager to get one onto our test bench and see how good they really are!

The unit we have today is rated for 1000W with an 80 Plus Platinum efficiency, so there’s no doubt that this is a high-end/enthusiast unit, and that means it’s going to be something worth considering for those building a multi-GPU system thanks for the high power output and the potential long-term savings due to the high levels of efficiency. Of course, we’re also hoping to see stable power output and a whole lot more, so let’s take a closer look at what it has to offer.

“Antec’s High Current Pro Platinum series is the pinnacle of power supplies. High Current Pro Platinum is fully modular with a revolutionary 20+8-pin MBU socket for the needs of tomorrow. By using a PSU that is 80 PLUS® PLATINUM & ErP Lot 6: 2013 certified, operating up to 94% efficient, you can reduce your electricity bill by up to 25% when compared to many other power supplies.

Backed by a 7 year warranty and lifetime global 24/7 support, the HCP-1000 Platinum embodies everything a power supply can accomplish today.” – Antec

The unit comes with 4 high current +12V rails, a little old school, but balancing your per-rail load is not rocket science for any enthusiast. All the usual protection features are present and accounted for as well as 16-pin modular sockets.

In the box, you’ll find some documentation, a few velcro cable ties and screws, as well as the mains power cable.

There’s also a handy storage bag, which houses all of the included modular cables.

XFX XTR 550 Fully Modular Power Supply Review

Introduction


One of the latest XFX power supplies is on our test bench today, bringing 550W of power as well as 80 Plus Gold efficiency to your system, making it a solid contender for most mid-to-high end gaming PC’s. Many people think they need 1000W plus from their PSU, but that simply isn’t the case, with most high-end single GPU systems rarely drawing more than 400-500W from the wall. Being a Seasonic manufactured unit, I’m expecting great things from the XFX XTR Series 550W PSU.

 “Designed for serious gamers and DIY professionals, the XFX XTR Series 550W Full Modular 80 Plus Gold power supply delivers the clean and stable power required for demanding gaming rigs and workstations. A single strong 12V rail flexibly routes the maximum available power to the parts, enabling you to maximize power usage and making setup easy. It’s also been awarded the 80Plus Gold certification for its high power efficiency, and is also designed for NVIDIA SLI and AMD Crossfire multi-GPU systems, making it a perfect solution for hardcore gamers. Its modular design reduces cable clutter. And the large fan delivers silent cooling, so your computer and PSU can operate at peak performance.”

Equipped with a powerful single +12V rail configuration, modular cables, CrossFire/SLI compatibility, Haswell support and much more, this is certainly a capable unit for a wide range of systems. Of course, you’ll also find it comes equipped with all the latest safety features, as well as high-quality Japanese capacitors, which should allow for clean and stable power delivery.

As with many Seasonic manufactured units, this PSU also comes equipped with a Hybrid Fan, allowing you to switch between always on cooling and a semi-passive mode, perfect for those who desire maximum performance or silent operation.

  • EasyRail Plus Technology allowing plenty of wattage headroom to handle your devices
  • Hybrid Fan Control allowing the power supply to operate silenty until it reaches 20% load or 25C
  • Ultra Quiet Fan Design
  • Ultra Voltage Regulation Design
  • Haswell Ready

  • True Wattage guarantee
  • 80 Plus Gold certifying 90% power efficiency
  • Extreme heat tested capacitors

The packaging is very nicely designed, with some stylish images on the box as well as a rundown of the major features, such as Haswell Ready, Japanese Caps, SLI/CrossFire and 80 Plus Gold efficiency.

Another important feature on the back, the True Wattage Guarantee, always a reassuring thing to see and something we’ll certainly hope to see in our test results.

In the box, you’ll find a durable power cable, some mounting screws and a user manual, nothing too fancy, but it’s everything you’re going to need.

Cooler Master V750 Modular Power Supply Review

Introduction


Cooler Master is one of most recognisable and well-respected names in the PC component market. Over the years, Cooler Master has created some of the best power supplies, coolers and chassis around, not forgetting their gaming division CM Storm, which has delivered some very impressive headsets, keyboards, mice and much more too! With all that in mind, I am very excited to see another Cooler Master product in the office today, their brand new V750 power supply, which promises premium performance in a tidy and compact form factor.

“V Series power supplies feature the most stable and efficient power supply unit in its class thanks to exclusive 3D circuit design and Silencio FP technology. The V Series has fully modular flat cables with energy-saving 80PLUS Gold/Platinum ratings all delivered in a compact design smaller than most Power Supply Units (PSUs) in its class. The V series family is available in V550, V650, V750, V850, V1000 and V1200 watt variants perfect for gamers, enthusiasts and even system builders.” – Cooler Master

The V750 uses a unique 3D circuit design, Cooler Master’s own Silencio FP fan technology, fully modular flat cables, 100% Japanese capacitors and much more. The overall quality is reflected in the fact that this tidy, 150 x 140 x 86, form factor still delivers 750W of power at an 80 Plus Gold efficiency

There are three models available, the 550W, 650W and the 750W. We have the 750W at our disposal today, but all models come with 100-240Vac, good active PFC, >100,000 hours MTBF and are backed up by a reassuring 5-year warranty.

The box is very similar to previous Cooler Master designs and features a nice picture of the PSU, as well as a quick run down of the major features; 750W, Japanese Capacitors, 5-year warranty, Silencio fan and 80 Plus Gold.

Around the back, a run-down of the included cables and performance, but we’ll take a closer look at those ourselves in a moment.

In the box, you’ll find a nice cable storage bag, a collection of cable ties, four mounting screws and the mains adaptor.

 

Cooler Master G750M Semi-Modular Power Supply Review

Introduction & Packaging


Cooler Master is one of the most recognisable brands in the PC component market. They’ve got a huge range of massively successful products, ranging from the CM Storm peripherals to their widely popular chassis and, of course, their power supplies. Cooler Master have created some stunning high-end PSU products over the years, but today we’ll be looking at something a little more modest. Their new G750M is a semi-modular design and comes with a pretty basic and what I would like to call beginner friendly configuration. This isn’t really going to be used for multi-GPU gaming systems, but should still offer plenty of grunt for single GPU gaming systems or desktop/office computers. It’s also modestly priced, offering a competitive and trusted brand name for those that need a good level of power and efficiency, without spending mega-bucks for it.

All the usual protection features are present, including the ever so important OVP and OPP. There’s a full-range input voltage, standard ATX form factor and it’ll output up to 750W, so it’s certainly got a broad appeal for a wide range of systems.

The box is pretty standard, with a nice image of the PSU on the front, as well as a quick run-down of the major features. The most important things there are 80 Plus Bronze efficiency, the single 12V rail and the 5-year warranty.

Around the back a little bit of technical information, but since we’re here to test this unit, we’ll be providing you with our own figures.

In the box, you’ll find a user’s manual, four mounting screws and the mains power cable.

be quiet! Dark Power Pro 11 550W Power Supply Review

Introduction & Packaging


It’s no secret that be quiet! make some of the best PSUs money can buy, we’ve seen time after time that they can deliver great looking and performing products. A few months ago, we took a look at one of their latest and greatest units, the Dark Power Pro 11 1200W PSU and it was certainly impressive, offering excellent power delivery, whisper quiet performance and gorgeous aesthetics, but what if you don’t need huge amounts of power for your system, but you still want a very high-quality unit? That’s where the new Dark Power Pro 11 low-wattage models come into play.

“The Dark Power Pro 11 is the most advanced high-end power supply from be quiet!. Massive power, Overclocking Key, which can switch between quad and single-rail operation, an almost inaudible performance due to a be quiet! SilentWings 3 fan and – for us – the highest efficiency certification in the form of 80PLUS Platinum are some of the features of the new Dark Power Pro-models.” – be quiet!

At our disposal today, we have the Dark Power Pro 11 550w, offering more than enough power for a single-GPU system, workstation, office system or HTPC. Don’t think lower wattage means less features though, as you’ll still find 80 Plus Platinum efficiency, semi-modular cables and premium grade build-quality throughout.

Packaging and accessories

The box is nicely designed and features the typical black design we see on all be quiet! products. What is interesting is seeing the “high-end” branded together with 550W, as lower wattage units are rarely high-end.

Around the back, a quick run-down of all the included cables and features, but we will, of course, take a much closer look at these in a moment.

In the box, you’ll find the AC power cable, user manual, OC key, fan cables and a collection of cable ties. The OC key is a nice touch, as it can be mounted in a space PCI-e expansion slot, giving you a physical switch for toggling between single and multiple rails on the PSU; not everyone will need such a thing, but it’s nice to have. The other welcome addition is the fan extension cables, as the PSU can have fans connected directly to it.

Seasonic Platinum 1050W Modular Power Supply Review

Introduction & Packaging


Seasonic is one of the most respected PSU manufacturers in the world, not only do they create their own premium grade units, but they’re also one of the most popular manufacturers used by a range of PSU brands around the world. Time and time again we’ve seen them deliver flawless designs, incredible performance and a whole lot more, so we’re very excited to have one of their latest and greatest units on our test bench today.

The Seasonic 1050W packs a huge amount of power, making it an ideal choice for overclockers and those with multiple graphics cards in their systems. It comes with premium grade components throughout and this helps it operate at 80 Plus Platinum efficiency, meaning it’ll cost you less on your electricity bill to run vs Gold, Bronze and below rated PSU units.

Packed with features such as Ultra Stable Voltage, a Hybrid Silent Fan Control which allows for 0RPM operation at low loads and Dual Copper Bars, the 1050W Platinum sounds like a premium choice for system builders.

As you can see, the 1050W hits all the usual requirements of a modern PSU, can operate between 100-240v AC and features all the protection features you would expect.

The packaging is nicely designed, keeping in theme with the rest of the Seasonic range.

Around the back, a quick run down of what 80 Plus Platinum efficiency is, as well as a run down of the major features; which we’ll take a look at in a moment.

In the box, you’ll find a durable storage bag that houses all the modular PSU cables and the 3-pin power cable.

There’s also an assortment of plastic and velcro cable ties to aid with cable management, an owners manual and with this unit, a UK 3-pin power cable.

Enermax DIGIFANLESS 550W Power Supply Review

Introduction & Packaging


The latest Enermax power supply landed in the eTeknix officer recently and while I admit, it can sometimes be difficult to get excited about a power supply, I am very much so about this one. The DIGIFANLESS packs two important features, as the name would suggest; it’s fanless and it is digital. Fanless power supplies are an incredible addition to your system, especially if you’re trying to build a completely silent rig, as the removal of the fan means you’ll never hear a single noise from the unit and that’s certainly no bad thing!

Despite being passively cooled, the DIGIFANLESS still promises to churn out two very impressive figures. The first is that it’ll run up to 550W, which is more than enough for a single GPU system and a powerful CPU. The second is that it will deliver 80 Plus Platinum rated levels of efficiency. Let’s just recap, digital monitoring, passive cooled silent performance, 80 Plus Platinum, 550W of power and if that’s not enough to open your eyes wide, he’s the classic “but that’s not all” sales pitch. It also has fully modular, has individually braided premium grade cables, all Japanese capacitors, is rated to run 24/7 and comes with a 5-year warranty! Enough dancing around, let’s jump right in and take a closer look!

The packaging is really nicely designed, giving a good rundown of the specifications and I’m already getting a nice “premium” vibe here.

Around the back, a nice run down of all the cables, the digi features, the high-quality capacitors and more.

Normally the packaging isn’t something I talk about too much, but the DIGIFANLESS was so well packaged, I just had to take a quick picture.

In the box, you’ll find the mains power cable, the digital link cable, the owner’s manual and a protective storage bag.

SilverStone SX600-G SFX Series Power Supply Review

Introduction & Packaging


Silverstone is well-known for their high-end products, having created some very impressive power supplies, coolers, chassis products and a whole lot more over the years. One of their strongest areas is certainly in the power supply market, even more so when you look at smaller form factor units such as SFX. The benefits of SFX units are obvious, as they’re much smaller than ATX PSUs, which makes them great for slim and compact chassis designs, such as the RVZ01 which Silverstone produces. These slim chassis are often designed for compact workstations, or HTPC use and more recently “Steam Machine” style rigs. Squeezing a massive graphics card into a compact chassis isn’t impossible, but powering a monster GPU is not so easily accomplished with a tiny power supply and that’s where the new SX600-G comes into play.

The SX600-G packs an impressive range of features, such as 600W 80 Plus Gold Efficiency power delivery, more than enough for even the most powerful graphics cards on the market today, with some power headroom for overclocking of your CPU and GPU alike. In true TV infomercial style “but that’s not all”, this unit also features an intelligent semi-fanless design, allowing for zero RPM operation in low load or cooler environments, 100% modular cables, a powerful single 12V+ rail, and dual PCI-E 8/6-pin connectors; in short, this unit almost sounds too good to be true.

The packaging is nicely designed, with lots of bright colours and a good photo of the product, as well as a quick run down of the main specifications.

All the technical stuff is around the back of the box, not much interest to most consumers, but in short the PSU promises to be efficient and provide stable power output; pretty much what any PSU should do really.

In the box, you’ll find a few bits of documentation, an SFX to ATX adaptor bracket, some mounting screws and the AC power cable.

SuperFlower Leadex Platinum 750W & Titanium 1000W Power Supply Review

Introduction & Packaging


SuperFlower is one of the leading names in the PSU market, with a wide range of products that cater to a wide range of budgets, although their specialty certainly seems to be in the high-end market, where they offer an impressive range, both in terms of aesthetics and performance for the enthusiast and prosumer markets. Today, I’ll be taking a look at not one, but two of the latest SuperFlower power supplies; the Platinum rated 750W and the Titanium rated 1000W.

Platinum and Titanium rated efficiencies are both very impressive, especially given that many consumers rarely shop above 80Plus Gold. The end result from these higher ratings is that the PSUs should be extremely efficient and could potentially save you some money on your electricity bill in the long run; which is no bad thing. This isn’t a head-to-head “which is best” review, as they’re both spec’d to have their own strength, one for the usual high-end user, the other is aimed a little more at the enthusiast side, so it’ll be interesting to see if spending that bit extra is really worth it overall.

Packaging and Contents – Leadex Platinum 750W

First up we have the 750W Platinum, which comes nicely packaged in a rather eye-catching box.

Around the back, we have a quick run down of all the major features; we’ll take a closer look at those in a moment.

In the box, you’ll find all the usual bits first; power cable, owners manual and some chassis mounting screws.

Corsair RMi Series RM1000i Fully-Modular Power Supply Review

Introduction & Packaging


The latest range of Corsair PSUs are here at last! The new RMi series is something of an upgrade, offering higher quality components, higher performance and more features compared to the last generation; pretty much everything you would expect from the latest range of anything tech related. Corsair has a rock solid reputation in the system building market, delivering popular and competitive products from CPU coolers, chassis, power supplies and more, so we’re hoping to see them put up a good fight on our test bench today.

The RMi series has a lot in common with the current RM series PSU units, as it still offers all the high-end features you would expect; 80 Plus Gold Certification, fully modular cables, Zero RPM fan modes (up to 40% load), silent component selection (reduced coil whine) and LLC resonant mode topology w/ DC to DC (improves efficiency and voltage regulation). However, the RMi series is setting the bar even higher, with a 7 year warranty, all Japanese capacitors, full output at 50c, a fluid dynamic bearing fan, digital output for additional Corsair Link monitoring capabilities, as well as additional Corsair Link control capabilities, which includes custom fan profiles and the ability to toggle the +12v rail from multiple to single rail modes.

“Corsair RMi Series power supplies are fully modular and optimized for silence and power efficiency. Zero RPM Fan Mode means that the fan doesn’t spin until the power supply is under heavy load, and the fan itself is custom-designed for low noise operation even at high loads. 80 PLUS Gold rated efficiency saves you money on your power bill, and the flat black cables are fully modular so you can enjoy fast, neat builds. The Corsair RMi Series is built with high-quality components, including all Japanese electrolytic capacitors, and is guaranteed to deliver clean, stable, continuous power, even at ambient temperatures as high as 50°C. Users can also install Corsairs Link software to monitor power usage and fan speed. With 650W, 750W, 850W and 1000W models available there is a Corsair RMi power supply suitable for potentially any PC configuration.” – Corsair

Packaging and Contents

The RM1000i offers up, you guessed it, 1000 watts of power. There’s a nice and clear image of the PSU on the front of the box, as well as a quick run-down of the major features on the rest of the packaging, such as the 80 Plus Gold certification and semi-passive cooling design.

In the box, you’ll find the manual, warranty guide, power cable, screws and a few cable ties to help you keep everything neat and tidy.

Corsair RMi Series RM650i Fully-Modular Power Supply Review

Introduction & Packaging


Corsair is one of the biggest names in the industry, covering a wide range of products from chassis, peripherals, cooling, audio and more importantly today, power supplies. Their latest range of PSUs promises to deliver some impressive performance figures and we’ve got two of their new RMi series products on our test bench and ready to rock. First up, we have the 650 watt unit, which to some may not sound like a lot of power, but from my experience, few systems pull more than 500 watts even at full load, so there’s no doubt in my mind that this unit is the one aimed at mid to high-end gaming systems and day-to-day users.

The RMi series is a big improvement on the current RM series of PSUs. They still offer the high-end features of the previous generation, such as 80 Plus Gold Certification, modular cables and more. With the added bonus of a 7-year warranty, full Japanese capacitors, a fluid dynamic bearing fans, digital output (Corsair Link), custom fan profiles and something for the enthusiast crowd, the ability to switch the +12v rail between multiple and single rail modes.

“Corsair RMi Series power supplies are fully modular and optimized for silence and power efficiency. Zero RPM Fan Mode means that the fan doesn’t spin until the power supply is under heavy load, and the fan itself is custom-designed for low noise operation even at high loads. 80 PLUS Gold rated efficiency saves you money on your power bill, and the flat black cables are fully modular so you can enjoy fast, neat builds.

Packaging and Contents

The packaging is nicely designed, with a clear image of the PSU on the front of the box, as well as detailing the 7-year warranty and 80 Plus Gold certification.

In the box, you’ll find a power cable, some cable ties and mounting screws, the warranty guide and user manual. There was also a USB drive included, but at this time we think this may only be for press, not for consumers, as it contained information about the testing in-house of the power supply.

be quiet! Dark Power Pro 11 1200W Power Supply Review

Introduction & Packaging


be quiet! are regarded as one of the best brands in the business, from their high-end CPU coolers, system fans and of course their power supplies, many of which are regarded as some of the coolest, quietest and best make products available today. Obviously, the quiet part is a given, with a name like be quiet!, if they made noisy products, it would be quite a disappointment. To achieve quiet performance, be quiet! uses high-quality components, premium grade build quality and design, so it’s no surprise that they’ve won many awards in the past; will we see a repeat performance today?

The Dark Power Pro 11 is the latest entry in their popular Dark Power Pro series. There are a few notable features to this power supply that make it stand out from the competition. First we’ve got the new SilentWings 3 135mm fan which features the new 6-pole motor, a redesigned bearing, the lowest startup rotational speed in the market (under 250FPM) and more; promising virtually inaudible performance and improved cooling. Of course, power delivery is improved too, with high-quality PFC capacitors, higher efficiency, improved voltage stability, regulation and more!

Packaging and Contents

As you can see, the be quiet! Dark Power Pro 11 comes in the usual packaging design of any other be quiet! product. Down the left side of the box, it’s marked “high-end”, although the words “80 Plus Platinum” and “1200w” are also strong indicators that this is a high-end/enthusiast focused product.

The Dark Power Pro 11 is semi-modular and comes with a hard-wired 24-pin, not big deal since literally all systems will need this cable and making it modular would only add to the cost. There are two CPU power cables, an 8-pin and a 4+4, Four SATA/Molex cables with FDD options. One of the more important cables, there are four PCIe cables, three with dual 6+2 connectors and a single 6pin PCIe cable. Finally, you’ll also find external fan connector cables, more on those in a moment, and the Overclocking Key add-on.

In the box, we found two power cables, one for EU and one for UK, although we expect this will differ based on region.

Included extras from left to right, are the fan adaptor cables, OC jumper, Overclocking Key switch, screws, cable ties, thumb screws and two Velcro cable ties.

Thermaltake London 550W Semi-Modular Power Supply Review

Introduction & Packaging


Naming power supplies after cities of the world is certainly a unique strategy to grab the attention of buyers in an otherwise saturated power supply market: Thermaltake have opted for “Berlin” and “London” name-tags on some of their power supply series. On paper, at least, the Thermaltake London 550W power supply that we are reviewing today does appear to be a new product even though it falls under the existing Toughpower series.

At first glance the similarities between the Thermaltake London 550W and Toughpower Gold 550W seem strong as they are both 80 Plus Gold rated 550W power supplies boasting 5 year warranties and active PFC. But comparing their specifications we see the London 550W PSU features a semi modular design, quieter fan and an increased MTBF over the Toughpower Gold 550W – all of which are improvements. On the negative side the London 550W features a shorter hold up time of 12ms which actually falls below the minimum 16ms allowed by the ATX specification: the Toughpower 550W Gold offered 17ms. The London unit is also slightly bigger featuring an extra 20mm of depth which is what allows it to run a bit cooler and quieter as a 140mm fan can be used instead of a 120mm on the older Toughpower Gold.

Packaging and Contents

The London naming also plays into the branding with a picture of London’s iconic Tower Bridge gracing the box and the power supply unit.

Around the rear, quite ironically, we see that the box’s writing is in German. Maybe they sell the Thermaltake Berlin power supply in English to balance it out?

The accessory package is nothing out of the ordinary with a user manual, warranty guide, power chord, some screws for securing the PSU into your case and a rather stingy 4 zip ties for cable management.

Corsair HX1000i Modular Power Supply Review

Introduction & Packaging


Corsair’s power supply portfolio seems to be constantly evolving with major updates coming all the time as Corsair learn from previous product releases and customer feedback. In late 2013 we saw the introduction of the RM series which was Corsair’s newest range of Gold rated power supplies with all the bells and whistles of a high-end PSU like a fully modular design with black cables, Corsair Link support and a semi-passive fan mode. The Corsair HX1000i that we have with us here today is the second largest wattage of the new HXi series of power supplies. The HXi series builds on the RM series platform in many ways. Channel Well Technology are the OEM producer of both series platforms and the HX1000i is an enhanced version of the RM platform as it features better efficiency, more sophisticated ripple suppression capabilities and extra bells and whistles such as digital monitoring and controls of the rail mode and fan speed. These digital controls are what give this product the “i” moniker that set it apart from previous HX series Corsair power supplies, but it is important to note the HXi series does not have digital circuits like the AXi series has. The HXi series should be thought of as partially-digital whereas the AXi series is fully digital.

With 1000W of continous power Corsair are targeting this particular unit at multi-GPU system owners who need something with proven quality. The HX1000i comes backed with a 7 year warranty as well as being rated for continuous stable power delivery at 50 degrees celsius. That stability under high temperatures is one of the main reasons Corsair are able to deploy a semi-passive fan mode on this unit with an extremely tame fan profile when the fan does finally need to turn on. The HX 1000i seems to be the ultimate power supply to have before making the step up to Corsair’s AXi series which features even more advanced digital controls of voltages and ripple suppression. Strangely Corsair do not offer an AX1000i unit so the HX1000i has no direct competitor, the closest model is arguably the AX1200i.

Packaging and Contents

The HX1000i comes packed in a substantially sized box. The main reason for the large package is that the power supply unit is quite large but also because Corsair include a significant selection of cables to cater to just about every possible use-case scenario of 1000 watts.

The accessory package includes a variety of documentation, black zip-ties, a Corsair case badge, black case screws and a power chord.
