Corsair Announced New HX1200i Platinum Rated PSU

Corsair announced the latest addition to their award winning HXi series, this time in form of the HX1200i. The new power supply delivers 1200 watts of platinum rated power in a fully modular design.

The PSU is able to drive even demanding three and four card Nvidia SLI or AMD CrossFire multi-GPU systems with the 92% or better energy efficiency. The fluid bearing FAN has a zero RPM mode so it won’t spin unless it is needed. Futher the user can customize the fan profiles and monitor the voltages through the Corsair Link software.

The all around flat cables allow you to route the cables even better and prevent unnecessary airflow problems. There are plenty of connection options to take advantage of the 1200 watts of power: one 20+4 pin ATX, two 4+4 pin EPS, twelve 4-pin Molex, twelve SATA and eight 6+2 pin PCIe connectors, as well as two Berg/Floppy.


  • 1200 watts
  • 80 PLUS Platinum efficiency
  • Fully modular DC cable set
  • 100% Japanese electrolytic capacitors rated at 105°c
  • Zero-RPM fan mode for virtually silent operation at low and medium loads
  • Corsair Link support for monitoring efficiency, voltages, power output, temperature, and fan speed plus user customizable setting of rail modes and fan speed.
  • Fluid dynamic bearing fan

Seasonic Announces Snow White 1050 Watts Hybrid PSU

Seasonic has announced what must be the PSU of the season, a snow white PSU dubbed the Snow Silent-1050 (SS-1050XP Active PFC) that as the name suggests is a 1050 watts power supply. The new PSU is 80 Plus Platinum certified and fully modular as well as hybrid-treated for the fan.

Not only does the Snow Silent feature a hybrid fan setup that completely turns itself off when the device is cold enough, but it also has the option to disable this feature and just run it normally with the fan spinning all the time. The single +12V rail design should ensure equal performance of all connected devices.

The Snow Silent features plenty of connectivity and support for up to four graphics cards. The total connection count is one 24-pin ATX, one 8-pin and one 4+4-pin EPS, eight 6+2-pin PCI-Express, fourteen SATA, five Molex and one Berg/floppy connector. No word on pricing or availability yet, but it sure looks great.

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.

Cooler Master V1200 Platinum 1200W Modular Power Supply Review

Introduction & Packaging

Developing a power supply with a wattage as high as 1200W involves a lot of technical expertise; this is why you’ll find the number of OEMs producing power supplies at this wattage level is lower than in the sub 750W market. The market for 1200W power supplies is significantly smaller too with only a handful of desktop PC users needing this much wattage. Furthermore, the build quality and standards of high-wattage power supplies tend to be higher so users in this market segment will upgrade less: especially when 5, 7 and 10 year warranties are becoming the norm.

Cooler Master know all of the aforementioned things which is why they teamed up with veteran power supply vendor Seasonic to produce their Platinum series V1200 unit. On paper this unit is as good as it gets with 80 Plus Platinum efficiency certification, a semi-passive fan operation mode, high quality Japanese capacitors, a fully modular design and a 7 year warranty. In terms of hardware support Cooler Master offer a staggering 12 PCIe connectors and dual EPS 8 pin connectors allowing you to easily run quad GPU systems or even dual CPU socket based motherboards such as the Haswell-EP Xeon platform from Intel.

Packaging and Contents

Cooler Master’s packaging hasn’t changed much over the years and it still sports the plum and black colour scheme with some embossed silver details to accentuate the premium nature of this product.

Around the back of the main box we find specifications, pictures and details about the Hybrid fan technology and efficiency curve. Cooler Master claim significant savings on power bills over 80 Plus Gold and Bronze units but their numbers include a fairly unrealistic use-case scenario of a 1000W system running at 100% load 24 hours a day.

The accessory bundle includes a user’s manual, four black screws. some cable ties, a UK power chord and a PCI bracket which controls the fan between auto and Hybrid mode. The idea with this PCI bracket is to mount it at the back of your case in one of the PCI slot covers so you can easily change the PSU fan operation mode., if desired.

Fractal Design Newton R3 1000W Semi-Modular Power Supply Review

Introduction & Packaging

Fractal Design kicked off its brand by making a single type of product: computer cases. However, like many other computer hardware brands Fractal Design made the decision to expand its product portfolio to encompass other things. One of Fractal Design’s new product areas is power supplies and just like with their cases Fractal Design were adamant about making sure they reach the same high level of quality their brand is renowned for. On the topic of high quality it is time for the Newton R3 1000W power supply to enter.

Fractal Design have pulled out all the stops with this new power supply model which features high quality 80 Plus Platinum capable internals, a modular design and a glossy white or black finish to match their computer cases. Fractal Design are also renowned for producing quiet cases; they were one of the first brands to mainstream the use of noise-dampening foam inside cases. Consequently it shouldn’t surprise you that the Newton R3 1000W power supply offers a hybrid fan mode that doesn’t spin up until the fan is needed. Even when the fan does spin up Fractal Design are claiming very low noise output as well as enhanced reliability for a ball-bearing based fan design. Other noteworthy selling points include the use of Japanese capacitors in this power supply’s construction and an impressive 5 year warranty.

Packaging and Contents

The Newton R3 comes in one of the largest retail packages I have ever seen. The packaging uses a sleeve over a plain white box with a carry handle.

The accessories are modest but are exactly what are required: a power cable, users manual, cable ties and some screws.

Silverstone Nightjar 520W Passive Modular Power Supply Review

Introduction & Packaging

One thing that you learn reviewing power supplies is just how big Seasonic are. Seasonic platforms are used by multiple brands due to their exceptional quality, performance and reliability. Silverstone are one of those brands that use Seasonic platforms. In a case of déjà vu I am looking at another Seasonic Platinum rated 520 watt passive power supply. Firstly, I took a look at the XFX XTS 520, then Seasonic’s own Platinum 520 and now Silverstone’s Nightjar 520. The internals are identical to the aforementioned PSUs: we’ve still got 80 Plus Platinum efficiency, Seasonic’s promised +-2% voltage regulation, active PFC and a fully modular design. The best part is of course the passive operation and the “Nightjar” moniker of this Silverstone power supply is supposed to reflect that passive segmentation. To aid with the passive operation the Platinum efficiency is vital for minimising heat but the well ventilated enclosure is also important.

An extensive recap of this unit’s specifications can be found below:

Packaging and Contents

White/silver seems to be the theme of this product as they are the closest to the colour of Platinum. The front of the packaging clearly orchestrates that passive operation is the flagship feature of this product.

Around the back we find Silverstone championing the quality and features of this product; assisted mainly by the Seasonic OEM platform used.

Included with the Nightjar 520 is a power cable, selection of documentation, velcro cable ties, standard cable ties and four silver screws for mounting to your case.

Seasonic Platinum Fanless 520W Modular Power Supply Review

Introduction & Packaging

Fanless power supplies have become increasingly popular over the past few years as the efficiency of power supplies has risen, meaning they produce less heat, and the efficiency of computer components has increased, meaning they consume less power. The convergence of these two trends makes it possible to run a high end system with a passive power supply. In fact, with the Seasonic Fanless Platinum 520W power supply we have here today it is possible to run a Core i7 4960X based system with an Nvidia GTX Titan Black and still have plenty of capacity left over for other things.

To our regular readers this power supply may look identical to another power supply we reviewed recently; the XFX XTS 520. There’s a reason for that – they are the same units internally. As many of you may known Seasonic produce a lot of power supplies and if they don’t sell them under the Seasonic brand, they sell them to other vendors who resell them, such as XFX, Antec and many more.

Below you can find the full specifications of Seasonic’s Platinum fanless 520W power supply, as the name implies this power supply boasts 80 Plus Platinum certification – this high efficiency is what allows it to operate fanlessly without any heat issues.

Packaging and Contents

Seasonic’s packaging is very tastefully done and plays heavily on the Platinum theme.

The back details the efficiency standards of the PSU as well as the promise of +-2% voltage regulation on all of the rails.

The accessory bundle is fairly generous relative to other PSU vendors; there is a power cable, some screws, a case sticker, normal cable ties, velcro cable ties and some documentation.

XFX XTS 460W Passive Fully Modular Power Supply Review

Introduction & Packaging

We recently reviewed the XFX XTS 520 power supply which was an 80 Plus Platinum, fully modular and totally passive unit. Today we have another power supply from XFX’s passive XTS range and that’s the slightly lower wattage XTS 460W model. There aren’t too many differences between this 460W model and the 520W model other than we’ve got a few less watts to play with. On paper the XTS 460 offers the same 80 Plus Platinum efficiency, the same fully modular design and the same excellent build quality, thanks to Seasonic being the OEM responsible for this unit’s production. If the XFX XTS 520 is anything to go by then this unit will have fantastic performance across the board with a fairly premium price tag to match, so let’s begin this review by taking a closer look at the XTS 460.

Packaging and Contents

The packaging details some XFX power supply features such as the EasyRail technology which basically means everything comes on a single 12 volt rail. The XFX XTS 460 is Haswell ready as it has full support for the low power C6 and C7 sleep states.

Around the back we get details about XFX’s True Wattage guarantee which basically states that you can use the full 460W this power supply is rated for without any issues.

Included with the XFX XTS 460 is a fairly simple package: a user manual, some silver screws and a power cable for whatever region you buy it in.

Antec High Current Pro Platinum 850W Modular Power Supply Review

Introduction & Packaging

When you think of Antec power supplies Seasonic instantly come to mind as they’ve been the OEM producer of a significant chunk of Antec’s products. However, when it comes to Antec’s extremely high end “High Current Pro” (HCP) platinum series, they actually use Delta Electronics. This is fairly interesting because Delta Electronics haven’t really had a presence in the consumer market for quite some time, instead they’ve focused mainly on the enterprise and server power supply market where the big money is. Whatever deal Antec struck up they’ve done well to get their HCP series made by Delta Electronics, inevitably this means they will hold a significant premium but in return you quite literally get a server-class power supply in a consumer package. Today we are taking a look at Antec’s HCP 850 power supply which is a fully modular and 80 Plus Platinum rated power supply. Right off the bat you might be surprised with just how big Antec’s HCP 850 is but the reason for that is simple: all that performance and quality requires additional components over a standard consumer power supply. If the fact Delta Electronics make Antec’s HCG 850 wasn’t enough to convince you, then the 7 year warranty definitely should. Let’s take a look at Antec’s HCG 850 and see exactly how it fares in our review!

Packaging and Contents

The front of the packaging features a glossy silver finish to accentuate the fact this unit is something special and Platinum rated. Antec quote up to 94% efficiency with 100% cable management (aka fully modular).

Around the back we find a list of features in multiple languages as well as various logos for the certifications this power supply has.

Included with the power supply is an overview guide, warranty statement, some cable ties, some case screws and a power cable.

Super Flower Golden Silent 500W Semi-Modular Passive Power Supply Review

Introduction & Packaging

If you want a truly silent system there are a lot of things to consider purchasing: a passive graphics card, a passive CPU cooler, SSD storage instead of mechanical hard drives and more importantly a passively cooled power supply. The advantages of a passively cooled power supply are numerous but the main advantage is that unlike most power supplies that will get noisy above 50% load a passive power supply never gets noisy. Other advantages include the fact that passive power supplies tend to require higher quality components in order to keep heat output down so when you buy a passive power supply you also know you’re buying quality and an efficient unit. Today I am taking a look at my second passively cooled power supply but this time from a brand not many people have heard of. Super Flower may not be well known as a consumer brand but Super Flower already feature inside many high-end power supplies sold by big brands, EVGA is the most notable one of those that springs to mind. In the UK market at least Super Flower are deciding to go at it as a standalone brand selling a wide range of their power supplies through Overclockers UK at very competitive prices. In this review I will be looking at Super Flower’s Golden Silent 500W passive power supply. This is an interesting power supply for a number of reasons: because it is 80 Plus Platinum rated, because it has a whopping big heatsink built into the PSU but also because the design has been built in its entirety from the ground up by Super Flower.

Packaging and Contents

The packaging has a rather strange butterfly theme to it, perhaps because butterflies are silent? The box also states this is an “OverClock Version”, I’m really not sure what that is supposed to mean in reference to a passive power supply….maybe something got lost in translation.

The back details the product features, specifications as well as the materials used in the product including the Japanese made Nippon Chemi-Con capacitors.

Included will be a user’s manual, power plug and four silver thumb-screws for securing into your case.

Super Flower Leadex Platinum 1000W Modular Power Supply Review

Introduction & Packaging

The brand “Super Flower” still doesn’t hold as much weight as other big brand names in the power supply industry, like Delta Electronics or the incumbent Seasonic. However, Super Flower have always been at the cutting edge of power supply technology and were among the first power supply vendors to bring an 80 Plus Platinum rated power supply to the consumer market. While Super Flower are best known for working with EVGA they have decided that they also want to go at it alone, like Seasonic they OEM produce power supplies for other brands and also sell their products independently. Today we are examining Super Flower’s top-end Leadex Platinum series and we have the 1000W model. What’s so interesting about Super Flower’s Leadex Platinum series is not just the beautiful aesthetics and innovative features but also the fact Super Flower are so much more competitively priced than equivalent units from the likes of Seasonic (sold under various other brand names) and from Delta (sold mainly under Antec).

Those unique features include universal modular connectors and a hybrid fan mode with two different modes of operation. Not to mention the unit is fully modular with all black cables, LED lighting, has a beautiful all-white powder-coat finish  and boasts incredible 80 Plus Platinum efficiency. The best bit really is the price but we’ll save the best bit until last so stick around until the end!

Packaging and Contents

Right away I’m going to have a quick moan: everything is white. Apologies for the difficult in picking up the product and its packaging because of this, sadly I did not have a black background. Anyway, so as we can see the packaging carries through the same white theme that the power supply has. The key selling point is obviously the 80 Plus Platinum efficiency which is presented on the front of the box as well as in the product’s naming.

The back of the box details the internal components used and information about the ECO Intelligent Thermal Control System. What this effectively means is that the fan speed is relative to the internal temperature of the power supply, the fan will only spin up when cooling is needed. This is a much smarter implementation than doing fan speed relative to PSU loading, the amount of load can only ever be a proxy for heat: you can assume that at 40% the heat level will be X but with the Super Flower implementation there are no predictions or assumptions: it is all temperature driven. Ultimately this means quieter operation as you don’t have to factor in a margin of error and climate variability which often sees power supply fan profiles set too aggressively.

The included package gives you a power cable, four black thumb screws (nice touch!) and a user manual.

They also present the main event in a nice cloth bag with a string tie, unnecessary yes but a nice touch nonetheless.

Seasonic Platinum Series 660W Modular Power Supply Review

Introduction & Packaging

Since joining eTeknix over 3 years ago I’ve seen us work with a lot of big brand names and have personally done countless reviews with those brands. Power supplies are something I’ve been covering for just over a year and in that time Seasonic is a brand we’ve never worked with directly. The word “directly” is key as Seasonic “indirectly” work with just about every website that reviews power supplies because so many power supplies are built by Seasonic and rebadged to be sold by other brands: Antec, Cooler Master, Corsair and XFX are just a few brands of many who work with Seasonic to produce power supplies based on their OEM designs. Today we finally get to take a look at an actual Seasonic product and it is something fairly special: Seasonic’s 660W Platinum Series power supply. As the name suggests it boasts incredible 80 Plus Platinum efficiency as well as a fully modular design, a staggering 7 year warranty, high quality components and construction and support for SLI, CrossFire and Haswell C6/C7 low power states. Seasonic have always been at the forefront of power supply innovation in the desktop and server markets so we have absolutely no doubt that this power supply will match or even exceed our expectations.

Packaging and Contents

Seasonic’s packaging plays on the Platinum theme with a silver-coloured box. It points out clearly the wattage, efficiency and the Haswell-ready certification.

The back details the key product features which includes the promise of +- 2% voltage regulation on all rails and a hybrid fan that only spins up at around 30~% load.

Inside the packaging we find everything is nicely presented and very well packaged – this certainly won’t get damaged in transit.

Included accessories with the power supply are a power plug that will reflect the region you buy this unit in, an owners manual, Velcro cable ties, standard cable ties, a Seasonic sticker and four silver screws for mounting.

XFX XTS 520W Passive Modular Power Supply Review

Introduction & Packaging

For PC users who are serious about noise there really is no alternative to a passive power supply. Sure there are power supplies on the market that operate incredibly quietly (such as Be Quiet’s Dark Power Pro range) and even power supplies that don’t spin up their fans until they pass a certain load amount, normally 40% load (Corsair’s AXi range for example). However, a fan is still a fan whichever way you butter it up and a fan means some noise irrelevant of how quiet that fan is.

Enter XFX’s latest passive range of power supplies dubbed the XTS series. Today we are checking out the XFX XTS 520 which is a totally silent, passively cooled 520W power supply with a fully modular design, 80 Plus Platinum certification and a 5 year warranty. This really is the bees knees of power supplies and while 520W may not sound like much, that’s easily enough to power a Core i7 4960X system with a GTX Titan Black and a tonne of hard drives or SSDs, lots of memory and a full sized ATX board. With that said the XFX XTS 520 is a power supply that is versatile enough for any system from a low-end workstation to a high-end gaming PC: you can even run SLI or CrossFire with this power supply.

As with all XFX power supplies the XTS 520 is based on a Seasonic OEM design: this means it is going to be a quality piece because Seasonic are one of the top vendors in the entire power supply industry. Let’s start this review by taking a look at the packaging of XFX’s XTS 520.

Packaging and Contents

The packaging features images of the product as well as all the relevant certifications of SLI, CrossFire, 80 Plus Platinum and the fact it is Haswell C6/C7 low power state ready.

Moving around to the back and we find that the packaging details more features about the power supply. XFX note the use high quality 105 degrees celsius rated Japanese capacitors which is always nice to see and reassures you about the quality of the product.

Included with the power supply is a brief user manual, four silver screws for securing into your case and an EU-style power plug. We expect that the power plug will reflect the region within which you buy the product (unless the retailer you buy from is selling imported stock from other regions).

Seasonic Presents its Latest PSU’s at Computex 2014

PSUs play a great role in desktop configurations and with the new technologies coming out soon, Seasonic saw fit to present their solutions as well. The company has revealed at Computex 2014 its 80 PLUS Platinum series 1050 W and 1200 W, the upgraded 80 PLUS Gold X series 1050 W and 1250 W models, as well as the 80 PLUS Bronze series.

Looking at the 80 PLUS Gold X series, Seasonic appears to have made the series fully modular. What that means is users will not have to deal with a whole bunch of unused cables taking space in their PC case, rather the company has given the ability to choose what cables the user requires and giving him the option to manually attach them. Also, the X series PSUs have been granted the Hybrid Silent Fan Control support, in addition to an upgraded D2D platform.

The latest and most powerful of the series, the 80 PLUS Platinum series, having an up to 92% efficiency, is said to feature a full array of ultra-efficient power supplies, ranging from 400 W to 1200 W, having all models fully modular. A special fanless model will be included in the series which Seasonic believes will be ‘sought’ by many users for its performance and noise level ratio.

Seasonic has introduced a new Honeycomb structure air vents design to both of its PSU series described above, including the 80 PLUS Bronze S12II, with efficiency of up to 85%, allowing for an optimum air circulation and heat dispersion. The S12II also seems to feature black-coloured flat cables and silent 120mm FLuid Dynamic Bearing fans. In addition, the 80 PLUS Bronze M12II Evo features all of the S12II’s characteristics, along with Fluid Dynamic Bearing fans and an extreme silent mode, activated when the PC is not requiring a lot of power to process applications.

Antec EarthWatts Platinum 550W Non-Modular Power Supply Review


When it comes to the Antec Earthwatts Platinum series efficiency is the order of the day. Antec’s Earthwatts Platinum series benefits from being one of a few 80 Plus Platinum power supply ranges available in, what we might term, more ‘mainstream wattages’ such as the 450w and 650w models we reviewed recently here and here. Typically other 80 Plus Platinum power supplies are of a more extreme/enthusiast stature such as Corsair’s AX1200i/AX1500i, Enermax’s Platimax series or Be Quiet’s Dark Power 10 850W.

With that said today we are taking a look at the Antec Earthwatts Platinum 550W power supply which is an affordable 80 Plus Platinum power supply with a wattage that can cater for the majority of mainstream and mid-range systems. The 550W Earthwatts Platinum shares all the same features of other power supplies in the series which includes a non-modular design, being based on the FSP Aurum platform and being compact in size. So without any further ado let’s proceed with having a look at this product, and how it performs.

Antec EarthWatts Platinum 650W Non-Modular Power Supply Review


Power efficiency is a significant consideration for any system that is running frequently – a home server, mining system, a workstation or any other system that gets close to 24/7 usage is a prime candidate for a high efficiency power supply. With the need to cut electricity related carbon emissions, and consume less electricity in the wake of rising electricity prices, the time to get an efficient power supply is now – particularly if you are upgrading from an old unbranded power supply that lacks any form of certifications or efficiency standards.

The 80 Plus standard has been around for a while to ensure that customers know what they are getting in terms of efficiency. At the top end of this efficiency standard is 80 Plus Platinum which promises 90/90, 92/94 and 89/91% efficiency at 20%, 50% and 100% loads on 115/230V circuits respectively. Antec’s EarthWatts Platinum series is designed specifically to meet those certifications and offer consumers affordable 80 Plus Platinum power supplies in a range of sensible wattages. We’ve already reviewed Antec’s 450W EarthWatts Platinum power supply and today we are moving on to the 650W variant. With the EarthWatts Platinum 650W power supply Antec are seeking to capture some of the higher end market – 650W is more than enough for a dual GPU system. Like other power supplies in this same series this unit is made by FSP, is non-modular and is backed by a three year warranty. Of course there is more to a power supply than just efficiency so let’s move onto having a look at this power supply and see how it performs.

be quiet! Dark Power Pro 10 850W CM Semi-Modular Power Supply Review


I spend a lot of time reviewing, not surprising given that I’m a reviewer, and it can often get very tedious at times. But one thing that always cheers me up is high quality products that are a bit special and different to what I’m normally used to looking at. be quiet! are one of those brands that always deliver high quality products that are a little bit special and the “German Engineering” they offer shines through. Their power supplies are certainly no exception to that and even though they employ other OEMs to produce the internals of their PSUs they are never just simple “rebrands” like we’d see with Antec power supplies for example. be quiet!’s Dark Power Pro 10 series offers up a whole series of unique modifications including an OCK switch that swaps between multi-rail and a single rail design, fan headers for fan control on the power supply, integrated anti-vibration pads and of course be quiet!’s own Silent Wings fan. Even that last addition, a be quiet! Silent Wings fan, may sound small but look at how many companies produce power supplies but do not use their own fans – Corsair and Antec are two reputable examples of that.

With all that said today we are taking a look at the rather special be quiet! Dark Power Pro 10 850W CM power supply. This is one of the be quiet! upper mid range wattage Dark Power Pro 10 series power supplies sitting above the 550, 650 and 750W units but below the 1000 and 1200W units. In terms of be quiet!’s product stack the Dark Power Pro 10 series sits at the top being their most premium product. You can certainly tell and even from just opening the box the attention to detail is exceptional. Before we proceed onto the rest of the review be sure to check out the product specifications below so you know what we are working with today:

Corsair AX1200i Modular Digital Power Supply Review


When it comes to “uber” high-end and high-wattage power supplies there is one name that stands out from the crowd and is widely recognised – the Corsair Ax1200i. Today we have managed to get our hands on this somewhat revolutionary power supply to bring you a review. The Corsair AX1200i isn’t redefining the wheel but what it is doing is changing the way power is typically delivered. The Corsair AX1200i is one of few power supplies to take advantage of a digital power delivery method or what Corsair are calling “Hybrid Digital Control Architecture”. In short this means the AX1200i uses a server grade Digital Signal Processor (DSP) combined with a power train architecture. The AX1200i as a result can make on the fly adjustments to control and monitor voltage and stability in real time. The DSP also allows for automatically DC output compensation to hold stable power, prevent droop and minimise ripple & noise in the power outputs.

Other digital aspects of the Corsair AX1200i include a digital interleaved power factor and a digital PWM control. This allows the power supply to continually adjust in real time to maximise PFC and minimise acoustic output. We can of course go on forever about the mechanics and internals of this particular power supply, but digital components aside this is still a conventional power supply, though the digital aspect should have a significant impact on performance. The specifications of the power supply that Corsair provide on their website product page can be seen below:

As we progress through this review it is worth keeping in mind the key principles of the Corsair AX1200i to see if it delivers on those. Corsair point out the following:

  • 80 Plus Platinum Efficiency
  • Low noise and Fanless operation at 30% or less load
  • Ripple/Noise 3X better than ATX specification

Antec EarthWatts Platinum 450W Non-Modular Power Supply Review


With energy efficiency becoming more and more important to consumers it was only a matter of time before 80 Plus Platinum was made available in low-wattage power supplies for relatively affordable price points. Currently we see 80 Plus Platinum reserved for high end power supply units like Enermax’s Platimax series and Corsair’s AX1200i among others. Yet today we have with us an 80 Plus Platinum rated power supply from Antec in a modest 450W capacity for users who care about energy efficiency and only have a modest system to power. The Antec EarthWatts Platinum 450W power supply we have here today fills exactly that market segment.

The focus of Antec’s EarthWatts Platinum series is really quite simple, they want to offer you 80 Plus Platinum rated power supplies that are more affordable because they come in more realistic wattages for “normal” systems. In fact 450W is more than enough power for any high-end system. You could easily run a single high end GPU and high end CPU platform off this power supply, such as an Core i7 3960X with a moderate OC and an Nvidia GTX 780. Of course the typical user of this power supply is more likely to have an LGA 115X platform and less demanding GPU but the point still remains – 450W is enough for most people making this a very accessible and applicable power supply.

Antec’s promotion of this product pulls a load of questionable figures out of the air in terms of how much money you could typically save. Realistically the amount of money you can save is going to vary wildly on three factors:

  • Your unit cost of electricity
  • How efficient your previous power supply was
  • How often you use your PC and related to that how much electricity it consumes when you use it

So as we proceed through this review it is worth taking a note that the focus is very much on efficiency, so without any further ado let us get straight on with this review.

Enermax Platimax 850W Semi Modular Power Supply Review

Enermax are one of the biggest names in high end power supplies these days and the Platimax branding has recognition throughout the industry as being one of the most efficient power supply units available thanks to its association with the 80 Plus Platinum certification. Today we have with us one of these units as we test the Enermax Platimax 850W power supply. The Platimax series from Enermax is aimed at the top-end user and the particular unit we have with us today, the Enermax Platimax 850W, is aimed at the user with dual GPU configurations (SLI or CFX) and quite a thirsty overall system.

Enermax certainly haven’t skimped out on this power supply and are throwing an impressive 5 year warranty behind it, a custom 140mm Twister bearing fan, high quality components and a whole range of protections and certifications. If you are looking for a high-end power supply then Enermax certainly give the impression that this is one of the best options, but as always let us find out if this is the case as we put the Enermax Platimax 850W through its paces in this review!

Computex: InWin Reveals Serenity Series Power Supplies

Although InWin’s cases have been stealing the show at Computex 2013, namely the King Size H-Frame and Tou Glass Case, their new Serenity series of power supplies didn’t go unnoticed by us. We went on over to check this new power supply out and it features a chrome brushed steel finish. As you can see from our pictures by the time we got around to it the unit was ravaged by finger print marks so its worth considering this if you want to buy it – definitely handle with gloves to keep it in pristine condition.

The power supply internals are rated for 80 Plus Platinum and offer full range APFC. They have a single rail 12 volt design and common PSU protections like OCP/OVP/OLP/UVP/SCP and various certifications for regions like the ErP lot 6 2013 for the EU. The units are approximately 18cm in length and are semi-modular.  The 20+4 pin motherboard connector, 4+4 pin EPS CPU connector and a pair of 6+2 pin PCI express connectors all come pre-fixed.

The rest of the modular cables provide two to four 6+2 pin PCI express connectors and up to 22 peripheral connectors (16 SATAs and 6 Molex). The Serenity series does support Haswell C6/C7 power supplies and it is cooled by a 120mm double ball bearing fan.

Computex: Rosewill Display Silent Night Passive/Fanless Power Supplies

Fanless technology seems to be ramping up in the power supply market this year as we are seeing passive supplies with growing capacities. Typically we’ve only seen 300/400 and 500W passive power supplies at a push. However, on the back of Enermax showing their fanless 550 and 650W power supplies, Rosewill have also displayed their 500 and 600W passive Silent Night power supplies too.

The aptly named Silent Night series has 80 Plus Platinum certification and a fully modular design. Rosewill didn’t really tell us any specifics about the Silent Night power supply but given the 80 Plus Platinum rating we can expect some high quality hardware inside. There is also extensive venting through the casing to allow for ambient air to flow through without obstructions.

Rosewill, like with most new products announced at Computex, did not announce pricing or availability but we expect them to be available shortly after Computex and will most definitely be available in North America on since Rosewill is Newegg’s in-house brand.

Computex: Rosewill Show Digital “Epoch” Power Supply

Rosewill are becoming quite a potent player in the computer hardware market rapidly expanding their portfolio to peripherals, cases, power supplies, networking and so on. They just unveiled a new power supply too at Computex 2013. This power supply is dubbed the “EPOCH” and is available in 850/1000/1200W capacities, Rosewill demo’d the 1200W model. What’ so interesting about these, apart from the 80 Plus Platinum certification, is that they have digitally controlled power.

As you can see from the provided software there is total digital monitoring and control of your power supply and there is even the ability to tweak your rails between dual and single 12 volt rails. In fact to this software looks strikingly similar to the SilverStone Zeus ZM1200 power supply we have already seen today so I can safely say these power supplies have a shared OEM producer.

The power supply becomes digitally connected via a wireless dongle on the back of the power supply which transmits to a wireless USB dongle you input into your system. These communicate and allow you to use your software to monitor and tweak your power supply.

Rosewill have not announced pricing or availability but expect it to come very soon.

Computex: SilverStone Show Zeus 1200W Digital Power Supply

SilverStone are pretty well know for their high quality power supplies and at their Computex booth they took the time to show us their new high quality Industrial Zeus 1200W digital power supply. This power supply is rated for 80 Plus Platinum and has a very high quality design. You can even see a magnetic dust filter comes attached to the fan intake meaning you don’t even required one on your case.

What is so special about this power supply is that it uses a digital design and as far as I am aware the digital outputs of the PSU are carried into the system via these USB dongles. This power supply is an updated version of the old Zeus ZM1200 power supply SilverStone released many years ago.

The digital output can be read by your operating system using the provided SilverStone software and as you can see it gives you the options to monitor all your settings as well as pick between single or quad 12 volt rails.

Computex: Enermax Display Fanless Series Power Supplies

Enermax have been displaying their premium fanless power supply series at Computex this year. They showed us their fanless series which consists of 550W and 650W models and as they are both totally fanless they are also both totally noiseless. The wattages Enermax have managed are pretty impressive as most fanless power supplies are only available in 350-500W models let alone 650W.

Enermax achieved this high power fanless possibility by getting 80 Plus Platinum certified components that create minimal inefficient heat wastage. They also come ErP Lot 6 2013 certified.

The design of these power supplies is aimed at the really premium user – that is someone who has the cash to make their system totally silent and these PSUs will not be cheap. As far as we know these units will be announced next month sometime and available in August October sometime. The 650W unit will cost around £170 while the 550W unit will probably be about £140 based on what we learned from CeBIT this year.

These units use a Directly Heated Triode and a Copper-Bridge Array Transmission.
