Corsair SF600 80 Plus Gold Fully Modular SFX Power Supply Review

Introduction & Packaging


The world of Small Form Factor (SFX) power supplies has been a fierce battleground over the last few years. Gaming systems have been getting smaller, the HTPC and Steambox markets are growing in popularity and the demand for a tiny PSU that can keep the system small, but still deliver the high-performance grunt required by modern gaming GPU/CPU combos is at an all time high. Enter the new Corsair SF600, the latest contender on the market and judging by the specifications, it may be the best one we’ve seen to date.

“SF Series power supplies bring legendary Corsair performance and reliability to the SFX small form factor standard. They have the features found in full-size high performance power supplies, with certification for 80 PLUS Gold efficiency, superior voltage regulation, Zero RPM mode for virtually silent operation, and 105°C All Japanese capacitors for better reliability.” – Corsair

Equipped with 600W of power, more than enough for any high-end and overclocking gaming rig with a single GPU, 100% Japanese 105c capacitors, a zero RPM fan mode for ultra quiet performance at lower loads, fully modular cables and that super compact SFX form factor, the SF600 is certainly an attractive unit. To make the deal even sweeter, it comes backed up by Corsairs confidence inducing 7-year manufacturers warranty!

The packaging is very nicely designed, keeping in theme with other current Corsair product ranges and featuring a clear product image and the main specifications prominently displayed.

Plenty of technical information around the back too, showing off the efficiency and fan speeds at various load scenarios.

In the box, you’ll find two protective bags, one for the cables and another containing the PSU. There is all the usual documentation, a mains power cable, cable ties and screws; everything you need to get you setup and ready to rock.

Corsair Releases New SFX SF600 and SF450 PSUs

Building compact high-performance systems can be troublesome in many areas, not because people lack the skills, but because there was a lack of components to do so on the market. We’ve seen an increase in compact motherboards and graphics cards that still deliver great gaming and workstation performance, but there has been a shortage of quality power supplies with high ratings, actually there’s kind of only been one up until now.

We already had a little preview during our visit to CES in January and now Corsair is ready to release their new SFX power supplies with proper certification and a fully modular connection system. The two new power supplies are the Corsair SF600 and SF450 that come with 600W and 450W respectively.

Compact system builds have an additional challenge besides the component size and that is the available cable routing space. With that in mind, it’s great to see that the new SF600 and SF450 power supplies come with a fully modular cable system. You can detach all cables from the unit itself for easy cable routing while building and minimize the cables in the chassis to only those you need.

Corsair is well known for their power supplies and they didn’t skimp out on their new SFX series either. The units are fully 80Plus Gold certified for an optimal efficiency and less heat generation. Speaking of heat, the Corsair SFX PSUs are built with a 90mm fan featuring Zero RPM Fan mode. The fan is only turned on when it is needed and only spins as fast as it is needed. The small you make something, the better the build quality has to be.

The small you make something, the better the build quality has to be in order to have a long lifespan. That’s taken care of in the SF-series by the use of 100% Japanese capacitors and the units are backed by Corsair’s well-known 7-year warranty.

The SF450 is available immediately worldwide from Corsair’s worldwide network of authorized retailers and distributors. The SF600 will be available shortly and is available immediately for pre-order. The MSRP is set to $89.99 and $119.99 respectively, excl. Tax.
