Corsair SF Series 600W Power Supply Review

Manufacturer: Corsair

Introduction and Features


Corsair continues to expand their extensive power supply lineup with the addition of two new small form factor (SFX) units, the SF450 and SF600. The SF Series power supplies are fully modular and optimized for quiet operation and high efficiency. Both power supplies feature Zero RPM Fan Mode, which means the fan doesn’t start to spin until the power supply is under a moderate to heavy load. The SF450 and SF600 are 80 Plus Gold certified for high efficiency and come with a 5-year warranty.

While the SF Series is designed for use in small form factor enclosures, Corsair’s SF Series power supplies can also be used in standard ATX cases to save room via the optional SFX to ATX adapter bracket. As you can see in the photo below, the SF Series power supply is much smaller in all three dimensions than a standard ATX power supply. We will be taking a detailed look at the new SF600W power supply in this review.

It can NOT be used in standard ATX cases because the cables are too short!

Number 1. He means cases that use "standard" ATX power supplies. Number 2. Obviously you wouldn't use this in a full sized tower like a Corsair 900D. And why would you? Number 3. You can purchase longer cables and/or extensions if you had to. A small ps like this is more than likely going to be used in a smaller environment. What would be the point of putting this into a mid or full sized ATX environment? None.

Watercooling in a midtower maybe? I have one sf600 in a itx environment but i was asking myself the same question. The only answer i found is more room for water pumps/ watercooling tubes in a atx/itx case.

Per example: the fractal design nano S/ phanteks evolv itx cases are on the big size of itx case and they do support normal atx PSU but a SFX psu like the sf600 could make the difference in the watercooling space of somebody

At the moment there's no longer cables for the sf600, BTW don't tell people to get longer cables, they are different, in many ways ,and can ruin a system. thanks

The picture supplied by Corsair labeling what the parts are matches my SF450 PS. #16 uses blue colored caps versus the red shown for SF600, is all i can see is different.

I've got the 450 watt running in an unRAID server build. Powering 6 drives and I can't say I've ever seen the fan come on. I had to order a separate bracket to fit in the case though. Even though the case will only fit an mITX motherboard and barely anything else, the cut out is for a full size ATX PSU. Case is a Lian-Li Q25B. Awesome little case for a NAS box or anything along those lines.

If these had been around when I built my HTPC, I'd probably have stuck a 450W in there. Instead, I ended up with the Silverstone SFX-L 500W - not bad at all, but inside of a Fractal Node 304 you take all the extra space you can get. Also, these seem to perform admirably. Good to see Corsair making an effort when they only have a single SFX line (although Platinum or Titanium efficiency would be even better, of course).
