Performance (40% of the final score) – this should be super easy today. Voltage regulation couldn’t have been much better than this unit showed, coming in at 0.25% in the hot box. No points removed for mythic level performance there. Ripple control was similarly outstanding with all three main outputs holding inside excellence, so no deduction there. Power on spike performance was good enough to let the unit have that whole point, so we’ll go on to efficiency. On that front, what wasn’t Platinum was Titanium so you better believe that’s worth full marks. That means this unit gets a much coveted 10 here for performance.

Functionality (20% of the final score) – I have got to remove a full point for the indy sleeving on those cables. Once again, they look nice but that’s about all they have going for them. But other than that, I see nothing else to whine about. Documentation was great. Lots of accessories. Fanless mode. In just about every way, Corsair kills it here. 9.

Value (20% of the final score) – this unit isn’t quite on the market yet, it seems, so we’ll go by the MSRP of $139.99. It’s just a bit more money than the Silverstone SX650-G and EVGA 650GM, but better performing than both and more efficient. 10.

Build Quality (20% of the final score) – absolutely flawless. Not one thing to complain about here. 10.

Cables. I literally came within a set of cables from giving out the first perfect score in quite some time since my scoring methodology tightened up to avoid giving out too many of those. The SF600 Platinum took what was already one heck of a good power supply and made sure it was ready for a few more years of total SFX market domination. Want something more efficient? Can’t be done without going to SFX-L to get that one actual Titanium unit on the market. Want something better performing? Such a creature does not exist to my knowledge. Want something cheaper? Well, then you have to compromise somewhere, mostly on performance.


  • able to hit Titanium efficiency at times
  • crazy high standby efficiency
  • mythic level voltage stability
  • excellent ripple control
  • tons of goodies
  • semi-fanless
  • fully modular
  • fantastic build quality
  • long warranty

The BAD:

  • are you kidding me?


  • fanless mode warning sticker leaves residue… like that’s going to keep us from buying it
