Performance (40% of the final score) - and now we come down to the scoring, and this is going to be a snap. Ripple suppression was excellent. Voltage regulation was very, very good. The unit stayed pretty quiet, even in the hot box. And it topped out at 91% efficiency too. I can't in good conscience give the Antec 850W units perfect scores here and then go knocking points off on this unit, so here you go Corsair... your first 10 from me in performance.
Functionality (20% of the final score) - oh, man... how is this unit hurting in this area? The modular cables are the flat kind, easy to hide. There are enough connectors to hook up a boatload of hard drives. There are almost too many connectors for video cards. If I had to complain about anything at all, it might be the unit's depth. It's an awesome unit, but at 180mm deep I can see some poor guy sitting in front of his case, HX850 to one side, sobbing into his hands because it won't fit. This unit isn't country mile long like some of the kilowatt size units I've tested, but it's just long enough to be a possible pain. Half a point off for that. 9.5.
Value (30% of the final score) - Provantage currently has the best price on this unit at $190.28. That makes it about $17 cheaper than the lowest price I can find on the Antec SG-850. That's a win for Corsair, because this unit comes up pretty much dead even in keeping up with that one in terms of overall performance. But, I do find that the build quality of this unit what with the perpetually loose heatsink screws is lagging behind somewhat. So, I'm going to hand out a 9 here.
Aesthetics (10% of the final score) - like all Corsairs, it looks good to me. 10.
The long wait for a modular 850W unit from Corsair is at last over, and I do hereby declare that this unit was worth waiting for. Not only is this the most efficient Corsair I've ever looked at, it's also the best performing. Now, all Corsair needs is a CWT DSR or similar unit to sit on top of the mountain as an HX1200, and Corsair will be laughing all the way to the bank. Not that they aren't already.
12V ripple suppression second only to a very few high end units
very, very stable regulation
loose heatsink screws yet again
take the children and yourself and hide out in the cellar... I'm about to break out my Mike + the Mechanics collection and I'm not going to be shy with the volume knob
