Summary: This thing is dead quiet, and like a really good power supply, I never notice it. It powers my gtx770 and a few hard drives and fans easily. The modular cables are quite nice, I can plug in just the cables I need and leave the rest in the neat bag that came with it.
Awesome PSU, really cool monitoring software, but it suffers from a poor UI and bugs.

Summary: Expensive for a 760W PSU, but this thing is ultra efficient. I average around 92-94% efficiency with this thing. The software doesnt have the best UI, and it can be quite buggy. However, it is still awesome. There is no other PSU that you can extensively monitor like this one.
DIED AFTER 15 MONTHS AND REPLACEMENT SERVICE FROM CA TAKES A WHOLE WEEK TO PITTSBURGH!!!!

Summary: Purchased this June 2013 and it died Oct 2014, hosing my windows in the process. (I let the power fail one time too many before I stopped using the PC). Of course, this happened on a Saturday and Corsair is only open M-F. So Monday morning, I called Corsair and had a replacement sent.
Summary: I just wish they had better instructions. The options are great. The thing works really nicely, the fan has never come on during operation, so I guess I over estimated my need. But still VERY nice.
Summary: Set it and forget it. I installed this unit in a 4770k build with a radeon 5870 gpu. The system under max overclock of both the cpu and gpu can only generate 400 watts or so. With that said, typical idle usage sits around 75 watts and even at roughly 10% output i generally get around 80% efficiency.
Summary: I bought this to power two gpu's that I bought a couple months ago, and it is quiet, the fans rarely turn on and when they do they are pretty quiet. There are lots of options for cables, and I really appreciated that. Would recommend.
