Summary: Wish it had an multi-colored LED fan. Perfect, worth every cent. Corsair Link let's you view it's power usage real-time and over a given length of time. It is a pretty awesome feature. Individual rails for graphics cards, which is what I needed for my Dual SLI Gigabyte GTX 980's.
Summary: Would love to rate this better, but definitely a faulty piece of junk. My first one died within 2 days, quickly I received a new replacement hoping to get my new system up and running. I decided to perform the self-test prior to connecting anything into my system and no light.
Summary: ROCK solid power supply. I'm thrilled with it's operation and the fact that it almost never even kicks its fan on - probably because I'm not pushing it hard enough. But, its clean power, nice modular ports, solid construction and high efficiency are real winners.
Summary: So I would call myself a Corsair fan boy seeing as I have so many Corsair things, BUT that doesn't mean I didn't do my research. I read the review of Johnyguru, a very scientific site and thorough site, and saw that it was actually a very good PSU.
Summary: Got this at a great price(around 300 bucks). It was 369 at my local store.. This thing is a beast,its quite,got more power then anyhtign I will hook up needs. Only con I felt a lil ripped off they Give tool kits and sticks with the 850,s but this came with nothing but a sticker .
