Summary: Since when does a 850W Gold Rated PSU cost the same as a additional GPU? I've been in the computer building scene for years and I never bought into these pricey PSU's. The only reason this power supply is in my current build is due to it being purchased used in a pre-built system.
Pros: Appears to be a good power supply, fan only comes on when under load.
Cons: There is a whinning/chirping noise for about a minute when the fan comes on. Then the noise stops, not sure if it's worth returning for this problem. A power supply that costs this much should be totally silent. I gave it only 3 eggs because I hate noise in psu's.
Pros: Works totally fine as a power supply. Never had any problems with it feeding any of the hardware in my case. The modularity is nice as well.
Cons: The fan is very noisy. I kind of can't stand it, and have actually been avoiding playing games lately because of it.

Summary: I want to RMA, but am scared I will get sent an even worse unit... also have no replacement PSU so... Sad thing is my friend's CX600 is dead silent and works perfectly... Corsair Support, if I RMA, will you promise not to send me some refurbbed ticking timebomb of a PSU...
Pros: It has a powerful +12 rail with plenty of amperage to power any 2 single GPU's with virtually any CPU as well. Currently only have one 290, but might CF soon with this
Cons: When the fan spins up, and the PSU takes on a power load, the PSU sounds like chirping birds, a scraping chalkboard, a teapot steaming up all at the same time...It overcomes the noise of all 9 fans, my GPU's fans, the CPU fans, and even my PC's speakers... My PC would be silent if it wouldn't be ...

Summary: ... I've tried to turn my new Radeon 7970 on by using the optional cables (modular) that came with this PSU. I had to skip using this cables and used the ones that are attached in the PSU, and only after that my 7970 worked.
