Summary: I've never been sensitive to fan noise but I don't like how Corsair rigged this fan. It's off at low load but moderate to high loads it spins up way more than necessary. There is no switch to control the fan. Add one of those and this would be a great PS.
Pros: Cheap for wattage, modular, Corsair has a good PSU reputation. No coil whine on mine. Appeared brand new, not a scratch on it, no dust.
Cons: Fan goes from 0 to 100 at moderate to high loads. Eventually spins down but is still loud. My test was with one 290, three hours of gaming, no headphones, case ~4 feet away.
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. Though it's advertised as a thermally controlled fan, it doesn't exactly gradually ramp up under high temps. Rather, it stays seemingly silent until it really needs to work, then j...
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 bought the corsair hx1050 80+ gold to power x2 gtx 780's in sli and my i7 2600k . i only had this power supply for one week before i returned it . the reason i returned it was because when ever i was gaming it got very loud it got so loud that i was scared some thing was wrong with it .
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.
