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: 1000 Watts for $100 is unbeatable. I was going to go with another PSU but I didn't want an always on LED light so I went with this one due to the brand name. It's my first Corsair and it powers my rig like a champ (I have a 8350 OC'd and a 295x2).
Pros: Price Wattage Performance Modular Tons of cables
Cons: On/Off Fan Speed/Noise Light Coil Whine Stiff Cables
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: Completely silent during normal operation. Fan doesn't need to run, until more than 40% load. Running with I5 4690 and NVidia 970 power supply fan stays off except when gaming. Haven't put case sides on yet so power supply is still whisper quiet even from few inches away.
Pros: I'm very pleased with the wide variety of PSU's (power supply unit) Corsair has to offer. I'll admit I was a little confused about all the models they had. ex. AX, HX, RM, CS, CX & VS. However after researching them on Corsair's website, it made the choice for me much easier. The fan is very quie...
