The EVGA SuperNOVA 850W is a full-featured, 80 PLUS Platinum-certified power supply unit - complete with entirely modular wiring for clean assembly and a 140mm fan for cooling. Its ECO fan mode turns the fan off entirely at low power draw levels, and even when it spins up the fan remains relatively quiet.
William George (Marketing Project Manager) Says:
The fan on this unit is slightly louder than the one on the Seasonic 850W power supply we carried before it, but that only matters when the load is high enough to cause the fan to turn on. In trade for that slight downside, the unit puts off less electrical noise - making any actual impact on noise level under heavy load pretty much even. It is more efficient, though, with ~92% peak efficiency.

In my opinion, when you're building a computer the power supply should be the most important component in your system. If your power supply dies, there's a probability that it can take other components with it. EVGA has always been one of the most reliable manufacturers when it comes to computer components, & their track record shows that. There's only 1 downside with this unit & that's the fan. It's a little louder than what we are accustomed to hearing, but in no way is it bothersome. Actually, due to its 80 Plus Platinum (~92%) efficiency & Eco Mode, the fan rarely turns on.
