Quiet, effecient, versatile, and good price-to-peformance. Review for 850 watt version. Would be 4.5 if possilbe.

Summary: I upgraded from a CX500 to this quiet optimized PSU and have been extremely happy. Pros: Noise: As advertised the unit is extremely quiet. There is absolutely no detectable coil whine, and the fan is also nearly silent. Also, the fan does not operate at all under idle and small loads.
Summary: OMG this is the fastest free shipping i have ever gotten from amazon ever. I love the feel of the corsair 850W feels like its very good build and amazing quality. Im so happy i'm going corsair every fan in my case is corsair and i'm very proud to have corsair power supply in my case.
Summary: The 80+Gold rating on this power supply is what first got me here and then the corsair quality is what really made it stand out. This is definitely one of the more expensive 850Watt power supplies you can by but this thing is worth it.
