The X-Series 650W power supply from Seasonic is unique in being a high powered modular power supply with the 80 PLUS Gold rating. It also has a unique cooling setup, in that the 120mm fan turns off entirely at lower power loads. Between that and its overall efficiency rating in excess of 87%, this unit provides both a high level of power and a reliable, quiet configuration.

This power supply is extremely efficient, and will completely turn off its fan under low load (such as when your PC is idle). It is a great pick for a silent PC.

I have a power supply from this same line in my small form factor desktop system - and the fan does indeed turn off at low power draw / heat levels (making it great for a quiet system). When it comes on I can just barely hear it, and my quiet Asus video card usually makes a little more noise - just enough to mask it - since a heavy load on the power supply means I am probably gaming.
