The Thermaltake Purepower 560w unit should be at the top of anyone's list who needs a new PSU. Not only do you get a truck load of power but you get it at a very low sound level. The fan speed adjusts as temperature rises. Over three days of playing with the Purepower unit, I never found the sound level to be anything more than barely perceptible and that was only when I was consciously listening for it. The cable sleeving and shrink wrap will go a long way with you need freaks out there like me. Another nice plus was having two true SATA power connectors. Many power supplies handle this through an adapter (extra unwanted clutter). Tt has seen fit to address this properly by having a separate line for any SATA drives. As we started out saying, if you need a new power supply this is it. The only down side right now is its price and availability are questionable at present. Special thanks to Thermaltake for making this review possible.
