600W SilverStone ST60F is actually 650 watt, but they lowered the rating because of the modular connections.
4 very stable 12v rails and plenty of power for Crossfire.
Mine was blowing into the case, but that was easily fixed. They also answered the phone on the first ring and my hold time was less than 10 seconds will being transfered, so great customer service if you ever need it.
All cables are very nicely sheathed except for the last 1.24" near each connector, and the extensions are not sheathed. So the molex connectors are sheathed from the PSU to the first molex, then bare wire till the second molex and bare wire for the floppy connector when it has one.
The above is my only complaint, but I'm anal about not having bare wires showing inside the case.
