Whoop Whoop.... 650W PSU has just landed on my desk.... should be able to run a few servos from that!
Sweet, keep an eye on your voltages when you first test it out. The first test i would do is to cross load it REALLLY heavy (put a heavy load on the 5V line and a minimal load on the 12V line) and see how far out of spec it goes. Most modern PSU's do not enjoy being cross-loaded though good ones handle it fine just their efficiency suffers, the bad ones just go nuts.
