Newegg.com has this PSU as a Shell Shocker:
Antec NEO ECO 620C 620W Continuous Power ATX12V v2.3 / EPS12V 80 PLUS
Certified Active PFC Power Supply

It's the best PSU you're gonna find for $35 by a long shot. I picked one up
at this price a couple months back and have been very happy. It can handle
any single graphics card and easily up through two Radeon 6870's in
Crossfire.
