I got a coolmax 400 Watt (Pfst!...) Power supply free with a Cooler Master case on Newegg. I build a Rig with it and sold it to a client of mine. It would spontaniously reboot he put up with it for a few months but wanted me to fix it before wannanty was up. I went to replace the mother board with my old but beloved Asus P4C800 Deluxe cause that was the same Socket it would not boot. That Darn power Supply Was BAD! I replaced it with another Coolmax 450 Watt. Now it works Fine and I have switched to SeaSonic Power Supplys.
