Take a look at the Corsair 1000W, Ultra X3 850w or 1000w, and the Thermaltake 850w, 1000w, and 1200w. All of these PSU are worth there price in GOLD..You have a solid system do not throw all of that high end stuff with a cheap PSU. Also try BIOS 0511 seems to be the best one for me right now and some other guys with this board when it comes to OCing with a high FSB. Bios 0512, 0601 having problems at higher FSB settings..
