Yes. Most standard atx ps will work on all new boards. Antec, corsair, and ocz are good brands. Go for a bronze ps if you need to save some money. A 650w should be around $75 after rebate. 750 maybe $15-20 more.
Ok so just to be sure even though my motherboard says 24 pin power connector I can use a PSU with that says the connector is 20+4 pin?
