frys usually has varying stocks. the antec i posted is on their website:http://www.frys.com/product/6165899
last time i was there they had a bunch of coolermaster and some antec parts. just look for something in the $50-80 range with about 500-750 watts with a brand like antec, cosair, seasonic, xfx, and try for at least 80+ efficiency or 80+ bronze. typically those with those efficiency ratings are gonna be higher quality.
