good? no. i recall CWT made a 550w or 600w PSU for bestbuy/rocketfish that was decent but I'm pretty sure the 900w is a huntkey made unit. are you looking to spend $50 on a PSU or do you need one that can provide 900w? if it's the latter, what are your specs?
my spec are amd phemon IIx 4 840 mobo asrock n68-s3 gpu gtx 560 4gbs of ddr3 ram
