Hey there- I'm thinking of upgrading from my P3-700@903 to an Athlon 1.3@whatever. I've never had much concern about my PS before. I think it's 250W. Will this be able to run the Athlon+Gefork2+dvdrom, cdr, 3 hds, sbilive5.1, ethernet, Miro video editing card, dvd decoder, floppy, and a couple fans + CPU fan?
