i just bought an ocz 520w powerstream power supply to power up my new system that i'm building, i'm putting in a 3.2g p4, asus p5ad2-e, ati x800xl, a dvd rom, dvd rw, a zip drive, a 160 gig barracuda, and about 5 fans going in an antec super lanboy case, will this be an adequate supply for what i need? i was gonna buy the pcp & cooling but i didnt have the extra $70.
