I just bought a Pentium D 820, mobo Asus P5LD2-VM, XFX GeForce 6600 GT 128MB, 1GB Corsair DDR2, M-Audio Audiophile 2496 ...spent all my money on that, so I´ll buy the case and HD later on...for now, will use the ones from my old P3 1Ghz...anyway, the power source I need to buy...I was thinking about the SevenTeam 420 BKV...do you think that real 420w will be plenty? Thanks!
