Let me start this off by admitting that I'm pretty much a newb to this whole computer building scene. I built a simple computer for a friend, but that's it. Now that I've got to building my own computer, I'm going all out (Athlon64 3400, 1.5GB ram, etc.) My question is about Serial ATA drives. My power supply came with two Serial ATA Power connectors built in. I have two serial ATA drives that I'm using... Do I need both the SATA power connector, the SATA cable to the mobo AND a 4-pin molex connector from the power supply? Or just the SATA power and the regular SATA? Thanks.
