Well I don't have the specs on the powersupply right now. the processor is an AMD Athlon XP 2800 and the motherboard is an Abit NF7-S nForce2 Athlon XP. I know that I specified to the person buying the powersupply that it needed to be more than what I needed. I didn't want to skimp on it. :/ Thanks again for any help you can give me.
