I am building a system for a friend. The potential specs are like this so far:

  • ASUS A8N-VM motherboard
  • AMD Athlon 64 3200+ @ 2.0 GHz
  • Any 7200RPM SATA HDD
  • Palit GeForce 8800GT 512MB GDDR3 PCIe
  • One DVD/CD combo drive
  • Creative SB Live! 5.1 sound card

I was wondering what wattage of power supply would be able to support this hardware. I had a 350W in mind... would that do?

That power supply might be able to handle that hardware. I typical computer only uses 200watts or so.

keep in mind though that power supplies are designed to be most efficient at a fraction of the advertised wattage(not sure what the actual percentage is, 75% or so). so running a computer that actually uses 350 watts is a bad idea because it will put too much stress on the power supply.

THanks for your answer... I was using other wattage calculators that were way off the number given by that link. Much more accurate... thanks! –  Wesley Apr 1 '10 at 18:44
