    Need to figure out which Power Supply to buy?

    http://users.erols.com/chare/elec.htm

    IMO, this should be a sticky. Also, most of those power ratings are PEAK. Actual operation values are lower (from my experience...approximately 25% lower).

    General Rules (please add to the list or suggest modifications) culled from various power consumption websites:

    Motherboard:+ 25Watts
    3.5" HD: +15 Watts
    2.5" HD: +5 Watts
    Optical Drive: +15 Watts
    USB Device: 5 Watt/each (Very HIGH estimate...personally, I would go with 1 Watt/each)
    Various Graphics Card: ???
    Various PCI Sound Cards:???
