  1. You can get a good estimate of power requirements here. Go with a 80+ efficiency 400W-500W PSU.
  2. yeah , but some reviews say that it is at least 500 watts..400 watts?
  3. Best answer
    ATI says the HD5850 draws up to 151W.
    What wattage did the power calculator show for the components you are using?

    I put in an E7400, 2 DDR2RAM, 2 SATA HDDs, 1 BluRay drive, 1 floppy drive, 4 USB devices, 4 LED fans, @90% load with 45% capacitor aging, and got 356W.

    If you want a 500W PSU, then by all means get it.
