  1. wont be much at all...few watts like 10
  2. ^ agreed for wattage

    Some SATA CD-ROMs should just draw on the 5V line, but most (especially burners) will draw from the 12v line as well.
    I've heard rumor that some superslimline/green style devices will draw from the 3v, but I've never seen them.
    This is a good reference, but not 100% applicable
