    I have a DC-DC 200W power supply that likes to take 12V (plus or minus
    1V). Finding that an XBox 360 adapter yields 203W 12V I set about
    hooking it up to the power supply and it works.

    The xbox cable has three 12V connectors and three grounds. I only
    hooked the PSU up to one of each. Should I be getting all 203W thru
    that one connection?
     
  2. I would have to see or reconstruct a schematic of the of
    your Xbox supply to know for sure. But I would be concerned
    that a single pair of conductors are not rated for the
    current your converter will draw (200W/12V=9.5 amperes, at
    least).

    You probably can for a while but the contacts are rpobably going to overheat.
    Use all the contacts.
