    I'm sure someone can chime in with more details, but you'll need a special power cable.

    It will go from the graphics card directly to the motherboard.

    Which end are you trying to figure out?

    Are you using an Apple supplied cable between the main board and graphics card?

    If not, then it won't work, as the 6 pin connector on the logic board is smaller than the one on the graphics card (not a standard PSIG 6 pin connector on one end).

    You can order them from here if you need to.
