    Would it be possible to get a PC 5770 graphics card to work on a 2009 Mac Pro if the card needs a 6-pin power cable?

    I have not seen a 4-pin on the graphics card before. Are you sure it's not a six pin on the graphics card?

    The 5770 almost certainly needs a 6-pin power cable but there are some twin 4-pin MOLEX to 6-pin GPU cables that were used. Normally since the Mac Pro already has one or even two 6-pin cables you should just be able to use those.

    If you buy a genuine Apple 5770 card it should come with the correct power cable.

    If you buy a PC 5770 as you state, you will need to purchase this power cable. Also unless you flash it, you will be missing several features, most notably boot screens.
