    Hi,

    Maybe someone here can help me.
    I have a dual CPU 8 core Xeon mac pro. 16 GB mem.

    I just bought the ATI R9 270 OC card edition from gigabyte.
    I also bought the 2 special power cables that I needed (from main board to 6 pin power cable to power the card).

    Installed my card, connected the power cables, but nothing,...
    No screen, even after 5 min, nothing happens on my screen.

    Anyone with some suggestions?

    BTW, yes I installed a 64 bit boot loader, and I am running mavericks.

    You need to add device ID to drivers, exactly that same like was with 7850.
