    I bought a Sapphire R290 Tri-X recently together with a seasonic 450 watt PSU.




    I plugged in the PSU, connected the 6+8 pin from the PSU to the GPU and replaced my old GPU , a 4870, with the R290.



    Now I don't get any video signal when I start up , and even after the start up (1-2 min later on) I dont get any video input!


    Is the card broken? Is my logic board broken?

    HELP!!!

    It's not support and there are no drivers for it. Return it if you wanted it to work with a Mac Pro.
