    So i bought a ASUS GEFORCE GTX 750ti from New Egg

    So i am comfortable taking out the old video card and install ing the new one in the bottom bay where the current video card was. I am currently running El captain

    The one thing that worries me is that it didn't come with a 6 pin adapter but from what I have read about this card is it does not need to be connected to the power supply.

    So before i removed my current video card I downloaded the most up to date firmware and confirmed that the computer is going to boot with the NVIDA Web Driver.

    Are there any other trouble shooting things I could try?

    Thank you in advance!

    I would have a chat with new egg about why the cable was not supplied with the card,
    ALL new cards come with the cables, it should have been in the box with the card as well as
    a DVI to VGA adapter and the SLI bridge cable (if the card is SLI capable).

    Is the 3,1 also use mini 6pin? If yes, there is no card come with that cable (escept the two official Mac Edition card). Ask new egg won't fix the issue.

    All Mac Pros use that mini 6pin PCIE connector and only Mac Edition graphics card will include that cable. For all other ones, you'll have to buy one separately.
