PCI-e: Not sure how to connect graphics card to power supply

I have just purchased an EVGA GeForce GTX 680. I plugged it into the PCIe slot and now need to connect to power, but I have a small problem.

The card comes with an 8-pin splitter that connects to two points on the card. The PCIe power cable from my supply looks as though it can be 6-pin OR 8-pin, depending on the needs. I first want to confirm that I am right in my evaluation and secondly identify how to connect this to the 8-pin adapter. I have included pictures of both the cable from the power supply and the adapter to connect this to the card.

  2. Best answer


    You just need two of these, that is 2x(6+2 pins)
  3. Thats a wierd splitter? Never seen on like that. But yes the pcie power cable in the first picture can be used as a 6 or 8 pin and the other two pins can only lock in one way. You shouldnt need that other piece if your power supply has two 8 pin pcie connectors. Just force them in there they can only go in one way
  4. Thanks for the help. I did not realise there was only one way to do it, but that photo is a heck of a lot clearer than real life. They should make them that big in the first place :P

    My power supply has room for two 8-pins, but only one is currently in the system. Guess I will need to pick up an extra cable, but that is easily done.

    what I need to run from my power supply to the video card via the PCIe socket in said power supply (a SeaSonic)?

    If not, would the correct cable be called a PCIe Power Cable rather than VGA?
