Got a new EVGA 780 CLASSIFIED today, it requires 2x 8-pin plugs so I used the supplied adapter for one plug (2x 6-pin to 1x 8-pin) and for the other plug I bought a 4-pin molex to 1x 8-pin adapter but with it all plugged in the PC wont power up, soon as I take the card out of the PCIE slot it powers up.
I did have to modify the adapter I bought today as most of the plugs on the 8-pin side were square but a couple of plugs on the graphics card had little chamfers on them so I took a craft knife and added the chamfers to make it fit.
What could be causing the pc and card to not power up? Bios settings?
I can't see the bios without the gpu installed as the mobo does not have on board graphics! I can reinstall my old card if needed though to access bios.
