Hey guys, I just have a question about the power cables for my GPU. I have a Gigabyte GTX 780 OC with Windforce Cooling.

There are two 8-pin PCIe connectors on the card itself, but it says on the specifications it requires one 8-pin and one 6-pin connector.

My PSU has two PCIe (6+2) connectors on the same cable. I've already tried connecting a 8-pin cable into one of these sockets and a 6-pin cable into the other, but when I try booting up, it just gives me "PLEASE POWER DOWN AND CONNECT THE PCIe POWER CABLE(S) FOR THIS GRAPHICS CARD".

What should I do?

I have the Zalman ZM650-XG 650W 80+ Gold Power Supply.

Hi guys!
I know this is a closed thread but, I didn't want to open a new one to ask something related.
My problem is: I bought the GTX 780 OC windforce Rev. 1.0, and yes, it needs the 2nd 8 Pin cable. The thng is: I have one that came ID as PCIe and another generic one coming out of the PSU's body. It has 8 Pins and fits perfectly into the GFX card. I got it to start and it's running fine. My question is: is the PCIe cable specific for the job or can I continue using this second 8 Pin cable that was laying around hanging from my PSU? Will it fry my GFX card or will it be alright?

Thanks guys!
