I just bought an Evga 7900 GT CO from newegg and the first night of using it, everything was absolutely beautiful. Then the next morning I boot up and I get a Nvidia message saying that the card's preformance was lowered because the power is not sufficient. So I read the manual and I realize I stupidly forgot to plug in the cable (shown in the picture) from the card to the PSU. The only problem is, I don't know HOW to plug it in. When I plug it in incorrectly, which means every single time, the monitor goes black and refuses to send me to the desktop. As you can see the cable has two white adapters at the end, but there are 3 white adapters that come from the PSU, so I don't know which 2 to use. Should I even be using both of the adapters from that cable?
