Hi there, I searched around for this and couldn't find a straight answer. I am just trying to upgrade my PC with a new graphics card, a 7970. It needs a 6 pin connector and an 8 pin. My PSU doesn't have an 8 pin available from what I can see. It has several 6 pins and several 4 pins. The GPU comes with two adapters, however. It has a 6 pin to 8 pin, and 2x4 pin to 6 pin. If I convert a 6 pin to an 8 pin, would that give enough power to run the card? Or how about converting 2x4 pins to a 6 pin, then converting that to an 8 pin with the other adapter - would that even work, and if so would that give more power? Would really appreciate help with this, thanks.
