Hello, i have a xfx 7970 black edition gpu. when i was installing it i realized i dont have a 8 pin connector but i have a 6 pin (two in total) i need one 6 pin and one 8 pin. is there any other way to get the 8 pin because it says i cant connect 2x6pin to 1x8pin can i use 2 molex to one 8 pin the reason i am asking is because i have herd it can catch fire. my psu is xfx 750w pro core edition full wired. Thanks
