hi there, i recently brought a 9800 gx2 for cheap but wanted to try it in my pc to see if it actually works. ive got a asus maximus v gene mobo and a tx750m power supply. so i connected it up but the graphics card requires a 8 pin and a 6 pin, i only connected the 6 pin. powered the pc up and it didnt turn on but i heard a little sound on the power supply and say a little spark. Me thinking the power supply dont work any more, i want a got a new one. got the CX750m, connected everything up with my normal cards (2x 6870s (CF), PC still dont turn on. What is the problem. Plz HELP
