I was pretty stoked about it and hooked everything up exactly as i did before with my 850 watt psu. when i plugged in the psu, my EVGA z68 FTW board glowed blue showing me that it had power. When i hit the power button, the orange light showed up as it usually does when it posts but after that...nothing! No fan spins, no post codes, no nothing. i'm pretty depressed right now and am wondering if perhaps this 1300 watt psu is bad? i don't think i have a grounding issue in the case. this is depressing! ;/ i7 975 Extreme 4.4ghz @ 1.4volts Evga x58 SLI motherboard Evga 780 GTX 3gb SLI G.Skill 12gb DDR3 @ 1600mhz EVGA 1300 watt G2 PSU #1 12 Replies Related Threads

The VGA ports and wires are wired differently and will prevent it from POSTing. Please note that two 8pin power connections is only required if you are doing extreme overclocking so you can run the board with only one attached. #6

Please note that two 8pin power connections is only required if you are doing extreme overclocking so you can run the board with only one attached. the cpu wires that came with this psu are only 4 pin. could i place two 4 pin connections into one 8 pin plug? i wasn't sure of that to begin with so that's why i used the 8 pin vga cables. >.< i'm sitting at the nurses station right now, wishing i could try this out. can't wait til i make it home! i7 975 Extreme 4.4ghz @ 1.4volts Evga x58 SLI motherboard Evga 780 GTX 3gb SLI G.Skill 12gb DDR3 @ 1600mhz EVGA 1300 watt G2 PSU #7

Yes, the 2x 4pin squares fit together to make an 8pin for the CPU power. Some older motherboards boards and very small motherboards still just have connections for a 4pin so this is why they are split. #8

I'm sure it will post just fine...but if not, I'll come back crying to you guys. I was always just weary of combing two connectors to fit one plug. Always seemed fishy. But i can see why you guys designed it that way to be able to support that many more boards. Thanks a bunch guys!
