So far I have everything completely in place but when I press the power button the computer tries to start and turns off. I have the 8 Pin connected from the CPU to the Power Supply and it still doesn't work. The motherboard does turn on with the LEDs and everything. HELP!!!
Make sure the cable is well seated at both ends.
Try a different 8-pins power cable, and connect that to the PSU and to the motherboard. It is possible that you may have a defective cable.
Also, try a different 8-pins power outlet on the PSU.
