I am replacing an old power supply (noisy). The motherboard is an Asus P4P 800 Version 2. It uses a power connector 20 and a 4-pin connector of the CPU. Of course that was removed from the 4-pin 24-pin connector, and separate from the CPU pin 8-4.
Stripped the system on a memory stick, video card simple. Connected only 20-pin and 4-pin PSU. I have the LED board, press the power button, all the fans, etc, come on, but then do not. I put the old power forward again with only 20-pin and 4 pin connector and mail well. rear and forth, the identical performance.
It behaves as if the 4 pin CPU is bad? Both connectors snap into place and remove the post unless you activate the release. Suggestions? I know it can only be connected in the correct position of 4 pins, as they have correctly.
