    Nice project. Here's a pin-out for the 20-pin connector ...

    The PWR_OK signal line (Pin 8) is how the motherboard tests If the voltages are OK and safe being delivered from the power supply. This is really a Go or No Go Tester. This idea is used by other authors ( cwebsterlus ) in their projects..... It could save time in finding a bad computer power supply. Thanks for your comment.
