20 pin jumper

[whatdoiputhere]

Hello, I'm wondering if anyone knows where I need to put the jumper on a 20 pin mobo cable. If it's easier I also like to know if you can get a 20 pin to 24 pin adapter then jumper the 24 pin.

If the PSU only has a 20 pin ATX connector, you probably shouldn't use it. 

For the 24 pin ATX, the standard is green for the PS on wire. Short that to ground, any black wire.
