A friend of mine wanted me to look at his old computer to try and fix it. While looking in the BIOS I noticed the PSU rails going nuts... so I said oh well.. PSU's broken!!!

But ... it's an old computer.. and I counted 12 pins for the power supply... so this is a problem obviously!

Since he doesn't want to change the computer..is there a website that still sells 12 pin PSU or is there a way I can take an existing 20 pin PSU and just plug in 12 pins?
