If you’ve got too many hard drives or other components connected to your computer, you may need a second power supply. In order to turn it on without connecting it to a motherboard you have to ‘jump’ it. It’s a really simple process – all you have to do is connect the green wire to any black wire on the 20/24-pin connector.
You can get a small piece of solid core wire (or a paper-clip) and poke each end in, get some proper ATX pins and connect them to a short piece of wire or, if you don’t mind permanently ‘damaging’ your PSU, snip the wires off, strip the end and either twist or solder them together.
That was easy, wasn’t it?
