Shorting a PSU
Here's a tip that any PC builder can use. You can test the PSU of your system without running it through your motherboard. You can do this before installing it to make sure you didn't get a faulty part.
- Plug your PSU into an outlet with the power switch OFF. - Take a paper clip (or something of that nature) and unfold it. - Take the unfolded paper clip and on the 20/24 pin main connector, place one end of the paper clip into a ground pin (black) and the other into a power on pin (green). - Flip the switch on the back of PSU to ON. - Your PSU should turn on with no problems.

Me thinks you should edit the first line to include "With the Power Switch OFF."

You should really also plug in a fan or old hdd to give the PSU a load, some don't turn on unless there is a minimum load applied.

True. I use it a lot to test my liquid cooling system after cleaning it and such. It's really useful for that application since I can set it up to only give power to the liquid cooling system.

You can also you this trick to use an old power supply to power external fans or an external watercooling system.
We use it at work to power 12V rack fans (for home theater/home automation). A basic power supply can source 15A and costs less than a 2A wall wart style 12V power supply. We also use them to power 12V camera systems with lots of cameras. |

You don't even have to use the paperclip trick for that kind of use if you use an old AT power supply.
