converting old power supply

Here is a link that shows how to convert an old power supply so you can run fans, small moters or whatever you need to test. I built one in my basement to run both my built-in car sterio and a way to test fans and other stuff. I hope you find this usefull.

What about using an old AT style PSU? Do you still need a load resitor?
