How to Turn on a Computer Power Supply without a Computer

ATX computer power supplies are readily available and cheap. They provide a easy way to get 12 volts or 5 volts DC. In this video I show you how I turn on the power supply without it being connected to a computer.

Some power supplies won’t turn on without a load on its 5V rail, so you’ll need some sort of load like the light bulb you have in the video, or a power resistor to draw a bit of current.
