This instructable is a quick guide to build a 20 pin computer power supply tester out of parts from old computers and PSUs. The tester will also work on power supplies that have the 20+4 pin connecter. You can use this method to make a 24 pin PSU tester as well. Similar units sell for around $15-$20 but you can make one for pennies if you have the parts laying around like I did. The inspiration for this came when my friend gave me his old dead tester after he bought a new one.
Step 1: Gathering the Materials
This instructable is meant to help save you money and keep people from wasting resources. All the parts I used (except the heat shrink) came from an old computer. This is just one of many things that can be built entirely from recycled components. I intend to use every piece of material from this pc. Every computer that goes bad i take apart and strip out all the working components before sending the rest off to be recycled or disposed of properly.
Be careful de-soldering! If you heat up the pins in the power connector too much it will melt and deform the plastic. I have unwittingly done this before.
button or switch (as long as it is not momentary)
2 wires (same length, however long you want it)
20 (or 24) pin connector socket
