ATX bench PSU

This project converts an old ATX PSU in to a bench supply with variable power out put.

They are pretty easy to source from dead office pcs. 

For a better fit I would recomend cutting of all wires you dont need. Also if your PSU has a power switch, you can solder a wire across 2 pin on the breakout board to start the PSU when you flip the switch. 

You will need the following parts:

4x PSU screws

4x m3 20mm  screws

4x m3 heat inserts
