ATX Power Supply Breakout Board
Recycle an ATX computer power supply into a beefy bench tool that powers your projects. The ATX breakout board routes the -12, 3.3, 5, and 12-volt ATX outputs to screw terminals, each protected by a 5 amp fuse. These four voltages cover many common electronics needs, there's even a negative voltage (-12 volts) for op-amps and audio projects.
We have a super cool block post on how to build a bench power supply with this module: DIY bench power supply using old PC power sources
An on/off switch and a control circuit are included on-board, no modifications to the ATX supply are needed.
ATX breakout board Features:
- -12, 3.3, 5, 12 volt supplies @ 5 amp
- 5 amp fuses on each power rail
- Power enabled indicator LED
- On-Off Switch and control circuit to shut down entire Power Supply
Note: A 5 Watt around 10-ohm load might be needed. Some ATX power supplies require a load on the 5V rail to start up. In our experience, most modern ATX supplies don't require a significant load on the 5-volt rail to start. An artificial load just wastes electricity and creates unnecessary heat.
