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 1.25 amp resettable polyfuse. These four voltages cover many common electronics needs, there's even a negative voltage (-12 volts) for op amps and audio projects. 

An on/off button and a control circuit are included on-board, no modifications to the ATX supply are needed. 

  • -12, 3.3, 5, 12 volt supplies @ 1.25 amp
  • 1.25 amp polyfuses with reset on each power rail
  • Indicator LEDs show that each rail is working
  • Power good and enabled indicator LEDs
  • On-Off button and control circuit
  • Optional load resistor included but NOT soldered
  • Open source (CC BY-SA)
Note: A 9 Watt load resistor is included but not soldered to the board. 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. Please let us know your experience.

Some special ATX supplies provide -5volts, but the vast majority don't. We broke it out and added the fuse, but didn't populate the screw terminal.
