    Description

    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.


    Features

    • -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.

    Nice for the price
    The only faults I can find with this so far are that the power resistor that is supplied with the unit does not fit inside the acrylic case that Seeed supplied me... so in the unlikely event that I'd need to use it I'd have to either cut the case, get longer standoffs for the lid or find a different resistor - and secondly I have a couple of power supplies that have the longer ATX plug - which needs to be physically attacked with a dremmel to make them able to be plugged in... maybe using the longer socket would alleviate this.

    If you have the perspex cover and need to use the resistor, just solder the resistor onto the bottom of the board and use standoffs that are long enough to give clearance.

    Thanks for your suggestion, but there's no perspex cover for this version.Thanks.
