3D Model: ATX Breakout Board v1.1

Today’s 3D model is the recently released ATX 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 1.25 amp resettable polyfuse. Check out the video release as well.

Available for $13.80 at Seeed Studio.

Check out our tutorial on how to build 3D models from Cadsoft Eagle board files, as well as the tutorial on how to render life like images with Kerkythea.

The models will be published in the Dangerous Prototypes 3D warehouse collection. They are also uploaded to our SVN. You can find them inside the “art” folders in the respective project folders.

  1. That’s absolutely non-realistic: the power switch should be vertical, non right angled! :P
    Just joking off curse, awesome rendering as usual!

  2. Is it reliable to connect the various 3.3 volt supply outputs together? I know there are some issues when using two supplies together in parallel so they share the load equally but don’t remember the details. Maybe the ATX supply really has one 3.3 output and you’re just bringing them together again..

    Just something to think about.

    1. on the same ATX cable they are connected to the same 3v3 line, same for 5v, and 12v….
      now 12v lines on some ATX supplies are separate, but all the pins on the ATX jack that are 12V are all connected to the same line, the other v12 lines are used for the cpu jack, and the Graphics card jacks…..

      so to sum up…all the pins on the atx jack that are the same voltage are connected together directly in the PSU, so it is safe to connect them afterwards as well..

      now if you have 2 PSU with 2 ATX_BB it’s a bad idea to connected any lines together in parallel…even worse is to connected them in series (3.3+3.3=6.6) this will result in a short circuit, as computer psu’s are grounded so both PSU’s GND lines are connected to each other…
