ATX Breakout Board bench-top power supply build


Kevin Rye shared his ATX breakout board bench-top power supply build in the project log forum:

It took 3 weeks for my ATX Breakout Board to arrive from Seeed, but I finally got it! I was so excited to finally be able to make a bench-top power supply. I’ve always wanted one, just never got around to buying one. They can be so expensive. I figured for the $15 bucks the breakout board costs, I could just make one with an old ATX power supply.
Here’s the 250W ATX Power Supply from an old Dell that kicked the bucket. More than enough juice for the average Arduino project.

Via the forum.

You can get one for $14 at Seeed Studio.

  1. Sad but true – bench-top supplies are still priced as if they were made from solid unobtainium. Anyway, nice rig – the wires could be routed in a bit more orderly fashion, but it’s no biggie.

  2. Convenient, but modding the PS, adding jacks, and then being able to use the full rated output on any rail was my path.
