An ATX to Bench Power Supply conversion, with a 10A max variable voltage output.
Easy to print. A bit harder to assemble the components inside due to tight space, but works well once that is done.
Be extra carefull when working with the ATX and high voltages! I take no responsibility whatsoever if you shock yourself, but please don't.
- Here is a mockup of the wiring: http://tinyurl.com/y34ol8ky
- I highly recommend cutting off the individual ATX wires and connecting 4 or 5 of them together to a single higher gauge wire instead for each output required.
- The potentiometer needs to be wire soldered and replace the existing "Volt Adjust" trimmer on the buck/boost converter.
- Two standoffs must be added on the bottom side (behind fan) of the ATX PSU case. These are needed to fasten the printed part on the ATX case.
- To avoid the power supply from slipping, I used double-sided tape on the bottom and attached some rubber mat I had laying around. Definetely not required, but it's nice to have.
You can easily remix/mod the left side cover to add extra stuff like USB or XT60 outputs if desired, without touching the base case part. There is plenty of space behind and the part is quite decoupled from the base case part.
