The following article is nothing more than a project report. I take no responsibility for how others may use this information.
I have seen many reports of people using standard pc power supplies to power their chargers, so I thought I would give it a try.

What I used for this project I used a handful of tools to convert my unit, including a soldering iron, drill, pliers, cutters, multimeter, etc, with no special tools required. I had an older, retired power supply sitting around the office, so it became my guinea pig. Beyond that, all I needed was some case mount banana plugs and a load resistor, so the project definitely didn't break the bank. The conversion process Below are the basic steps I followed to convert my unit and it took me about an hour to complete.
Once I was finished and had everything tidied up, I replaced the cover and tried it out, and it worked great. Notes and such
| What I used ![]() Opening up the PS Getting my bearings Trimming the wires Installing the load resistor I used 2x 1.5ohm 10W resistors in series for a total of 3ohms Mounting the banana jacks This PS allowed me to use some wire cutters to make the holes for the banana jacks. That saved me from having to drill the holes. Connecting the green wire to a ground wire and tidy up That's it, my converted pc power supply |
