I recently started making my own benchtop power supply out of an ATX power supply I got off of ebay. I quickly took it apart, and grounded the green wire. The PSU stayed on, and I confirmed there were the proper voltages going to each lead by using my multimeter.
Yesterday I ran into a problem. I cut ALL of the leads, grouped the grounds and power leads seperately isolating them using electrical tape and zip ties. I also combined the leads I wanted to use, and soldered the green wire to ground.
Now, the PSU stays on for a split second, and then turns off. I confirmed this with a quick voltage spike from the leads when turned on, while quickly returing to 0V. Fan does the same thing.
This is absolutely mind boggling to me because it seems I haven't changed anything, just reorganized wires. And now it wont stay on. Any ideas what could be wrong or where I could check?
