Ten years ago I attempted my first computer power supply repair. For the next ten years, it has become a hobby. I went to several computer shops asking for dead computer power supplies, and received many. I can still remember the first computer shop I visited. A salesman asked if he could help me. I said I was looking for a computer power supply. He asked what kind. I replied one that doesn't work. The look on his face was priceless! I suppose many on badcaps have a large stash of power supplies. So here are some pictures of my stash which I keep in the attic.
My first computer power supply repair was a Bestec ATX-250 12E, the famous mother board killer. After several unsuccessful attempts at repairing the 5vsb circuit, I gutted the circuit and replaced it with an outboard DM311 chip circuit. I had no way of knowing what a controversy I was starting by posting the repair on badcaps. Until then, everyone thought the 12E was trash, not fixable and reliable. I think most have now come to a consensus that the 5vsb was the major problem with this power supply, and once the circuit is modified, the 12E is built like a tank. It did need some old wimpy capacitors changed. That original repair is still powering a computer in my garage.
So......if repairing computer power supplies has become one of your passions, how about sharing some pictures of your stash.
