Thanks to everyone pointing me to articles on ATX power supplies as bench supplies. Mine is a very oldAT supply, but I'm hoping that the same principles apply to it.

I'm sorry for the off-topic question, but can't find a good reflector for this one, and I figured this diverse group was most likely to have answers. Please feel free to reply off-list.

10-plus years ago, I built what was to be a bench supply using an old AT power supply - 5 and 12 volts. It didn't put out any voltage, so I shelved it - figuring a bum supply. Then just a relatively few years ago, I read that these supplies required some load on the 5V supply in order to put out any power on either output. I can't find the reference now, and am hoping some of the knowledgeable here will have some info on this.

Thanks for your patience
