AT power supply questions
Alright, I've noticed that my current power supply doesnt have enough 5.25 power connectors for me. So, my question is this. I opened the case and saw three different connectors running to my mobo, not 2. So, im wondering if there is any difference between a regular AT power supply and the one i have running in this funny intergraph system, what is the other connection? is it optional? Most of all, can I replace it with the AT power supply I've got collecting dust in the basement? is it an AT power supply at all?
