Hi - I'm working on a Gateway PC with a Pentium 1st-gen board on it (LX chipset). I would like to try a newer power supply, but new AT ones are difficult to find, and the few I've seen have power cables too short for this tower, so I was thinking of using an ATX PS with the adapter you can find that bridge the needed 20 port ATX voltages to the AT connection. However, most ATX power supplies (and all the ones I could find) lack -5V, which is on Pin 9 of the AT connector. I've been seeing mixed responses on whether it's needed, so I figured I'd ask the experts here. My board has PCI and ISA slots, it's the 'Batman' Intel board. Thanks as always for your help.
