Hi all,

To power up my vintage MBs I have purchased an ATX to AT adaptor which works fine. However, I don't have -5V on it as all my ATX PSU don't have that rail. Everything seems to be working though.

Shall I assume that -5V was not a commonly used voltage even with vintage components?

Thank you!

No only a relatively small number of cards is using -5V.

There is a nice list in this thread - Re: ISA Cards & Devices Requiring -5V
