AT Psu to ATX Mobo??

Sprye · 26-September-04, 12:58 AM

Ive searched and searched and only found an adapter for a ATX PSU to AT Mobo...

Wondering if there is any pinout info or even if it possible to Power a ATX mobo with a AT PSU

I came in possesion of an old dinosaur and want to throw some semi decent layaround gear I got into it to make an "old school" beast, overclocked , air cooled...and run Windows 3.11 .... I have no other hobbies.. hehe

An AT will not provide enough stable juice for an ATX rig. Yeah, it might be OK on the +12V but will suck on the +5 and +3. I use a couple of AT PSU's as test benches but would never think of trying them in an actual modern rig.

There are adapters for AT to ATX, but when you can get a great ATX PSU for $40, why?

Because I happen to have it laying around... /shrug

I do have a micro atx psu, and in the old case I might be able to squeeze it under the AT PSU...run them dual and use the AT for lighting and fans...

just brainstorming for ideas I suppose... I just came accross some old 386-486 gear I want to mess with.
