So I was diagnosing my sisters old PC that has a micro ITX board in it.
I troubleshot the PSU and it didn't seem to be the culprit at the time. So I ordered a new identical board. When I hooked everything up it still didn't boot, so I fell back on it must have been the PSU after all. So I installed a new PSU and it still would not boot (either board).
I found a totally different PSU and used an adapter, and it managed to boot up the old ITX MB.
So my first guess was the new PSU was DOA, but... I plugged it into another separate ATX MB unit and it booted that PC up with no issues.
So I am at a loss as to why the PSU won't work with one MB setup, but works with another... and why a separate ancient PSU boots up the ITX board with no issues.
