Can ATX power supply work when mounted upside down? Its 300W
(Chaintech) but with small load (Amiga 2000).
I understand your concern. I have a 350W Antec whose normal mounting
arrangement has the PCB upside down. In addition to the obvious
heating issues, there is an intake fan at the bottom of the case which
blows additional heat from the nearby CPU through the PSU and out via
the exhaust fan. Not an advisable setup IMHO.

The power supply fan is part of the case cooling system; it's not just
to cool the PS (if it were, the intake would be outside the case).

A typical ATX case cooling system has case fans. These fans should
exhaust waste heat from the CPU, not the PSU.

They both do.
