[vcf-midatlantic] Old AT power supplies - how to test?

I have a couple of old DOS/Win98 (OS/2) era systems that I came across, and
they both have AT PSUs I want to check out before powering on for the first
I was thinking before powering on:
- Open the PSU
- Air spray the PSU
- Look for obvious signs of failure - capacitor leakage, burnt PCB, burnt
If all looks OK - do these require a load, or can I at least test basic
voltage with no load?
I do have heat resistors (used to balance out ATX PSUs for a 3D Printer)
that I believe I can plug in on the 5V or 12V rails and test voltage there..
How much testing should I do / what do you recommend?
