Testing an IBM power supply from an old IBM PC (51510 / 5160 / 5155) without it being connected to the motherboard is not trivial.
I had read online that the IBM PSU won't start if there is insufficient load on it, and adding a hard drive or a fan is simply not enough.
I decided to put this to the test, and see what was needed in order to start the IBM PSU.
