Yes. Going across the hot and ground well give you the voltage reading, just as if you were going hot to neutral. The neutral and gruond are connect at the main panel. To test if the outlet is properly wired, you would perform the test as listed in my post. Anytime I'm testing an outlet, I go across all three, hot to ground and then hot to neutral for voltage, then ground to neutral for continuity.

The shorter slot of the outlet is supposed to be the hot side of the circuit. The longer slot is the neutral. If you go ground to the short slot and get a reading then outlet is wired and grounded properly. If you get no reading between the ground and the short slot but get a reading between the ground and longer slot the outlet is ground but not polarized properly.

This test isn't that important in relationship to testing the PSU however, it's just some added info for piece of mind.

Alot of homeowners simply install the pronged outlet so they don't have to use adapters but don't actually ground the outlet. Again, this info may not be relevant to your article, but thought I would throw it out there anyway.
