I was taught that A multiplied by V equals W. Is it right?

The power is RMS, so you multiply by 1/√2 for sine wave AC current.

It looks like electronic engineers have a different meaning for the
word off than normal people.
When shutdown, the machine still has a small draw to keep the p/s,
PMU, part of the motherboard, and keyboard running.
It seems quite an ineffective

Nope, I connected the G5 directly to the power-meter with its own cable.
(measurement would have been pointless otherwise)

The display says W, thus Watts.
Using either the Kill-a-watt VA setting or multiplying the volts times the
amps results in Volt-Amps (VA).
