How do you accurately measure how much current a PC is drawing at any given time? Do you have some kind of measurement device inline with the power cord?

Yes, I have one of those for my homelab. I draw about 200W on average, but it can spike to about 1000W.

You can use "smart" plug such as the Sonoff S31 (flash ESPHome to make it cloud-free).

		And for one-off testing there's the standard P3 Kill-a-watt.

Works good IME, but you have to plug it into the wall first. Sometimes if you plug the appliance in, and then plug the KAW in, it will miscalibrate

I have it plugged into a IKEA smart plug.
