Thank you both for your responses. I have the published specs on all of my components.The thing is, I don't believe them.The P300 will give you a readout of power consumption of the components plugged into it. My Pass amp is supposed to draw 200 watts at idle, but if I run it and my front end stuff into the P300, the reading is about 190 watts. And then what is the P300 itself drawing from the wall? Some of the reviews of the PS Audio Power Plant P300 have stated that the unit draws 300 watts all the time, but PS Audio says this isn't true. So the reason for my question is to try to get a true measure of what's going on here. Bob, your solution is too tricky for me to attempt. I'll tell you, if someone could devise an in-line meter for this, I think it would be a useful addition to my audiophile toolkit. -Dan
How can I measure power draw?
Is there a simple way to measure how much power my components are drawing from the wall? My interest is prompted by experimenting with the PS Audio Power Plant and various conflicting info about how much it draws. (The answer I'd love to get is that there is a Radio Shack box I can stick in between the DUT and the wall, but you tell me...)
