I'm asking because there is no such information in the manuals I have and there is no manual for my power amplifier (not provided from the manufacturer). Thanks.
On the back of each piece (usually near the power cord) you'll see the power consumption in watts of that piece. Add those up and you have your baseline #. No manual needed.
get a "Kill-a-Watt" meter for $20. Great handy cool little device, and easy to use. The P3/P4400 model will do you. Lots of places carry it. Amazon has it.
