... it depends upon how accurate you want to be and how much power. for my system it was a simple matter of buying a reasonably sized battery backup unit which includes in it's display the amount of power being drawn in watts. on sale the backup unit cost about $150 USD. if i want to see what something draws i have a power cord set up to use for that and just plug it in and watch the display as it operates. if the device is a computer part i can plug it in to my motherboard or via usb or ... as long as it gets done with a grounding strip and i do the power turn off and turn back on as is appropriate for the device (and within ratings of my power supply). also use this setup to figure out how much power the various wall warts are eating. :( switches on all of them are worth the expense. songbird
