Assuming your domestic power consumption meter either has a rotating dial or
a neon/LED that flashes to show electricity consumption and also stated on
the meter what 1 rev or 1 flash means in terms of power consumption.
Turn off everything electrical and count flashes or revs in one minute when
you've plugged in your kit and multiply.
If you don't wish to turn off stuff with clocks then time with this base
load and then re-time with your offending kit plugged in , take difference
and multiply.
As a rough rule compare the heat given off by each with a 15 watt mains
bulb, and even more general the ones giving off the most heat are likely the
biggest consumers of juice.
