A basic electricity meter shows my machine draws about 250watts for both Y and X together under normal use, but the meter will not show peaks (then again PSU caps should supply peak current draw).
500W will run all the axis no problem.

Also the ESS works fine with Slaved axis and homing. The install time is minutes with no rewiring required. Just install plug-in and away you go.
You may want to retune the motors for better performance.
