The Hi Combo is rated at 1150 W on 220 V and 390 W on 110 V, but that rating reflects the AC heated bed at full power during warm-up. Once the bed is at temperature the printer cycles the heater, so the average over a whole PLA job is far lower. The defaults assume roughly 140 W for PLA including the CFS unit, rising for materials with hotter beds.
For the most accurate electricity figure, run a print through a plug-in energy meter and enter its average wattage. Your inputs are remembered in this browser.
