Asus P8Z77-V (Z77) Motherboard Review

Power Consumption

To test power consumption, we monitor the overall power of the system through a plug-in electricity usage monitor at an idle and load state. This allows us to show the fluctuation between how much power draw the system takes at idle and at load. By monitoring the overall usage of the whole system, it gives an easy comparison if you wish to do the same yourself as opposed to buying very expensive individual testing equipment.

One of the key aspects with looking at a mainstream board is the to-be-expected lower levels of power consumption when at stock speeds. Naturally the P8Z77 does just that and topping out at only 220W at full load is not bad going. Idle consumption is a little higher than expected, but sitting well below 100W is still highly acceptable.
