Biostar TZ77XE4 (Z77) Motherboard Review

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.

Lastly, taking a look at the power consumption of the whole system, including graphics card and other vital components, we find the Biostar board giving the higest readings for idle power consumption, and sitting on the higher end of the scale at load. When overclocked, the system boosted in power usage, with the idle sitting over 100 Watts and load sitting at close to 300 Watts.
