Asus Sabertooth 990FX AM3+ 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.

In both idle and load tests, the Sabertooth seemed to use a bit more power than the Crosshair, but though this may initially seem bad, it does show that Asus have been working to keep power draw as low as possible whilst implementing new features. This actually shows that the Sabertooth is the better board for power consumption due to its increased features, yet similar power draw.
