Asus Radeon HD 7770 DirectCU TOP CrossFire 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 graphics card 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.

Keen to see how the cards perform when looking at the power consumption, we can see some load results the idle range and a good result at load with similar results to some of the more extreme 7950 cards which is on par in terms of graphical performance.
