XFX Radeon HD 7770 Black Edition Overclocked 1GB Graphics Card 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.

Power consumption wise, we see the card falling inline with the other cards from the 7770 series with the power just peaking above 200 Watts in load conditions.
