Asus Radeon HD 7770 DirectCU TOP 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 is another area where this card performs well, with a low idle wattage of 122 and a load wattage just keeping under 200 watts. It goes to show that these custom cards are able to offer a little bit more, but don’t require mass amounts of extra power to do so.
