Sapphire Radeon HD 7770 OC Vapor-X 1GB Graphics Card Review
Andy Ruffell / 12 years ago
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.
Moving to the power consumption, the 7770 card isn’t exactly power hungry, and we see that the overclock has only pushed the load wattage up by 2 Watts, while the idle is slightly higher compared to reference speeds.
