Sapphire Radeon HD 7750 Ultimate 1GB Graphics Card

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 of the card showed at idle, a low 101.1 Watts due to the passive cooler. At load, a remarkably low 141.7 Watts was used, due to no extra power needed for an active cooling solution.
