Sapphire Radeon HD 7770 Overclock Edition 1GB Graphics Card Review
Chris Hadley / 13 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.
In respect to the reference card we naturally wasn’t expecting the same low power figures at idle and load but when we’re seeing this card perform in 6850 territory almost consistently, we note that it uses around about the same power as well.
