Power Consumption & Temperatures
As expected the Radeon HD 7990 consumes roughly as much power as a pair of Radeon HD 7970 GHz Edition graphics cards. Total system consumption was 491 watts, which is 22% more than the GeForce GTX 690 and 36% more than a single 7970 GHz Edition card.
Compared to graphics cards such as the GeForce GTX 690, GTX Titan and even the 7970 GHz Edition, the 7990 ran quite cool. Temperatures never exceed 72 degrees, which we consider very cool for a high-end graphics card.
