HIS Radeon HD 7790 Turbo 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.

Whilst the acoustics are nice and low, the power ratings are not as low and this card consumes the most power under full load when compared to all the other 7790’s that I’ve seen to date at 224W. The idle consumption is also a little higher than average at 140W.
