Club3D Radeon HD 7790 13Series 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.

The higher acoustics indicate that the fan is running at a higher speed, which in turn draws a little more power to keep the card cool and this is reflected by the idle power consumption which is up a little when compared to similar cards.
