MSI Radeon HD 7790 OC Edition 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.

At full load this is the most economic Bonaire card that we’ve seen yet, only just peaking over 210W, however we do note that it does use a slight amount more when at idle.
