Sapphire Radeon HD 5830 Xtreme 1GB Graphics Card Review

Power ConsumptionTo 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.

Taking a look at the power draw from the whole system when comparing against other cards showed some reasonable numbers at idle and load with nothing out of the ordinary in regards to its position between other cards.
