Asus GTX 660 DirectCU II 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.

Like acoustics, power consumption is important and the 660 at load uses around the same total power at the 660 OC from Gigabyte, however at idle we find a draw of only 125W from the entire system.
