Gigabyte GeForce GTX 770 OC WindForce 3x 2GB 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.

As expected with any overclocked card, the full load power consumption is up in relation to reference power levels, with an extra ~30w needed to give the card the power it needs.
