Gigabyte GTX 660 Overclock 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.

On of the key points that NVIDIA highlighted with the 600 is its lower power draw, and whilst we have to take into account that this particular card is overclocked, what we have here is the lowest power draw at full load for a 600 series card that we have seen to date with a mere 242W at its peak.
