For testing power consumption, we took our test system and plugged it into a Kill-A-Watt power meter. For idle numbers, we allowed the system to idle on the desktop for 15 minutes and took the reading. For load numbers we ran three games at 1920×1080 and averaged the peak results seen on the power meter.
Power Consumption Results: With the NVIDIA GeForce GTX 760 2GB reference card on our test system we observed a 100W idle power draw at the wall outlet and when gaming that jumped up to 336 Watts. This is on par with most other cards at idle and the peak power draw was near the bottom of the chart, so this card is fairly efficient all things considered.
