Power Consumption

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.

Video Card Power Consumption

Power Consumption Results: The EVGA GeForce GTX 780 SC w/ ACX Cooling has pretty insane power numbers and was actually more energy efficient than the NVIDIA GeForce GTX 780 reference card. This caused us to look a little deeper and we discovered that the EVGA GeForce GTX 780 Superclocked has a vBIOS with different voltage settings than our reference card.  The NVIDIA GeForce GTX 780 reference card idles at 875mV and the EVGA GeForce GTX 780 Superclocked idles at 861mV. These voltage differences and the different cooling fans are likely the reason there is a power difference and it just happens to be in EVGA’s favor this time around.
