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.


Power Consumption Results: The NVIDIA GeForce GTX 780 is basically a GeForce GTX Titan with half the memory and fewer enabled CUDA cores, so it shouldn’t come as a big shock that it uses less power at load. The difference isn’t significant, but it is measurable. Just because NVIDIA has disabled cores in the GK110 ‘Kepler’ GPU doesn’t mean that they are no longer powered, so that is one of the reasons that the power draw is so similar.
