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 entire platform with the NVIDIA GeForce GTX 780 Ti installed was consuming 106 Watts at idle and hit a maximum of 474 Watts when gaming. This is 69 Watt or 17% jump in power consumption over the GeForce GTX 780 and puts the GeForce GTX 780 Ti at the top of the chart for power consumption. If NVIDIA would have released this card before the GTX titan and Radeon R9 290/290X were released it would have been considered a power hog as it consumes ~100 Watts more than the Radeon HD 7970 and ~120 Watts more than the GeForce GTX 680. Now that the Radeon R9 290X has been released, the NVIDIA GeForce GTX 780 Ti power consumption looks okay as it is just 10-20 Watts more!
