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 770 doesn’t appear to use more more power than a GeForce GTX 680 despite having a higher TDP. The MSI GeForce GTX 770 Gaming OC actually used less power at idle and load than the NVIDIA GeForce GTX 680 reference card.  The ASUS GeForce GTX 770 DirectCU II OC used more power than the MSI GTX770 and the NVIDIA GeForce GTX 680 reference card though. The ASUS card uses 10 Watts more power in games and 8 Watts more than the MSI card due to the design of the board and the PWM components.
