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 Battlefield 4 at 3840×2160 and recorded the average idle reading and the peak gaming reading on the power meter.
Power Consumption Results: The EVGA GeForce GTX 1080 SC in our test system used 99 Watts at idle and 342 Watts at peak 4K gaming. This is the same exact idle numbers as the Founders Edition model and slightly more at load, which makes sense due to the higher clock speeds.
