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 Gigabyte GeForce GTX 1070 topped out at 281 Watts when running BF4 at 4K resolutions and that was ~18 Watts more than the reference card. Not bad considering the higher clock speeds and additional cooling fans. The idle power consumption was only 4W higher than the GTX 1070 FE, so they are basically the same.
