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 1 at 1920 x 1080 and recorded the peak power number while gaming a particular level that we test on each card. Our idle numbers are high, but keep in mind that we are using a workstation motherboard that has two 10GbE ports and other high-power draw controllers on it.
Power Consumption Results: With the ASUS Geforce GTX 1050 Ti 4GB ROG STRIX OC Edition video card installed in the system we topped out at 260 Watts when running BF1 at 1080P resolutions. The NVIDIA GeForce GTX 1050 Ti reference card uses just 75 Watts of power, so this is a really power efficient card.
