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 1920×1080 and recorded the average idle reading and the peak gaming reading on the power meter.
Power Consumption Results: The Gigabyte GTX 960 G1 Gaming SuperOverclock and the ASUS STRIX GTX 960 DirectCU II OC 2GB video cards both topped out at 236 Watts in the scene we test on. At an idle the G1 Gaming card constantly bounced around 102-104 Watts, so we averaged out the reading to 103 Watts, which was just 1W more than the ASUS STRIX OC that was pretty dead flat at 102 Watts when in a 2D idle power state.
