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 measured the peak wattage used by the system while running The Aliens vs. Predator full video game at 1920×1080 resolution.
Power Consumption Results:
As you can see, running at an idle the test system draws 132 watts of power, but once we get the EVGA GeForce GTX 560 SC in game and start playing at 1920×1080 resolution it spikes up to 308 watts; that’s a 176 watt difference from when the system is at idle. We are using a 750 watt PSU and that looks to be more than enough to keep the EVGA GeForce GTX 560 SC going with plenty of power to spare.
