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 OpenGL benchmark FurMark 1.9.1 at 640×480 resolution. We also ran the game HAWX 2 and looped the benchmark three times and recorded the highest Wattage seen on the meter.
Power Consumption Results: The MSI R6950 Twin Frozr III 1G/OC video card turned out to be fairly power efficient compared to the other three video cards that we compared it against. The AMD Radeon HD 6950 used the least amount of power when running Furmark at 640×480 and HAWX 2 at 1920×1080! The idle Wattage was on par with the other cards as well
