Power Consumption

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 1.9.2 at 640x480 resolution. We also ran the game HAWX 2 and looped the benchmark three times and recorded the highest Wattage seen on the meter. 

Total System Power Consumption Results

Power Consumption Results: The SAPPHIRE HD 7950 OC Edition video card does pretty well and it looks like we have a low leakage card here that sips the power as it does better than the other two Radeon HD 7950 cards that we have tested. The AMD Radeon HD 7000 series has impressive board power numbers and you can see what AMD claims below.
