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 1.10.1 at 1024×768 resolution. We also ran four game titles at 1920×1080 and averaged the peak results recorded the highest Wattage seen on the meter for the gaming results.
Power Consumption Results: With te XFX Radeon HD 7850 1GB Core Edition video card install in the system our entire platform used 101 Watts at idle, which is on par with most cards today. At full load we hit 293 Watts in Furmark and in the games we averaged around 265 Watts. Not bad performance numbers from a mainstream gaming graphics card and it is right where we expected the power consumption to be!
