Power Consumption

Sapphire HD7950 Vapor-X Video Card

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.

Total System Power Consumption Results

Power Consumption Results: The Sapphire Radeon HD 7950 Vapor-X is a high-end gaming graphics card, so we expected to see fairly high power numbers. The results put the Sapphire Radeon HD 7950 Vapor-X at the top of the charts, but the power usage wasn’t that bad. At idle the entire system consumed 108 Watts of power and at full load we averaged 320 Watts in game titles. The power consumption is more than some of the other cards that we have recently tested, but not by much.
