Power Consumption
For testing power consumption, we took our test system and pluggedit into a Seasonic Power Angel. For idle numbers, we allowed the systemto idle on the desktop for 15 minutes and took the reading. For loadnumbers we measured the peak wattage used by the system while runningthe OpenGL benchmark FurMark 1.7.0 at 1920x1200 resolution.
Power Consumption Results: The Sapphire Radeon HD 5870 Vapor-X uses the same amount of power as the reference designed ATI Radeon HD 5870 does at idle. At load, though, the Sapphire Radeon HD 5870 Vapor-X uses slightly more power, which is likely due to a voltage bump for the overclock and the larger, more powerful 92mm fan that is being used.
