Power Consumption

Zotac GeForce GT 640 Zone Edition

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 1024x768 resolution. We also ran four game titles at 1920x1080 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 Zotac GeForce GT 640 had very nice idle power consumption and the entire system used just 98 Watts of power. At full load we hit 200 Watts and that was in both game titles and Furmark! This is around 90 Watts less than the GeForce GTX 660 and GeForce GTX 660 Ti, which is significant. If you don't need a mainstream or high-end gaming graphic card then something like the GT 640 will save you some money if it is used often.
