VGA Power Consumption
Life is not as affordable as it used to be, and items such as gasoline, natural gas, and electricity all top the list of resources which have exploded in price over the past few years. A high-end graphics card under load will use more power than any other component in your computer, and frequently more power than everything else in your computer combined!
To measure isolated video card power consumption, Benchmark Reviews uses the Kill-A-Watt EZ (model P4460) power meter made by P3 International. A baseline test is taken without a video card installed in the test computer system, which is allowed to boot into Windows and rest idle at the login screen before power consumption is recorded. Once the baseline reading has been taken, the graphics card is installed and the system is again booted into Windows and left idle at the login screen. Our final loaded power consumption reading is taken with the video card running a stress test using FurMark. Below is a chart with the isolated video card power consumption (not system total) displayed in Watts for each specified test product:
* Results are accurate to within +/- 5W.
At idle, the EVGA GTX 275 CO-OP PhysX Edition uses 55 watts of power. With the GTX 275 GPU under load in Furmark (and the GTS 250 idle), the power consumption rose to 247 watts. Stressing the GTS 250 with Folding@Home took the total power consumption with both GPUs working to 305 watts. EVGA recommends a minimum of a 680 watt power supply for systems with this card.
