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. IThe GIGABYTE GV-N240D5-512I is not a high performance gaming monster, but one area in which it excels is power usage. A high end video card can easily use hundreds of watts of power under full load, and one of the real advantages of cards in this class is that they don't.
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 GIGABYTE GT240 uses a mere 9W of power, while under full load, I measured only a 51 watt usage, which is significantly below NVIDIA's rated 69 watts maximum. This load usage is also substantially below the idle power required by NVIDIA's high end cards. The primary advantage to having a video card like the GeForce GT 240 is that it does not require external power connections from the PSU.
