Power Consumption and Temperature Testing
My power testing was done using the famous Kill-A-Watt P3. For our idle tests we allowed the computer to sit at the desktop for 15 minutes so that everything could settle in, we then measured our power usage. For our load tests we used Furmark to measure the maximum power draw. We ran the test for 15 minutes and then noted our power usage. Power usage shown is for the entire system, not just the graphics cards that are tested.
For our temperature testing we allowed the XFX 7850 Black Edition to come to an idle for 15 minutes before we measured our load temperatures. For our load temperature testing we loaded up Furmark and ran the default burn-in test for 15 minutes and recorded our results. Our gaming temperature tests were done while we ran our Heaven 3.0 benchmarks.
