To measure power draw, we hook-up our power meter on another system via USB. Our power meter is capable providing a chart of power the watts currently being consumed by the unit plug into it. We take the average of 15 minutes idle and 15 minutes load to show our power daw. Our load test is SuperPI 12K. A power virus scenario which you will never encounter on regular use. This is a worst-case scenario but is lighter on power than our previous AIDA64 stress test which is an AVX test, which draws more power than normal. The raw data from app is gathered and we get our results. Temperatures are also captures during this time.
Various configurations will play a factor on how much you are consuming and the same applies to our test. We try to keep our test bench uniform at all times (same memory, graphics card, board if possible, etc). All tests are done with the motherboard or CPU on out-of-box settings as indicated in our Test Setup page with only XMP applied.
When tested on motherboards, this shows how motherboard companies tune their BIOS to affect performance which in turn affects power draw and temperatures.
