Benchmark System And Procedure
We collaborated with HAMEG (Rohde & Schwarz) to upgrade our power consumption measurement system.
We record all channels and the corresponding oscilloscope value/curves for our measurements. The very precise and, more important, fast current clamps yield 100 mV/A, making it easy to calculate the power based on the voltage. We also record the supply voltage to multiply its value with the recorded amperage. Depending on the resolution we choose, this procedure yields a very detailed power consumption history. We generally set this to 1 ms, allowing us to capture all fluctuations attributable to AMD’s PowerTune or Nvidia’s GPU Boost technology.

Power Consumption While Running A Gaming Loop
"How much power does a graphics card draw during gaming?" and "How much heat does it generate under load?" are the most commonly asked questions once we wrap up our analysis of 3D performance. Our testing is made as real-world as possible by measuring cards that have already been warmed up.
This high-resolution measurement shows why power supplies can be overwhelmed unless they have ample output headroom. Even if a PSU's specs suggest it should be able to handle a given card, some very brief (often less than 10 ms), but very high peaks can cause a power supply's protection circuitry to engage.
