We use Nvidia PCAT to measure power draw of the graphics card only, with readings from both the PCIe slot and the PCIe power cables combined into a single figure. We use Cyberpunk 2077 (1440p) for this testing.
Power draw for the Aero OC came in a touch below the MSI Ventus 3X, as it hit 274.8W in Cyberpunk 2077 at 4K.
Combining the power draw values shown above with the performance data, we present performance per Watt for each graphics card tested:
That slight drop in power versus the Ventus 3X does improve efficiency by a fraction, but there's not much in it at all.
