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 (4K) for this testing.

As expected, we can see a slightly higher power draw when using the OC BIOS, averaging 372W in Cyberpunk 2077. That’s about a 16W increase over stock, though the Silent BIOS is dead level with the reference card, drawing just under 356W power.
