We measure power consumption from the whole system when idle and when gaming, excluding the monitor.
We measure power consumption under load with the two bioses configured on the card:
329P05HU.Q4C (UEFI, 75C, ASIC power limited to 300W)
329P05HU.Q4D (UEFI, 80C, ASIC power relax to 350W)
System power consumption in a non overclocked state with the Q4C BIOS enabled under load is 330 watts. When we switch to the Q4D BIOS, the system power demand under load increases to 347 watts.
