Power Draw

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 A Plague Tale: Requiem (4K/2160p) for this testing.

As for power draw, ASUS has not increased the default power target above the 360W TGP figure, and in practice we saw power draw hitting just about 350W, which is right in line with the MSI Suprim SOC.

For those interested, in the video we also test live current readings of the 12VHPWR cable, using a clamp meter. Under full load, each of the six 12V wires ranged from 4.28-5.05A, so load balancing is absolutely fine, and the total across all six wires hit about 28.5A, which checks out considering the power draw we measured. So there was nothing out of spec for this example, but as we know, bad things can and do happen with this connector.

Performance per Watt

Combining the power draw values shown above with the performance data, we present performance per Watt for each graphics card tested:

Just to quickly touch on efficiency, performance per Watt is right in line with the 5080 FE and Suprim models – it can't quite hit the lofty heights as the RX 9070, but the 5080 is the next most efficient GPU we have tested and the Noctua Edition does not change that fact.
