We measure system-wide power draw from the wall while running Cyberpunk 2077 for 30 minutes.

Of the four RTX 3090 Tis we have now tested, the Amp Extreme Holo has the lowest power target of them all, so understandably its total system power is the lowest. It's still very high, mind you, coming in just shy of 670W, so you will still need a very decent PSU.

We also 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. This provides us with significantly more accurate data to work with as it is measuring only the GPU power, and not total system power which is a fundamentally imprecise measurement.

Despite the 450W power target, we actually saw the Amp Extreme Holo exceed that value, drawing just under 467W in Cyberpunk 2077. It's still the most frugal RTX 3090 Ti we've tested, but not by a lot.
