We measure power draw of the graphics card-only, using Nvidia's PCAT tool. A reading under load comes from running Metro Exodus Enhanced Edition for 30 minutes.

Despite both cards sharing a 450W power limit, we did see the X3 OC drawing fractionally more juice. It guzzled down 470W in our test, compared to 461W for the Founders Edition. It's hardly going to make much real-world difference, but it's worth mentioning.

We can see a similar thing when looking at total system power draw. The X3 OC saw the system pull 651 Watts, compared to 644 Watts for the Founders. An 850W PSU is recommended at minimum.
