ASUS RTX 3080 TUF Gaming OC Review

We measure system-wide power draw from the wall while running the 3DMark Time Spy stress test for 30 minutes.

Total system power draw is inline with the other custom RTX 3080s we have tested, with both BIOS pulling around 475W at the wall.

We also use GPU-Z to measure Board Power (graphics card-only power draw). This is currently only available for Nvidia cards, which is why we have excluded AMD results from the chart. Aside from the fact this is software-based reporting, and not a hardware measurement of the PCIe power cables and PCIe slot (for that we’d need something like PCAT), this should provide us 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.

This is because both of the BIOS options have the same 340W power target, which is the same as the Gigabyte Eagle and MSI RTX 3080 Gaming X Trio models we have tested. Accordingly, board power for all three averages out to 338W.
