MSI RTX 3090 Gaming X Trio 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 comes in over 500W for the RTX 3090 Gaming X Trio, making this the most power hungry GPU I have ever tested.

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 MSI has pushed the power target to 370W, or 20W above the reference spec for the RTX 3090.
