Power and Temperature
Power

There isn’t much you can say that the chart doesn’t. The MSI GeForce RTX 5090 32G SUPRIM SOC needs a substantial amount of power. Given that the 12V 6×2 power cable is rated at 600 Watts, you need everything you have under the hood for this graphics card. The TBP for this video card, selecting the “Gaming mode” on the BIOS switch, is indeed 600 Watts, so we took all of that and a pinch more. Looking at the MSI GeForce RTX 4090 SUPRIM X 24G, the difference is 210 Watts or 53%.



We thought it would be interesting to look at our old friend, the Kill-A-Watt meter, comparing the raw power draw at the wall. We measured the baseline idle for our Test System and then measured power draw using the Cyberpunk 2077 benchmark at native 4K. The difference after subtracting the idle draw is 208 Watts or 44%. So whether you use digital measurements or the trusty old-school Kill-A-Watt, 200 Watts is 200 Watts.
Temperature


These two charts show exactly what MSI is aiming for in the SUPRIM video card. The feature points on the webpage discuss in some detail the work that goes into the heatsink and fans. Whether it is an RTX 4090 or an RTX 5090, the results speak for themselves. Keep in mind that these results are on an open test bench, and the mileage may be different inside a PC case. Also, recall that both video cards were tested with the fans set to “Auto”. In the case of the MSI GeForce RTX 5090 32G SUPRIM SOC never goes above 44%. We could not hear any fan noise.
