Power and Temp
On this page, we will look at the power and temperature, that the Overclocked NVIDIA GeForce RTX 5080 Founders Edition runs at. We will utilize both GPU-Z and HWiNFO64 to collect data and look at the sensor information they both provide. We collected the data running Cyberpunk 2077 at 4K and “Ultra” settings on all video cards.
Power
The TDP of the NVIDIA GeForce RTX 5080 Founders Edition is 360W. When the NVIDIA GeForce RTX 5080 Founders Edition is at default, we got very near that 360W TDP board power, we hit 357.8W at default. When we overclocked the NVIDIA GeForce RTX 5080 Founders Edition, the power increased to 389.6W, an increase of 9% to the board power. This falls in line, just about, with the performance increase we got as well. At this new power level, it is the second most power-hungry card here and falls 10% under the GeForce RTX 4090 FE on power. When the GeForce RTX 5080 FE is overclocked, it consumes 28% more power than the GeForce RTX 4080 SUPER FE.
Temperature
For the temperature reading, we were running 80% locked fan speed on the Overclocked GeForce RTX 5080 Founders Edition to make sure it was operating at as high of an overclock as we could push. Therefore, its temperature decreased over the card non-overclocked and was at 67.7c. Otherwise, when the GeForce RTX 5080 FE is not overclocked, at default fan speeds, it was the warmest running GPU, but definitely not hot, and not largely different from the other GPUs here. Overall, we did not need to enable this 80% fan speed, it would hold the overclock just fine at default fan speeds.
