Power and Temperature
To test the power and temperature we perform a manual run-through in Cyberpunk 2077 at “Ultra” settings for real-world in-game data. We use GPU-Z sensor data to record the results. We report on the GPU-Z sensor data for “Board Power” and “GPU Chip Power” when available for our Wattage data. For temperature data, we report the GPU (Edge Temp of the GPU) as well as Hot Spot (Junction Temperature) when available for our temperature data.
The ASUS ROG STRIX GeForce RTX 3080 Ti O12G GAMING does consume more board and GPU power draw than a Founders Edition. The higher factory overclock and TDP makes it consume over 400W of board power, which is a lot, just out-of-the-box. That’s about 15% more power to the ASUS ROG STRIX RTX 3080 Ti O12G GAMING with 3x 8-pin PCI-Express Power Connectors required. Overclocking only accelerates that power draw even more, now at 451W board power with the overclock applied on both GPU and memory. That’s another 10% more power for what was only a 5-6% performance increase in games. This is a very power-hungry video card, so make sure you have ample Wattage and no faulty PSU cables.
The ASUS ROG STRIX GeForce RTX 3080 Ti O12G GAMING video card does very well in maintaining thermals at a low sound floor. It kept the GPU and Hot Spot cooler than the Founders Edition by about 4 degrees cooler, and the best part is the fans were not spinning all that fast meaning noise wasn’t an issue. When we overclocked the video card we ran the fans at 100% and even with the highest overclock, and power increase, the temperatures remained the same.
GPU-Z
The first two GPU-Z screenshots are at default, the last two screenshots show the video card overclocked.
