My GPU utilization, when rendering scenes in Blender, is completely maxed:

However, my power draw is nowhere near maxed:

Default Power Limit : N/A
Enforced Power Limit : N/A
Min Power Limit : N/A
Max Power Limit : N/A
This is when plugged in to the stock 300W charger, power draw drops to 20W when unplugged. Windows claims that the maximum graphics power is 130W, which is corroborated by online sources. However, the same Blender Render in classroom also draws between 35-37W, far below the rated power draw for my GPU.
I have an NVIDIA RTX 3060 Mobile paired with a Ryzen 5800H in my Lenovo Legion 5. I am running PopOS 22.04 LTS, using the latest NVIDIA driver (525), and the latest kernel (6.07-76). The power draw is the same, regardless of whether I use switchable or discrete graphics. This is with the High Performance battery setting, the Performance Lenovo power setting, and "Prefer Maximum Performance" in the X Server settings.
