Well, I know this is an old topic but I’ll comment anyway.
HP Omen with AMD Ryzen 7 5800H and RTX 3060 which should be able to reach 100W.
NVIDIA 545.29.06 driver. EndeavourOS KDE with Kernel 6.7.4-arch1-1.
It’s stuck at 80W on this distro. On Pop_OS! 22.04 NVIDIA LTS with the same driver, I could reach 95W.
