I have to correct myself. The 140W were the desktop system. With everything included (screen etc) I just checked and had a power draw of 166W at the power outlet. Those aren't TDPs, that is the actual power draw including PSU losses and it is also the max draw, it doesn't really get higher than that. My system is only 4060 like in performance, it is actually a Strix Halo with an integrated 8060s, with a combined CPU+GPU TDP limit of 100W. That has the advantage that I basically have no VRAM limitation (in Indiana Jones: The Great Circle I saw pretty continuous 12 GB memory used by the GPU) at the downside of limited bandwith, still quite close to a 4060 but much lower than high end GPUs of course.

Yes, my system is absolutely not representative. It was one of my goals to get an as energy efficient setup as I could while getting the necessary performance to be able to play modern games.

On modern gaming PCs 500W actual power draw during gaming does sound possible, on my previous system which had a pretty similar performance, but with dGPU (6750 XT). There I had a power draw of roughly 280-300W without the screen, during gaming, if I remember correctly.
