3080 Ti + 12800H model blade 17 here: so I got ~132W on the GPU and ~42W on the CPU. Pretty sure the limit of the CPU was around 45W so I don't think the CPU power got lowered.
In a rare move, the latest Razer firmware update will boost GPU TGP and thus graphics performance for existing Blade 17 owners. It's essentially more performance out of thin air albeit likely at the cost of slightly warmer core temperatures.
