Graphics—NVIDIA GeForce RTX 5090 Laptop GPU, 24 GB GDDR7; ROG Boost 1647 MHz; 120 W (100 W + 20 W Dynamic Boost)

120 W is the upper power limit including Dynamic Boost: the extra 20 W is shifted to the GPU when the processor load is low and is not always available. The RTX 5070 Ti version of the same chassis is limited to 115 W, and the RTX 5060 and 5070 versions to 105 W.

ASUS
Graphics switching—MUX Switch and NVIDIA Advanced Optimus

Advanced Optimus switches the internal display between the processor’s integrated graphics and the RTX 5090 without a restart. The MUX switch connects the display directly to the RTX 5090, removing the integrated graphics from the path in games.
