There are gaming laptops that come with power bricks rated for higher output than a Mac Studio's power supply. M3 Ultra levels of power dissipation are possible to handle in a laptop, but it wouldn't look much like a MacBook Pro. That kind of gaming laptop typically has four fans (compared to two on a MacBook Pro), and large vents on the sides, bottom, and back of the machine allowing them to move a lot more air through the system.
