A friend of mine has an Asus with some Nvidia GPU (3070? not sure), a 5th gen ryzen 9 and a 200+W power brick.
That thing is twice as thick as my 2013 MBP and the case is plastic. It also has more vents than my mbp, each of which has more surface area than all those on the mbp combined. I also suspect the fans are bigger.
He actually bought it to play games on it and never complained about performance dropping after a while. So I suppose it manages to move the 200 W of heat somehow.
