M5 Max MacBook Pro draws over 100W under load, stock Apple charger may not keep up

Users report the MacBook Pro M5 Max regularly pulls over 100W under normal heavy jobs (GPU near 100%, bright screen), meaning Apple's bundled charger and cable may not sustain the battery. An older M1 Pro, by contrast, could run a 15W HDD fine on a 60W charger; an external SSD only draws 1W. Heavy-workload buyers should mind their power setup.
