Microsoft Surface Book 2 is the most powerful Surface Book ever made. The Surface Book 2 15-inch comes with a gaming class discrete GPU 6GB GTX 1060 that is really great for gaming. However, there is a problem that Surface Book 2 can’t be compared to a dedicated gaming laptop is the power supply. The 95W power supply that comes with Surface Book 2 15-inch can’t supply enough juice when the Surface Book set to high performance to play some heavy game.
I think this problem has also happened to my Surface Pro 3 when I turned the brightness all the way up and running heavy programs. I think Surface Book made for performance and portability, so it can’t have a too big power supply with it.
