ok well umm it won't be exactly 400w but it was just room for powerful hardware possibly in the future, it's more like 300w. How do laptops with gtx 1080's stay so slim then.
First, those aren't 400W laptops. Second, the laptops with straight-up 1080s tend to be extremely bulky. Third, the slim laptops with 1080s are typically using Max-Q versions. Fourth, they're usually using sub-50W CPUs. Fifth, they tend to run hot and have shorter lifespans.
