    DisplayPort has a +3.3V 500mA pin specifically for pushing power. In theory, great for powering an active adapter. In practice, has killed motherboards because Dell can’t design a computer for shit.

      Friendly reminder that if you use a Dell charger on a HP, nothing happens but vice versa, you damage the motherboard. It kills a chip used for charging. Dell used the same size barrel jack, but they wired it differently from everyone.
