Comment on Why do (desktop) PC have so few USB ports ?
somethingp@lemmy.world 9 months agoDo you know how motherboards split up this 1amp spec? Does each USB port on a motherboard have 1amp, or do they often end up sharing?

To be compliant with standards, USB ports directly on the motherboard must supply at least 500mA each for USB 2 or 900mA each for USB 3.
They can supply more, but that’s the minimum that should be expected.
