I think power delivery is a concern too. If a motherboard had 4 USB-C ports on it, you know someone would try to plug in 4 USB-C monitors at 100W (20V/5A) each, so 400W going across your IO bus. At that point if your motherboard doesn’t just burn out, and you have a big enough power supply to provide it, you’re still going to have a serious heat problem.
Yeah I recently started using a motherboard that has a 6-pin GPU style header for powering the USB-C ports. It limits power delivery capacity if you don’t plug the connector in, but if you do it supports 100W ports.
100W on each port or 100W total output for all 6 ports? I seriously doubt your power supply will deliver 600W on one peripheral cable.
No it limits the total amount, but it is reasonable that they added a dedicated power input. I’m guessing we’ll see even more of that on ATX12VO motherboards or similar. Seems like power standards are changing a lot and manufacturers are waiting for things to settle down.
Don’t support 100W power delivery on all ports then.
I think it’s easy to say this, but harder to actually do in practice. There’s a color code system for USB-A, but a lot of manufacturers didn’t follow it reliably, and most users don’t know what the differences are anyway (I’d certainly have to look up what Yellow and Red are specifically for). You’d have the same problem with trying to mark USB-C ports, and without some easily identifiable marking most users will just expect that a USB-C port is a USB-C port.
