Comment on Why aren’t motherboards mostly USB-C by now?
NaibofTabr@infosec.pub 1 year agoI 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.

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.
