Why aren’t motherboards mostly USB-C by now?::I’m beginning to think that the Windows PC that I built in 2015 is ready for retirement (though if Joe Biden can be president at 78, maybe this PC can last until 2029?). In looking at new des…

I dont remember off the top of my head the exact number of conductors, but it has like 22 or 24 very very fine wires in it, that have to be lined up perfectly on both sides of the (comparatively small) connector to be soldered to equally small pads.

So its much more labor and time intensive to make a USB-C connector, compared to a USB Type A, which has big bulky cables and equally bulky (comparatively speaking) pads.

USB Micro/Mini used tiny wires too, but again.. only about 2-4. So far less time and labor to line them up, and even compared to USBC it can still have larger solder pads to connect to due to the number of conductors vs the 22-24 conductors inside the Type-C connector.

And thats just the connectors and the wires. the support circuitry to actually run it is more complex and expensive as well. Which further increases the cost.

And theres just no reason for it, the number of devices that need and benefit from higher speeds USB-C can support are few and far between, and typical motherboards coming with 1-2 type-C sockets is more than enough to support that for 99.99% of the people, and if you are in some very weird niche case scenario where you need a bunch of USB-C ports, you can get a USB-C PCI-Card (just make sure you get a reputable brand one, and not one of the suspiciously cheap no-brand chinese knockoff ones)
