Yes, it is. Are you familiar with any usb spec? The ports in your pc simply cannot even deliver 240W. Also, rying to use pretty much any cable to deliver that kind of power would melt it.

To add to that, there’s a data throughput limit (important for a VR headset, external drives, etc) . There’s also the latency aspect. I would not like to connect my controller dongle, dac, mouse or kb to a hub for example because that adds unnecesary latency. There are several reasons for using a dedicated port for each device and power has nothing to do with it.

Why would you charge things from your PC?

Are you really this dense? Why would I not? It’s not only convenient but it’s also because I don’t have that many outlets available after plugging in 2 studio monitors, 2 displays, a laptop for work and my personal PC.

Really, it’s pretty unvelivable that you’d defend putting in the minimum amount of ports possible considering current chipset capabilities and the sheer size of the required ATX rear panel size. In case you’re unfamiliar, here’s the ATX spec. Not to mention that motherboards are getting more and more expensive and there’s no excuse for increasing cost and reducing functionality.
