Adding High-Power USB ports to PC for running Samsung Dex

concorde77 · October 24, 2020

Hey guys,

I decided to set up Samsung Dex so I could still use my phone while I'm on my PC. But even through the 3.0 ports, my phone tends to charge very slowly while it's plugged in. On a lot of the newer prebuilt PCs, I've noticed that they started coming with "high-powered USBs" (with the little lightning bolt) or "Fast charging ports" built in. Like this:

I've been doing a lot of research online for an upgrade. But all I've been able to find are external charging peripherals; most of which don't carry data at all.

Does anyone know if it's possible to install extra internal USB ports on my PC with both high-power charging and data transfer? And if so, what kind of power requirements should I be looking at so I won't overload my PSU?

You might already be good with a regular powered USB hub, and only have the phone connected to that so it gets all the 'juice'.

How about a USB C PD add-in card.

This specific example can supply up to 93w of power, but you can probably find something that's not so overkill. 20w should be more than enough.

Just search for USB PD PCI-e add-in card or something similar.

Ok, I think I'll give that one a shot. Thanks for all the help!
