Will any of these pci-e cards allow for "fast charging" using usb-c cable?

[Car712]

Hey so I have an ASUS tuf x570 (wifi) motherboard and I tried using the usb-c to usb-c cable that came with my new note 20 ultra to fast charge it, and it will show fast charging for a few seconds than suddenly switch to slow charging, obviously this is an issue with port not providing enough power, so I have decided to get a pci-e card to fix this, all of these seem to have a internal connector for SATA power, which I would assume would mean that these infact can fast charge, but im not entirely sure, I have found these on amazon and want to make sure:

 

(I would *really* rather have one that fits in the pci-e x1 slot, as the board only has 2 full slots and I may want to use something else in the 2nd full slot at a later time)

A problem that you're going to have isn't necessarily that the port can't deliver enough power but that the negotiation between the phone and the port won't allow it. There's some computer logic behind weather a device slow or quick changes. It's not strictly that it can't deliver enough amps.

 

I would look for something that advertise quick charging or product reviews that say it has it as a feature. If it doesn't say it had it it's a gamble not in your favor that it will.

Gonna say, unlikely. They have SATA power connectors on them, but that's probably only to supply 5V. The Note 20's fast charge requires USB 3.1 PD with PPS (PD 2.0). If it doesn't supply PD, then it's 15w max. Most laptops will not provide 15w, only 7.5w on USB-C. Desktop motherboards are equally unlikely to provide the needed 100w to the USB-C port to enable PD.

Don't know about samsung, but my phone won't even fast charge with another adapter that has PD of equal or higher ratings, only the manufacturer's one. There's some proprietary protocol in play.

Unless it advertises that it works specifically for your phone, don't bet on it. Even then it might not. Usb charging is supposed to be universal, but that's only true on the standard setting.

Thanks for all the reply's, guess ill just buy a samsung fast charging brick for my desk area heh..

If you want something to put in your PC, you could just get a charger for cars, the kind you put in cigarette lighter. Those take 12v DC, which you conveniently have on molex and sata connectors.

 

You could get something like this: https://www.amazon.com/Anker-Charger-PowerIQ-PowerDrive-Delivery/dp/B07RL2N8YY/

 

and a molex to sata or molex / sata to pci-e 6/8 pin  adapter cable, cut the adapter cable in half and attach the connector you want to the charger's 12v and ground wires.
