ASUS TUF Gaming b650 doesn't support fast charging?

I built a new pc a few days back, but can't seem to get fast charging to work on it.
I noticed it has specific USB 10 blue ports that are for faster than other USB ports, so why does only slow charging work when I plug in a fast charging 3A USB C?
I have checked about drivers, armory crate doesn't offer me to install any missing drivers.
Any ideas what I could do?
