Hello. The motherboard has a USB 3.1 Gen2 Type-C connector. The Asrock website (https://www.asrock.com/MB/AMD/B450M%20Pro4/index.ru.asp) indicates support for this connector - 3.0A, but when you connect the phone to this connector, the current does not rise above 380mA . What could be the problem? The wire that I connect the phone to this Type-C connector on the motherboard supports 5A.
Configuration: ASRock B450M Pro4 BIOS Version P5.30 CPU type AMD Ryzen 5 3600, 4200 MHz (42 x 100) |

Usually it is not the USB port but the cable that you use.
When you buy a USB C to C cable, on some shops, you see that one cable claims 5Gb/s, and other claim 10Gb/s. Also keep in mind that USB ports are always working in pairs of 2, which is called a Hub, on B450M pro 4 you see that the USB C is paired with another Light Blue USB A port, they both ar connected to the same pioint on the board, and both must share resources. I tested, conencting my pgone via the 5GB cable, and it took almost 5 hours to charge, did the same test later with the 10Gb cable and guess what, around 2 hours. Try with a USB a to C cable (10 Gb/s) and see if this is betetr, if it is on the same hub. If yes (which is often the case), it is definitely the USB cable, not the board |
