The Ryzen 7 5800X is a 5th generation processor and requires a motherboard that supports this generation. However, the TUF B450-Plus Gaming only supports up to the 3rd generation of Ryzen processors. Therefore, it is not directly compatible with the Ryzen 7 5800X. However, it may be possible to extend compatibility through a BIOS update if the board has been updated accordingly by ASUS. You should check the official ASUS website for the latest BIOS updates and compatibility information.
