The ROG STRIX B650E-I GAMING WIFI motherboard supports Ryzen 7000 and 8000 Series processors, but does not directly specify support for the Ryzen 7 9800X3D. However, the Ryzen 7 9800X3D is part of the 7000 Series, so it may be compatible. To confirm compatibility, I recommend checking the list of supported processors on the manufacturer's official website.
