The MSI AX1800 Network Adapter (GUAX18) is compatible with any computer or laptop with a USB port, including the ASUS ROG STRIX B550-A GAMING motherboard, as long as it has a USB port. Since the adapter uses a USB-A port and is compatible with USB 2.0, USB 3.2 Gen 1 and other ports, it will work without a problem with the motherboard mentioned.

Thank you very much
