Product Note
This motherboard requires an AMD AM5 processor and DDR5 memory. It is not compatible with Intel CPUs or DDR4 memory. Confirm the exact processor model and BIOS requirements against ASUS’s CPU support list before purchasing.
PCIe and M.2 speeds depend on the installed CPU. The primary M.2 socket supports PCIe 5.0 x4 with compatible Ryzen 7000 and 9000 Series processors but operates at PCIe 4.0 x4 with Ryzen 8000 Series processors. The motherboard has only two SATA ports, so check storage requirements before selecting a case and drive configuration.
Wi-Fi 6E operation on the 6GHz band depends on regional regulations and supported operating systems. The HDMI and DisplayPort outputs require a processor with integrated graphics. The Mini-ITX form factor also requires a compatible case and careful planning for GPU length, cooler clearance, and airflow.
