Check AM4 CPU and DDR4 memory

Before ordering confirm your processor is a supported 2nd generation AMD Ryzen AM4 model and that you have DDR4 memory modules. The Micro ATX dimensions require a compatible case with the correct standoff layout. Verify your power supply provides the necessary ATX and CPU power connectors for this board. Ensure any M.2 drive you plan to install matches the keying and length supported by the slot.

Bundled TUF protection and software

Military-grade TUF LANGuard, Chokes, Capacitors and MOSFETs are soldered on to enhance long-term stability under heavy loads. The ASUS TUF Protection suite covers the rear I/O and critical circuits against electrical surges and environmental stress. Included software utilities let you monitor temperatures, adjust fan curves and optimise network traffic for gaming priority. These additions reduce the need for separate protection hardware or third-party tuning tools.
