How to Install Asus Prime B550M-A AC

• Prepare your workspace and ensure you have a compatible case, power supply, CPU, RAM, storage, and cooling solution. Ground yourself to prevent static damage before handling components.
• Install the CPU into the AM4 socket on the motherboard, aligning notches correctly and securing the lever. Apply an appropriate amount of thermal paste if your cooler requires it, then mount the CPU cooler firmly.
• Insert RAM modules into the DIMM slots, ensuring they click into place on both sides. For best performance, populate slots according to the motherboard manual (often dual-channel configuration).
• Mount the motherboard into your PC case using the standoffs. Align I/O shield with the rear I/O cutout, then secure the board with screws in the standoffs.
• Install M.2 SSDs into the dual M.2 slots and tighten with the small screws provided. Connect SATA drives if you’re adding traditional storage, and route cables neatly for airflow.
• Connect power: attach the 24-pin ATX power connector and the 8-pin (or 4+4) CPU power connector to the motherboard. Connect the 4/8-pin auxiliary power as required by your PSU and motherboard model.
• Attach case fans, front-panel USB, audio, and other front-panel connectors following the motherboard’s labeled headers. If you’re using the onboard WiFi antenna, install it accordingly.
• Power on and enter the BIOS to configure memory XMP profiles, fan curves, boot order, and any RAID or storage configurations. Save changes and install your operating system and drivers from ASUS and component manufacturers.
