1. Prepare the Case: If upgrading, remove the old motherboard and any existing I/O shields. Install the new I/O shield for the B550M-ITX/AC.
2. Install the CPU: Carefully align the CPU with the socket, matching the gold triangle on the CPU to the corresponding corner on the socket. Lower the CPU gently and secure it with the retention arm.
3. Install RAM: Open the latches on the DDR4 memory slots. Align the RAM module with the slot, ensuring the notch on the module matches the key in the slot. Press down firmly until the latches click into place.
4. Install M.2 SSD: Locate the M.2 slot. Remove the heatsink and its screw. Insert the M.2 SSD at an angle, then push it down and secure it with the small screw. Reattach the heatsink if applicable.
5. Mount Motherboard: Carefully place the motherboard into the PC case, aligning it with the standoffs. Secure it with screws.
6. Connect Power Supply: Connect the 24-pin ATX power cable and the 8-pin CPU power cable from your power supply to the motherboard.
7. Connect Front Panel Cables: Connect the front panel audio, USB 3.0, USB 2.0, power button, reset button, and LED cables to their respective headers on the motherboard. Refer to the motherboard manual for exact pin layouts.
8. Install CPU Cooler: Install your chosen CPU cooler (air cooler or AIO liquid cooler) according to its specific instructions. Ensure proper thermal paste application.
9. Install Graphics Card: Insert the graphics card into the PCIe 4.0 x16 slot, ensuring it clicks securely. Fasten it to the case with a screw.
10. Cable Management: Organize all cables to ensure proper airflow and a tidy build.
