How to Install MSI B450M-A PRO MAX

• Prepare your workspace on a flat, static-free surface. Ground yourself before handling components to avoid electrostatic damage, and keep screws and standoffs organized for an efficient build.
• Install the CPU: Open the AM4 socket lever, align the CPU with the socket’s corner marker, and gently seat the processor. Lower the lever to secure the CPU in place. Apply a small amount of thermal paste if your cooler requires it, then mount the CPU cooler and connect its fan to the CPU fan header.
• Install memory: Open the DDR4 DIMM slots and align the memory modules with the notch. Insert firmly into the correct dual-channel slots as indicated by the motherboard user guide (often the A2/B2 slots for two sticks). Ensure both modules click into place with even seating.
• Mount the motherboard: Install the I/O shield into the case, align the motherboard with the case standoffs, and secure it with screws. Check that the board sits flat and does not short on any standoffs.
• Connect power: Attach the 24-pin ATX power connector and the 8-pin (or 4+4-pin) CPU power connector from your power supply. Ensure all power connectors are fully seated and routed cleanly to avoid interference with fans or components.
• Install storage and expansion cards: Insert your NVMe SSD into the M.2 slot and secure with the provided screw. Connect SATA drives to the motherboard ports and route cables for airflow. Install your graphics card into the PCIe x16 slot, securing it with screws and connecting PCIe power if required by the GPU.
• Case connections and peripherals: Connect the front panel USB, audio, and power/reset buttons to the corresponding headers on the motherboard according to the manual. Attach case airflow fans to the motherboard or chassis fan headers to optimize cooling performance.
• First boot and BIOS setup: Power on the system and enter the BIOS/UEFI (usually by pressing Del or F2 during startup). Enable XMP for memory speed if supported by your RAM, set the boot sequence, and check that all components are recognized. Update the BIOS if a newer version is available from MSI’s official site to improve Ryzen compatibility and stability.
• Driver installation and updates: After installing the operating system, install the latest chipset drivers, LAN, audio, and PCIe/NVMe drivers from MSI’s website. This ensures optimal performance, security, and system stability with the most current software.
