how to install Asus Prime B650M-A II-CSM

• Prepare your build space and tools: gather a screwdriver, a stable anti-static surface, and your case, power supply, RAM, CPU, and storage components.
• Install the CPU: Open the AM5 socket lever, align the CPU with the socket, and seat it gently. Engage the latch and ensure the CPU is properly seated before applying thermal paste.
• Apply cooling: Install your processor cooler or CPU heatsink according to the cooler’s instructions, ensuring good contact with the CPU and secure mounting.
• Install memory: Insert the DDR5 DIMMs into the correct two DIMM slots (as recommended by the motherboard manual) with even pressure until they click into place.
• Mount the motherboard: Place the motherboard into the case, align with the I/O shield and standoff posts, then secure with screws. Confirm there are no shorts and the board sits flat.
• Attach power and data cables: Connect the 24-pin ATX power connector and the 8-pin (or 4+4) CPU power connector from the power supply. Route cables cleanly to promote airflow.
• Install storage and expansion cards: M.2 NVMe drives go into the M.2 slots with appropriate screws; install any GPUs or add-in cards into PCIe slots as needed, securing them firmly.
• Connect USB, audio, and fans: Attach USB headers, audio headers, and the chassis fans to the appropriate motherboard headers. Configure fan curves in BIOS for optimal cooling and noise management.
• First boot and BIOS setup: Power on and enter the UEFI BIOS. Enable XMP/EXPO profiles for memory, configure boot order, and check system temperatures. Update the BIOS if a newer version is available for improved stability and features.
• Install operating system: With storage configured, proceed to install your preferred operating system and install motherboard drivers from the ASUS support site or included media for best performance and compatibility.
