How to Install Asus Prime B650M-A AX Desktop Motherboard

• Prepare your workspace by grounding yourself and organizing screws, standoffs, and a magnetic screwdriver. Ensure you’re working on a non-static surface to prevent electrostatic discharge.
• Install the CPU into the AM5 socket according to the processor’s alignment marks, then secure the locking lever. Apply a small amount of thermal paste if your cooler requires it, and mount the CPU cooler securely to the motherboard or to the case, following the cooler’s instructions.
• Insert the memory modules into the correct DIMM slots, usually aligning notches with the slot guides. Press down firmly until the modules click into place and the latches snap back to hold them.
• Mount the motherboard into the case using the appropriate standoffs. Connect the power supply cables (24-pin ATX and 8-pin CPU power) to the motherboard, along with any required PCIe power leads for GPUs and other devices.
• Connect the front panel, USB headers, audio, and network leads according to the motherboard’s manual. Attach any case fans and the CPU fan to their respective headers, then review BIOS/UEFI settings for boot order and memory profiles (enable XMP or DOCP if available).
• Power on the system to verify POST, then install your operating system, drivers, and essential software. Return to BIOS to fine-tune boot priority and configure any additional features such as fan curves or performance profiles for your workload.
