How to Install MSI A520M-A PRO

Before you start, prepare a clean workspace with static-safe conditions and have a suitable screwdriver. Read the motherboard manual to locate the mounting holes, standoffs, and connector names. This guide provides a high-level overview to help you assemble a reliable system without missing key steps.

1) Prepare your case and I/O shield: Remove the side panel and install the I/O shield into the back of the chassis. Ensure it snaps into place securely to avoid loose connectors during panel operations.

2) Install the motherboard standoffs: Choose the correct standoff positions that align with the Micro ATX form factor and the motherboard’s screw holes. Secure the standoffs to the case so the board sits flat and grounded when mounted.

3) Install the CPU and memory: Open the CPU socket lever, align the processor correctly with the pin-1 corner, and seat it into place. Close the socket latch. Install RAM modules in the appropriate DIMM slots, aligning notches and firmly seating them until the latches click.

4) Mount the motherboard and connect power: Place the motherboard into the case, align the I/O shield with the ports, and secure it with screws. Connect the 24-pin main power cable and the 8-pin (or 4+4) CPU power cable from the power supply. Attach any additional power connectors required by your build.

5) Install storage, graphics, and peripherals: Install storage drives (SATA or M.2 where supported) and, if using a discrete graphics card, seat it firmly in the PCIe slot and secure it with screws. Connect required data and power cables for drives, and connect your case’s front-panel USB, audio, and power/reset cables to the corresponding headers on the motherboard according to the manual.

6) Final checks and BIOS setup: Double-check all cables for secure connections, reseat any components if you notice looseness, and power on to enter the BIOS. Update firmware if needed, enable profiles for memory and storage, and configure boot order. Save settings and exit to begin installing your operating system and applications.

Following these steps helps ensure a solid foundation for your system, with the MSI A520M-A PRO providing a dependable platform for everyday productivity and professional tasks. The board’s design emphasizes reliable power delivery, straightforward expansion, and a compact footprint that fits a wide range of cases while maintaining easy access to essential connectors and features.
