MSI PRO A520M-S AM4 mATX Motherboard

The MSI PRO A520M-S motherboard (AMD A520, AM4, mATX, DDR4) is a compact desktop board built around the AMD A520 chipset and AM4 socket. It supports AMD Ryzen 5000, 5000 G-Series, 4000 G-Series, 3000, and 3000 G-Series processors. Two DIMM slots accept up to 64 GB of unbuffered, non-ECC DDR4 in dual-channel mode, with supported memory speeds reaching 4600 MHz for higher-frequency DDR4 kits. The A520 platform provides a practical foundation for everyday home and office PCs.

Rear connectivity consists of four USB 3.2 Gen 1 Type-A ports and two USB 2.0 Type-A ports. A single HDMI 1.4 output serves as the board's rear display connection. The 1 Gbps RJ-45 port handles wired networking; Wi-Fi and Bluetooth are not built in. Power is supplied through standard 24-pin ATX and 8-pin CPU connections. Cooling headers comprise one CPU fan connector and one chassis fan connector, which is relevant when planning case airflow.
