Socket AM4 DDR4 Platform

The MSI A320M Gaming Pro is a Micro ATX motherboard built around the AMD A320 chipset for Socket AM4 processors. It accepts AMD RYZEN series CPUs as well as 7th generation A-series and Athlon chips. Dual-channel DDR4 memory runs at 1866, 2133, 2400, 2667, 2933 (OC) or 3200 (OC) MHz up to 32GB total capacity.

Build Integration

A single PCIe 3.0 x16 slot provides x16 bandwidth with RYZEN CPUs and x8 with 7th generation A-series or Athlon CPUs. Two PCIe 2.0 x1 slots add further expansion room. Storage connects through one M.2 interface and four SATA III ports. Rear I/O supplies two USB 3.1 Gen1 ports and two USB 2.0 ports while internal headers add four more USB 2.0 connections. A Realtek 8111H Gigabit LAN port handles wired networking.

Included Extras

The package ships with the motherboard, a CMOS battery, one SATA cable and a chassis I/O back panel. No WiFi antenna is included because the board lacks a built-in WiFi module. Realtek ALC887 audio delivers 7.1 channel output for surround sound. These bundled items cover the essentials for a basic system assembly.
