MSI A520M-A PRO Motherboard

The MSI A520M-A PRO is a Micro-ATX motherboard built on the AMD A520 chipset with an AM4 socket, designed to support AMD Ryzen 5000 Series, 5000 G-Series, 4000 G-Series, 3000 Series, and 3000 G-Series processors. It is an accessible platform for home office builds, productivity workstations, and entry-level desktop PCs that benefit from AMD's AM4 ecosystem. The board accommodates two DDR4 memory slots with a combined maximum capacity of 64 GB in a dual-channel configuration. JEDEC speeds range from 1866 MHz through 3200 MHz, while A-XMP overclocking profiles push supported kits up to 4600 MHz (1 DIMM per channel, single-rank). MSI's DDR4 Boost technology uses dedicated PCB routing to help maintain signal integrity across those speeds. Storage flexibility comes from four SATA 6 Gb/s ports and one M.2 Key-M slot that runs at PCIe 3.0 x4 or SATA 6 Gb/s when used with Ryzen 5000, 5000 G, 4000 G, 3000, or 3000 G processors, accommodating 2242, 2260, and 2280 form-factor drives. SATA RAID 0, 1, and 10 are supported, as are RAID 0 and RAID 1 for NVMe storage. Connectivity includes a Realtek RTL8111H Gigabit LAN controller, six USB 2.0 ports (two rear, four internal header), and six USB 3.2 Gen 1 5 Gbps ports (four rear Type-A from the processor, two via internal header). Audio is handled by a Realtek ALC892/ALC897 codec delivering 7.1-channel high-definition audio. Display output options on the rear panel include one HDMI 2.1 port (up to 4096×2160 at 60 Hz with HDCP 1.4 and 2.3) and one DVI-D port (up to 1920×1200 at 60 Hz), both requiring a processor with integrated graphics. The single PCIe 3.0 x16 slot accepts discrete graphics cards and runs at full x16 speed with Ryzen 5000, 5000 G, 4000 G, and 3000 processors. MSI's Core Boost technology uses a digital power design to provide stable VRM delivery for multi-core Ryzen processors. The 2 oz thickened copper PCB is intended to aid thermal performance across the power delivery and trace layers.
