MSI A520M-A PRO at a glance
The MSI A520M-A PRO uses the Micro-ATX form factor, AM4 socket, and A520M chipset. This is an entry-level platform focused on the essential connections for a practical, lower-cost build.
Memory support is DDR4 across 2 DIMM slots, with up to 64 GB and rated overclocked speeds up to 4600 MT/s. ECC modules are accepted, subject to CPU support. XMP / EXPO memory-profile support is recorded for easier tuning.
Best fit: a budget or straightforward office build using a lower-power CPU and a small number of add-in devices.
Power delivery
The calculated VRM score is 13.0, placing the power delivery in the basic class. The board lists 5 CPU power phases, 50 A power stages in a 5+1 layout. CPU power input is listed as 1. Keep it paired with lower-power processors and avoid sustained overclocked loads.
Expansion and storage
The expansion and storage score is 27.0: focused on the essentials. The platform supports PCIe 3.0. Physical expansion includes 1 ×16 slot, and 1 ×1.
On-board storage consists of 1 M.2 slot supporting PCIe 3.0 and 4 SATA ports. Supported M.2 lengths are listed as 2242, 2260, 2280. The single M.2 slot makes drive planning more important if future expansion matters.
Connectivity and rear I/O
The connectivity score is 29.0, rated essential. There is no recorded onboard Wi-Fi ; wired networking is 1x Realtek® RTL8111H Gigabit LAN controller at up to 1000 Mbps. The recorded USB provision is 6 rear connections; a front-panel total is not recorded. The specification sheet below separates every USB speed and connector type.
Display connectivity includes HDMI 2.1. These motherboard outputs require a processor with integrated graphics.
Audio
The audio score is 45.0. This is a standard onboard solution using Realtek® ALC892/ALC897 Codec. It covers normal gaming and communication; demanding headphones or production work still benefit from an external interface.
Buying verdict
Overall quality is 30.40, a minimal result. Buy it for a simple compatible build, not for expansion, heavy tuning, or a long list of onboard features.
At the recorded Amazon price, the quality-to-price score is 89.0—an excellent value relative to the other boards in the catalog.
