MSI PRO A620M-B (AM5/AMD A620/mATX/DDR5-6800+ OC/Updated CPU Support) Review
The PRO A620M-B is MSI's updated entry-level AM5 board, extending official CPU support through Ryzen 9000-series chips and pushing memory overclock ceilings slightly higher than its A620M-E predecessor.
MSI does not officially disclose an exact phase count or amperage figure for this board's VRM; CPU overclocking remains unsupported on A620 regardless of the specific board revision. Two DDR5 DIMM slots run in dual-channel mode, with MSI's Memory Boost feature enabling overclocked speeds of 6800 MT/s and above, a modest improvement over the A620M-E's rated ceiling. A single PCIe 4.0 x16 slot handles the GPU, and one PCIe 4.0 M.2 slot covers primary storage, matching the A620M-E's storage configuration. Gigabit Ethernet handles wired networking without a factory Wi-Fi module. The exact audio codec model is not disclosed by MSI for this SKU. Against the MSI PRO A620M-E in this catalog, the A620M-B's primary advantages are its updated Ryzen 9000 CPU support list and a slightly higher memory OC ceiling, making it the more future-proof of MSI's two A620 boards.
