Gigabyte A620M S2H (AM5/AMD A620/mATX/Q-Flash Plus/Entry-Level AM5) Review
The A620M S2H is Gigabyte's entry-level AM5 board for Ryzen 7000/8000/9000 builds, notable for including Q-Flash Plus BIOS flashback even at this budget price point, a feature that lets buyers update BIOS without a CPU installed.
Gigabyte does not officially disclose an exact phase count or amperage figure for this board's VRM, consistent with most A620-tier boards that omit detailed power delivery specs from public listings. Two DDR5 DIMM slots run in dual-channel mode, standard for entry-level AM5 boards at this price point. A single PCIe 4.0 x16 slot handles the GPU, and this board includes a single PCIe 4.0 M.2 slot for primary storage. A Realtek 1GbE controller handles wired networking without a factory Wi-Fi module. Audio uses a Realtek codec, and PCIe EZ-Latch tool-free installation is included even at this entry price point. Against the Gigabyte A620M Gaming X also in this catalog, the S2H model keeps a simpler feature set while sharing the A620 Gaming X's Q-Flash Plus BIOS flashback convenience.
