You need a compact board that still gives you four DIMM slots, a dedicated M.2, and built-in Wi-Fi — without the ATX footprint eating up your case space. The B550M DS3H AC is Micro-ATX at 24.4 × 24.4 cm, so it fits smaller towers and desktops where space is tight. AMD B550 chipset, Socket AM4 for Ryzen. Four DDR4 DIMMs up to 128 GB. One PCIe x16 slot for your GPU. M.2 (Socket 3) for a fast NVMe drive, plus SATA III for secondary storage. Intel Wi-Fi AC 3168 and Realtek Gigabit LAN cover both wireless and wired. Four USB 3.2 Gen 1 ports on the back panel, four USB 2.0. RAID 0/1/10 supported. Windows 10 or 11, 64-bit. Straightforward, no-nonsense build for a home office PC, a classroom machine, or a small-business workstation that just needs to boot up and stay up. Add to cart
