Gigabyte B550M DS3H AC AM4 Micro-ATX Motherboard

The Gigabyte B550M DS3H AC is a Micro-ATX motherboard designed for builders who want reliable performance in a smaller case. It supports AMD Ryzen 5000, 4000, and 3000 series processors, giving you plenty of headroom whether you play games, create content, or handle demanding multitasking. Four DDR4 DIMM slots let you install up to 128 GB of memory, so large project files and background apps will not slow you down.

Storage is handled by two M.2 slots that accept fast NVMe SSDs. One slot connects through PCIe 4.0, which means quicker load times for games and heavy software when paired with a compatible processor. A full-length PCIe 4.0 x16 slot is ready for a graphics card built for high performance, and additional PCIe and legacy slots cover expansion cards such as capture or sound cards.

Built-in Wi-Fi 5 and Bluetooth 4.2 keep your setup cable-light and flexible, while Realtek Gigabit LAN provides a stable wired option for competitive online play or large file transfers. If you are using a Ryzen APU with integrated graphics, the rear I/O panel offers HDMI and DVI-D outputs to drive a monitor without adding a discrete GPU.

Smart Fan 5 monitors multiple temperature sensors and controls fan headers automatically, helping the system stay cool without constant manual tweaks. For builders who like a personalized look, RGB Fusion headers allow you to sync lighting strips and other RGB components through Gigabyte’s software.

This board is a natural fit for anyone putting together a gaming rig that needs to slide into a compact tower, a home office PC that doubles as an entertainment center, or a student workstation that maximizes desk space while staying upgrade-friendly.
