Gigabyte B550M DS3H AC R2 AM4 Micro-ATX Motherboard Wi-Fi 5
The Gigabyte B550M DS3H AC R2 is a micro-ATX motherboard for AM4 Ryzen processors, designed for builders who need solid core features, Wi-Fi 5 connectivity, and PCIe 4.0 storage support without premium pricing. It handles everything from gaming and content creation to everyday computing with stable power delivery and modern expansion options.
Why this product
AM4 Ryzen 5000 support with PCIe 4.0
Supports Ryzen 5000, 4000 G, and 3000 series processors with PCIe 4.0 x16 graphics bandwidth on the primary slot and PCIe 4.0 x4 on the CPU M.2 socket for fast NVMe drives.
Wi-Fi 5 and Gigabit Ethernet built-in
Dual-band Wi-Fi 802.11ac with Bluetooth 5.0 and Realtek Gigabit LAN provide connectivity without a separate adapter.
Compact micro-ATX form factor
Fits smaller cases while retaining four SATA ports, dual M.2 slots, and three PCIe slots for expandability.
Dual M.2 with mixed PCIe generations
CPU M.2 slot runs PCIe 4.0 (on non-G Ryzen 5000) or PCIe 3.0 (on G-series); chipset M.2 runs PCIe 3.0 x2.
No CPU cooler installation needed for BIOS updates
Q-Flash Plus button lets you update BIOS from USB without removing CPU, memory, or GPU.

Best for
- Builders prioritising compact builds without sacrificing I/O
- First-time overclockers with digital 5+3 phase VRM and BIOS flashback convenience
- Systems requiring wireless connectivity out of the box
- Mixed-storage setups combining NVMe and SATA without bottlenecks
Trade-offs
- Demanding workstations needing more than two M.2 slots or high-speed PCIe expansion
- Builders wanting PCIe 4.0 on both M.2 slots; the chipset slot is limited to PCIe 3.0 x2
- Builds requiring Thunderbolt or USB 3.2 Gen 2 Type-C on the rear I/O
- Users restricted to full-size ATX cases; this is micro-ATX only
The B550M DS3H AC R2 supports AM4 Ryzen 5000 Processors and features unparalleled performance. GIGABYTE B550 motherboards come with upgraded power design, high grade storage standards, and outstanding connectivity that enables you to optimize your performance.
GIGABYTE B550 motherboards maximize your PC's potential with AMD StoreMI technology. StoreMI accelerates traditional storage devices to reduce boot times and enhance the overall user experience. This easy-to-use utility combines the speed of SSDs with the high capacity of HDDs into a single drive, enhances the read/write speeds of the device to match that of SSDs, bolsters data performance for incredible value, and transforms the everyday PC to a performance driven system.
GIGABYTE motherboards use ICs with up to 3 times the ESD resistance levels compared to traditional ICs.
GIGABYTE motherboards feature an audio noise guard that essentially separates the board's sensitive analog audio components from potential noise pollution at the PCB level.
With GIGABYTE Q-Flash Plus, you don't need to install the CPU, memory and graphics card nor enter the BIOS menu to flash the BIOS. Just download and save a new BIOS file (rename to gigabyte.bin) on the USB flash drive, then press the dedicated Q-Flash Plus button and you're good to go!
B550 motherboards feature solid plated ATX 12V 8pin power connectors for offering stable power supply while CPU overloading.
Sulfur compounds in the air can penetrate tiny onboard resistors creating chemical change and causing these resistors to open or short. If either of these occurs the motherboard will fail to function.
