Gigabyte B550M DS3H AC R2 mATX Motherboard

5+3 Phases Pure Digital VRM Solution with Low RDS(on) MOSFETs

GIGABYTE UD series motherboards use a 5+3 phases pure digital PWM + Low RDS(on) MOSFETs design to support the 3rd Gen AMD Ryzen™ CPUs by offering incredible precision in delivering power to the motherboard's most power-hungry and energy-sensitive components as well as delivering enhanced system performance and ultimate hardware scalability.

Benefits of Low RDS(on) MOSFETs

• Optimized gate charge to minimize switching losses
• Lower temperature, smaller size, better thermal characteristics

PCIe 4.0* Hardware Design

• PCIe 4.0 Slot: PCIe 4.0 x16 slot with faster bandwidth and lower impedance
• M.2 PCIe 4.0 Slot: M.2 PCIe 4.0 x4 slot with lower impedance

Faster and Better Coverage with Intel Dual Band 802.11ac WIFI + BT 4.2 Module

The onboard 802.11ac WIFI module from Intel® supports Dual Band and up to 433 Mbps, 3x faster WIFI speed than 802.11n and also supports BLUETOOTH 4.2.

Dual NVMe PCIe 4.0*/3.0 M.2 Connectors

With NVMe PCIe 4.0*/3.0 x4 and PCIe 3.0 x2 M.2 connectors onboard, GIGABYTE Motherboards allow users to experience NVMe or SATA mode connectivity for M.2 SSDs. With up to 64 Gb/s transfer speed, this dual M.2 design supports RAID configurations for ideal storage solutions.

Realtek GbE LAN with Bandwidth Management

Realtek Gigabit LAN includes a bandwidth management app that improves latency and maintains low ping times in busy LAN environments.

HDMI 2.1 for 4K / 60P / 21:9 / HDCP 2.3 Support

HDMI 2.1 provides up to 48 Gb/s bandwidth—double that of the previous generation—supporting multiple video streams, 21:9 cinematic ratios, Full HDR, and HDCP 2.3 compatibility.
Note: Only New Gen AMD Ryzen™ with Radeon™ Graphics processors support display output.
