• Optimizing computer responsiveness from system boot to application launch
• Offering SSD performance with HDD capacity at an affordable cost
• Quickly accessing key files by automatically learning users’ computing behaviors

10+3 Phases Pure Digital VRM Solution with Low RDS(on) MOSFETs

GIGABYTE B550 UD AC series motherboards use a 10+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.

M.2 PCIe 4.0 Slot

M.2 PCIe 4.0 x4 slot with Lower impedance.

PCIe 4.0 Slot

PCIe 4.0 x16 slot with faster bandwidth and lower impedance.

Dual Band 802.11ac Wi-Fi

The GIGABYTE B550 UD AC onboard 802.11ac Wi-Fi module from Intel® supports Dual Band and up to 1.73Gbps, 5x faster Wi-Fi speed than 802.11n and also support BLUETOOTH 5.

Realtek GbE LAN with Bandwidth Management

Realtek Gigabit LAN features a network bandwidth management application which helps to improve network latency and maintain low ping times to deliver better responsiveness in crowded LAN environments.

Dual NVMe PCIe 4.0*/3.0 M.2 Connectors

With NVMe PCIe 4.0*/3.0 x4 and PCIe 3.0 x4 M.2 connectors onboard, GIGABYTE B550 UD AC Motherboards bring users to experience NVMe mode or SATA mode connectivity for M.2 SSD devices. Delivering up to 64 Gb/s data transfer speed, the dual M.2 connectors design provides an ideal storage solution while also supporting in RAID modes.

USB Type-C™ Front Panel Connector

Equipped with next generation connectivity, GIGABYTE Motherboards already support the chassis of the future. The onboard USB Type-C™ header for USB 3.2 Gen1 makes access convenient when connecting a USB 3.2 Gen1 device or charging your mobile device.

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

HDMI 2.1, which is backwards compatible with HDMI 2.0/ 1.4 and offering 48 Gb/s of bandwidth – twice times more than previous generation. This unlocks the potential for users to transfer multiple video streams, as well as a native cinematic 21:9 ratio (which most movies are shot in), Full HDR and HDCP 2.3 support, to offer the best visual experience for viewers.

RGB FUSION 2.0

• With GIGABYTE B550 UD AC Motherboards, RGB Fusion 2.0 is even better with Addressable LEDs. RGB Fusion 2.0 offers users the option to control onboard RGB and external RGB / Addressable LED light strips* for their PC build. Already feature filled with colors and patterns, RGB Fusion 2.0 are now upgraded to improve the Addressable LED support. With external Addressable LED strips, where each LED is digitally addressable that users can experience even more patterns, styles, and illuminations.
• With GIGABYTE B550 UD AC Motherboards support the external 5V Addressable LED lighting strips and up to 300 LED lights. RGB Fusion 2.0 with Addressable LEDs comes with new patterns and various speed settings with more to come.

Hybrid Fan Pin Headers

Assume complete control over your liquid cooling setup! Smart Fan 5 receives up-to-the-second information on flow-rate and water-temperature through the Hybrid Fan Pin Headers or external thermistor sensors—giving you absolute mastery over your PC.
• All Hybrid Fan Headers can automatically detect the type of cooling device whether it be fan or pump with different PWM or Voltage mode.
