USB connectivity includes four USB 3.2 Gen 1 ports and six USB 2.0 ports across rear panel and internal headers.

Cooling and RGB Control

Smart Fan 5 technology provides intelligent cooling management with multiple temperature sensors and hybrid fan headers supporting both PWM and voltage mode. The FAN STOP feature can halt fans completely under low temperatures for silent operation. RGB Fusion 2.0 supports both standard RGB and addressable LED strips with up to 300 individually controllable LEDs.

Audio and Build Quality

High-end audio capacitors and an audio noise guard deliver clear sound quality with support for up to 7.1-channel configurations. The anti-sulfur resistor design enhances long-term reliability. Q-Flash Plus allows BIOS updates without installing CPU, memory, or graphics card, simplifying the build process.

Exclusive Realtek 8118 Gaming LAN

High Speed Gigabit LAN with Automatic Bandwidth Allocation
Realtek 8118 LAN is a high performance and friendly network chip for gaming players with automatic bandwidth allocation to ensure the highest network priority of the game or application. It can provide users the most comprehensive features and the fastest and smoothest Internet experience.
Program On Top Gets Highest Priority

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.

Smart Fan 5

With Smart Fan 5 users can ensure that their gaming PC can maintain its performance while staying cool. Smart Fan 5 allows users to interchange their fan headers to reflect different thermal sensors at different locations on the motherboard. Not only that, with Smart Fan 5 more hybrid fan headers that support both PWM and Voltage mode fans have been introduced to make the motherboard more liquid cooling friendly.

RGB FUSION 2.0

With B550 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 B550 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.
