The GIGABYTE B550 motherboard uses 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. With NVMe PCIe 4.0 x4 and PCIe 3.0 x2 M.2 connectors onboard, GIGABYTE motherboards bring users to experience NVMe mode or SATA mode connectivity for M.2 SSD devices. Delivering up to 64Gb/s data transfer speed, the dual M.2 connectors provide an ideal storage solution while also supporting in RAID modes. Realtek 8118 LAN is a high-performance and friendly network chip for players with automatic bandwidth allocation to ensure the highest network priority of the game or application. It can provide users with comprehensive features and fast and smooth Internet experience. 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. With the B550 motherboard, RGB Fusion 2.0 is even better with addressable LEDs. Already feature-filled with colors and patterns, RGB Fusion 2.0 is now upgraded to improve the addressable LED support. With external addressable LED strips where each LED is digitally addressable, users can experience even more patterns, styles, and illuminations. GIGABYTE motherboards use high-end audio capacitors. These high-quality capacitors help deliver high-resolution and high-fidelity audio to provide the most realistic sound effects for gamers.
