Description

The Gigabyte B550M AORUS ELITE (rev. 1.3) is an AMD B550 Ultra Durable motherboard with several notable features. It uses a 5+3 phases pure digital PWM design with Low RDS (on) MOSFETs for precise power delivery to energy-sensitive components. The motherboard supports high-speed graphics cards through its PCIe 4.0 x16 slot and offers dual M.2 connectors for ultra-fast NVMe SSD storage. Other features include Realtek GbE LAN, Smart Fan 5 with FAN STOP, and RGB FUSION 2.0 for addressable LED and RGB LED control.
