Overview
The Gigabyte B850M C is a Micro ATX motherboard built on the AMD B850 chipset with an AM5 socket. It supports AMD Ryzen 9000, 8000 and 7000 Series processors and includes X3D Turbo Mode, a BIOS feature for one-click gaming performance tuning.
Power comes from a digital 6+2+2 phase VRM design with digital PWM and DrMOS, and a UD power connector with a UD Solid Pin 8-pin CPU connector. A VRM heatsink handles cooling, and Smart Fan 6 offers four PWM/DC fan headers with a dual fan curve mode. Memory support is dual channel DDR5 across 4 DIMM slots with AMD EXPO support, and DDR5 overclocking goes up to 8200 MT/s.
Storage and expansion include three M.2 slots (one PCIe 5.0 and two PCIe 4.0, one of them on the back of the board), four SATA 6Gb/s connectors, a PCIe 5.0 x16 slot and three PCIe 3.0 x1 slots. Networking is 2.5GbE LAN plus Wi-Fi 7, with DisplayPort and HDMI outputs, and Hi-Fi audio with high-end audio capacitors and an Audio Noise Guard.
DIY-friendly features include PCIe EZ-Latch, the EZ-Debug Zone with debug LEDs, WIFI EZ-Plug, Q-Flash Plus for updating the BIOS without a CPU, RAM or GPU, and a UC BIOS with multi-theme and AIO fan control.
