Overview

An ATX motherboard built on the AMD B850 chipset for AM5 processors. It supports DDR5 memory up to 8000 MT/s and includes Wi-Fi 6E and Bluetooth 5.2.

Design and Power Delivery

The board uses a black and white ATX layout with robust VRM heatsinks. Dual 8-pin CPU power connectors supply stable current for overclocking high-end Ryzen processors. M.2 heatsinks keep NVMe drives cool under load.

Memory and Expansion

Four DIMM slots accept DDR5 up to 256 GB with AMD EXPO and Intel XMP profiles. The primary PCIe 5.0 x16 slot handles next-gen graphics cards, while a second x16 slot runs at PCIe 4.0 x4 for add-in cards.

Storage and Connectivity

Four M.2 sockets provide one PCIe 5.0, two PCIe 4.0, and one PCIe 3.0 x4 interface, plus four SATA 6 Gbps ports. Rear I/O includes USB4 Type-C, USB 3.1 Type-C, four USB 3.0 Type-A, six USB 2.0, HDMI, and DisplayPort over USB-C.

Networking and Extras

A Realtek Dragon RTL8125BG controller drives the 2.5 GbE LAN port. Wi-Fi 6E and Bluetooth 5.2 handle wireless duties. Seven 4-pin PWM headers, RGB and digital RGB headers, BIOS Flashback, and a Realtek ALC897 audio codec round out the feature set.
