Overview

A Micro-ATX motherboard built on the AMD B850 chipset for socket AM5 processors. It supports Ryzen 9000, 8000, and 7000 series CPUs with PCIe 5.0 graphics and storage, DDR5 memory overclocking to 8000 MT/s, and integrated Wi-Fi 7.

Platform and CPU Support

The board uses the AMD B850 chipset and AM5 socket, compatible with Ryzen 9000, 8000, and 7000 series processors. A 4-pin plus 8-pin CPU power configuration delivers stable current for overclocking high-end chips.

Memory and Storage

Four DDR5 DIMM slots accept up to 256 GB with overclocked speeds reaching 8000 MT/s. Storage includes one PCIe 5.0 x4 M.2, two PCIe 4.0 M.2 slots, and four SATA 6 Gbps ports for mixed drive configurations.

Expansion and Rear I/O

A single PCIe 5.0 x16 slot handles modern graphics cards, while a PCIe 4.0 x4 slot adds extra expansion. Rear I/O provides USB 3.1 Type-C, USB 3.1 Type-A, two USB 3.0 Type-A, four USB 2.0 Type-A, HDMI, DisplayPort, 2.5 Gbps LAN, and Wi-Fi 7 antenna connectors.

Cooling and Connectivity Details

VRM and M.2 heatsinks keep thermals in check. Five 4-pin PWM fan headers support custom cooling loops. Internal headers include one USB 3.2 Gen 2 Type-C, two USB 3.0 headers, two USB 2.0 headers, RGB and addressable RGB connectors, front audio, and SPI TPM.
