Overview

An ATX motherboard built on the AMD B850 chipset for Socket AM5 processors. It supports Ryzen 9000, 8000, and 7000 series CPUs with DDR5 memory up to 8000 MT/s.

Design and Power Delivery

The board uses a black and white ATX layout with VRM and M.2 heatsinks for thermal management. CPU power connects through one 8-pin and one 4-pin connector to support high-end processors during sustained loads.

Memory and Expansion

Four DDR5 DIMM slots accept up to 256 GB with AMD EXPO profiles up to 8000 MT/s. Expansion includes a PCIe 5.0 x16 slot, a PCIe 4.0 x16 slot running at x4, and two PCIe 3.0 x1 slots.

Storage and Connectivity

Three M.2 sockets provide one PCIe 5.0 x4 and two PCIe 4.0 x4 interfaces alongside four SATA 6G ports. Rear I/O offers USB 3.1 Type-C, three USB 3.1 Type-A, two USB 3.0 Type-A, two USB 2.0 Type-A, HDMI, DisplayPort, and 2.5 Gbps LAN.

Wireless and Extras

Integrated Wi-Fi 6E and Bluetooth 5.3 handle wireless networking. Internal headers include a USB4 Type-C, USB 3.1 Type-C, three USB 2.0 headers, three addressable RGB headers, front panel audio, and SPI TPM. BIOS Flashback and Clear CMOS buttons simplify firmware updates and recovery.
