Overview

An ATX motherboard built on the AMD B650 chipset for Socket AM5 Ryzen 7000 processors. It supports DDR5 memory up to 192 GB and includes PCIe 5.0 connectivity for graphics and storage.

Design and Power Delivery

The board uses a 14+2 virtual phase VRM design rated for 80 A per phase to maintain stable CPU clocks. It measures 305 x 244 mm in standard ATX layout and includes a white PCB aesthetic. Six 4-pin PWM fan headers and dedicated water pump headers provide cooling flexibility.

Memory and Expansion

Four DDR5 slots operate in dual-channel mode with a validated overclock ceiling of 7200 MHz. Expansion includes a full-length PCIe 5.0 x16 slot wired to the CPU and a second x16 slot running at PCIe 3.0 x4. Three M.2 sockets support 2280 drives, with the top slot running at PCIe 5.0 x4.

Connectivity and I/O

Rear I/O features a 20 Gbps USB 3.2 Gen 2x2 Type-C port, a 10 Gbps USB 3.2 Gen 2 Type-A port, four 5 Gbps USB 3.0 ports, and four USB 2.0 ports. Video outputs include HDMI 2.1 and DisplayPort 1.4. Networking uses a Realtek 2.5 GbE controller and a Realtek WiFi 6E plus Bluetooth 5.2 module.

Features and Accessories

BIOS Flashback allows firmware updates without a CPU installed. RGB lighting control is handled by three 5 V ARGB headers and one 12 V RGB header. The box contains a manual, two SATA cables, WiFi antennas, and an M.2 screw set.
