Robust Power for Ryzen Performance

The motherboard features an 8+2+1 power phase design with Dr. MOS. This provides smooth and stable power to the CPU. It supports demanding workloads and enhances performance for gamers. The Hi-Density power connectors withstand higher currents. This design ensures system stability, even during heavy overclocking sessions.

Blazing Fast Storage and Memory

You get three M.2 slots for high-speed storage. The primary slot supports PCIe Gen5 for future-proof speeds. Two additional Gen4 slots cater to existing ultra-fast SSDs. The board also supports DDR5 memory with XMP and EXPO profiles. This allows for easy memory overclocking to boost your system’s responsiveness.

Advanced Cooling and Connectivity

Intelligent cooling design includes an aluminium heatsink for efficient heat dissipation. PWM/DC fan support and Fan-Tastic Tuning allow for quiet, customised cooling curves. For connectivity, Wi-Fi 6E offers lower latency on the 6GHz band. The Dragon 2.5Gb/s LAN provides up to 2.5X the bandwidth of standard gigabit Ethernet.

DIY-Friendly Features and RGB

This board includes dual graphics outputs (HDMI + DisplayPort) for flexibility. Reinforced steel slots securely support heavy PCIe 5.0 graphics cards. Building is easier with the Auto Driver Installer and BIOS Flashback, which updates the BIOS without a CPU or RAM. Polychrome RGB headers let you synchronise lighting with compatible components.
