Robust Power and Cooling

The VRM uses an 8+2 DrMOS power stage design. This configuration supports high-core-count AMD Ryzen processors efficiently. Stack Cool 3+ uses 2-ounce copper layers to draw heat away from critical components. This design helps maintain optimal temperatures during sustained loads.

ProCool sockets ensure flush contact with PSU lines. This reduces impedance and helps prevent hotspots. Military-grade TUF chokes and capacitors deliver stable power, improving overall system reliability.

Comprehensive Connectivity

This board includes Wi-Fi 6 and 2.5 Gigabit Ethernet for low-latency networking. The rear I/O offers USB 3.2 Gen 2 Type-C and multiple Type-A ports. HDMI 2.1 supports 4K displays at 60 Hz.

You also get BIOS FlashBack for easy updates without a CPU or memory installed. Armoury Crate software centralises control of lighting and system settings.

Enhanced DIY and Protection

TUF components and SafeSlot technology provide physical durability. The PCIe slot is reinforced for better retention and shearing resistance. ESD guards protect components from static discharge, exceeding industry standards.

TUF LANGuard improves signal throughput and protects against electrical surges. The stainless-steel back I/O panel offers corrosion resistance for longer lifespan in varied environments.

Immersive Gaming Audio

DTS® Custom audio provides positional cues for gaming. Three presets—Aerial, Soundscape, and Tactical—optimise sound for different genres. This helps detect enemy movements in FPS titles or immerse you in RPG worlds.

Two-Way AI Noise Cancelation removes background noise from voice communication. It supports 3.5 mm, USB, and Bluetooth headsets with minimal CPU impact.
