Key Specifications

Enhanced Power Delivery for Stable Overclocking

The 8+2+1 power phase design with Dr. MOS technology delivers clean, consistent power to your CPU. This intelligent power stage solution handles higher currents per phase than traditional MOSFETs, resulting in better thermal performance and improved stability during demanding workloads or overclocking sessions.

Future-Ready Storage Performance

With three M.2 slots including one PCIe 5.0 capable slot, this motherboard supports the latest ultra-fast NVMe SSDs. The Blazing M.2 slot offers up to 128GB/s transfer speeds—twice that of previous generations—making it ideal for content creators and gamers who need rapid data access. Two additional PCIe 4.0 M.2 slots provide flexible storage expansion options.

Intelligent Thermal Management

The optimized aluminum heatsink design effectively dissipates heat from critical components, maintaining system stability during intensive tasks. ASRock’s comprehensive cooling solution includes PWM/DC fan support with automatic detection, plus the Fan-Tastic Tuning feature that automatically calibrates fan curves for optimal noise-to-performance balance.

Robust Connectivity Options

Beyond the 2.5Gb/s LAN for fast, reliable networking, this motherboard offers extensive connectivity including USB 3.2 Gen 2 Type-C, multiple USB 3.2 Gen 1 ports, and dual graphics outputs (HDMI 2.1 + DisplayPort 1.4).
