Optimized VRM Design for Stable Overclocking

Engineered with a 14+1+1 power phase design and Dr. MOS technology, the motherboard delivers smooth, high-current power delivery to the CPU. The upgraded 20K Black capacitors (1000µF) improve capacitance, reduce ripple, and maintain stable output under heavy loads. Combined with 2oz copper PCB and Hi-Density Power Connectors, this ensures lower temperatures and enhanced durability during overclocking sessions.

High-Speed Storage and Memory Performance

This board supports the latest DDR5 memory with XMP/EXPO profiles for easy overclocking, offering up to 256 GB across four DIMM slots. Four M.2 slots include one PCIe 5.0 capable “Blazing M.2” for ultra-fast SSDs (up to 128 Gb/s) and three PCIe 4.0 slots for additional high-speed storage. SATA III ports and RAID support provide flexible storage configurations for gamers and creators.

Advanced Cooling and DIY-Friendly Features

A comprehensive cooling solution includes an enlarged aluminum heatsink, PWM/DC fan support, and a thermistor header for custom thermal management. The Fan-Tastic Tuning feature auto-detects fan minimum duty for quieter operation. Toolless M.2 heatsink designs, anti-drop screws, and an enlarged graphics card latch simplify installation and upgrades.

Next-Gen Connectivity and Audio

Equipped with Wi-Fi 6E (802.11ax) and Bluetooth 5.3, the motherboard ensures fast, low-latency wireless connections. The Dragon RTL8125BG 2.5Gb LAN delivers stable wired performance. Audio is powered by Realtek ALC1220 with Nahimic software, offering immersive 7.1 surround sound, noise cancellation, and voice stabilization for clear communication.
