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.
