Quick Specs

Performance That Scales with Your Needs

The 14+2+1 power phase design with Dr. MOS technology ensures clean, stable power delivery to your CPU, even under heavy overclocking loads. The 8-layer PCB reduces electrical noise and heat, while Hi-Density Power Connectors provide extra durability for high-current scenarios. This design supports extreme DDR5 memory speeds when paired with XMP/EXPO profiles, giving you headroom for future upgrades.

Storage Versatility for Fast Data Access

With four M.2 slots supporting PCIe 5.0, 4.0, and 3.0, you can install multiple high-speed NVMe SSDs for rapid boot times and file transfers. The board also includes four SATA III ports for additional HDD or SSD storage, and supports RAID 0, 1, and 10 configurations for data protection or performance striping.

Cooling Solutions for Sustained Performance

An aluminum heatsink array covers critical VRM and M.2 areas to dissipate heat effectively during intensive tasks. PWM/DC fan headers auto-detect fan types, and the Fan-Tastic Tuning utility lets you customise curves for quiet operation or maximum cooling. A dedicated water pump header supports all-in-one liquid cooling setups.

Connectivity for Modern Builds

Dragon RTL8125BG 2.5 Gb/s LAN delivers faster, more reliable wired networking than standard gigabit Ethernet. Front-panel USB 3.2 Gen 2×2 Type-C offers up to 20 Gbps transfer speeds, while USB Type-C with DisplayPort Alt Mode enables single-cable monitor connections. No built-in Wi-Fi is included, so plan accordingly.
