Advanced Power and Thermal Stability
We integrated a 10+1+1 power phase design alongside Dr.MOS technology to ensure smooth current delivery. Because high-density power connectors withstand elevated currents, your system stays protected during demanding tasks. Also, the six-layer PCB lowers temperatures and keeps signal traces clean for memory overclocking.
Next-Generation Storage and Connectivity
You can install ultra-fast solid-state drives using the PCIe Gen5 Blazing M.2 slot. This connection offers double the bandwidth of previous generations for rapid file transfers. Furthermore, the integrated Dragon 2.5 Gb/s LAN delivers uninterrupted networking for large backups and online applications.
Customisable Lighting and Clear Display Outputs
We included both onboard RGB headers and addressable headers so you can easily sync your cooling fans and chassis lighting. For video output without a dedicated graphics card, the rear panel provides both HDMI and DisplayPort options. SignalRGB support also unifies your lighting control across compatible devices.
