Stable power supply
The power system, with its 8+1+1 phase configuration, delivers stable voltage directly to the installed processor. Integrated Dr.MOS power stages efficiently regulate voltage and reduce the operating temperature of the entire system. The board uses durable, high-density power connectors that easily withstand higher currents under heavy loads. Power is supplied via one 24-pin ATX connector, one 8-pin 12V connector, and one 4-pin 12V connector.
Fast DDR5 RAM
Four DIMM slots can hold up to 256GB of system memory in a dual-channel configuration. The motherboard fully supports AMD EXPO and Intel XMP overclocking profiles, which simplify setting higher frequencies. Users can easily set high frequencies up to 8000MHz. The system works with both DDR5 ECC and non-ECC unbuffered modules.
Modern interface
The main PCI Express 5.0 x16 slot, reinforced with steel, provides a firm grip for heavy graphics cards. The board also includes one PCIe 4.0 x16 slot and one PCIe 4.0 x1 slot for additional expansion cards. Reinforced solder points maintain signal stability even during demanding operation. The metal slot protects the board from mechanical damage when installing heavy components.
Fast data storage and network connectivity
For data storage, there are two M.2 slots, the first of which uses a PCIe Gen5 x4 interface with transfer speeds of up to 128Gb/s. The second Hyper M.2 slot operates on a PCIe Gen4x4 interface with speeds of 64Gb/s. An aluminium heatsink efficiently dissipates heat from fast SSDs under load. For connecting traditional drives, there are four SATA III ports with support for RAID 0, 1, and 10 disk arrays. The integrated 2.5Gb/s Dragon network card significantly speeds up file transfers and data backups. The network controller automatically optimises bandwidth for online gaming or smooth video streaming. Special gaming ports reduce latency and jitter for the connected mouse and keyboard. The board also includes an M.2 Key E expansion slot for the additional installation of a wireless Wi-Fi module.
Easy installation and management
The EZ Setting system simplifies the assembly and subsequent maintenance of the entire computer. The BIOS Flashback button on the rear panel lets you update the firmware with just a power supply and a USB drive connected. The Post Status Checker light indicator signals the status of the processor, memory, and graphics card during start-up. Installation is made easier by the pre-mounted rear I/O shield and a tool-less SSD mounting system.

Choosing a motherboard
When choosing a motherboard, it’s important to pay particular attention to the socket type, form factor and chipset. These parameters are among the most crucial and ensure the board’s compatibility with the processor, expansion cards and other components. The specific socket determines your choice of processor, while the remaining connectors dictate which other components you’ll need for your future computer.Specifications
