Stable power and memory
The power stage, with its 8+2+1 phase configuration and Dr.MOS technology, provides the processor with a stable and smooth power supply, which is key to maintaining high performance even under heavy loads. The board features a six-layer PCB that optimises signal paths and thermal properties. Support for Intel XMP and AMD EXPO profiles makes it easy to set the optimal parameters for memory modules to achieve maximum system throughput.
Fast interface and storage
For graphics cards, there is a reinforced steel PCIe 5.0 ×16 slot that can handle heavier models and ensures maximum throughput for future hardware. Storage can be installed in one Blazing M.2 slot with a PCIe Gen5 ×4 interface for extremely fast SSDs with transfer speeds of up to 128Gb/s. Two additional Hyper M.2 slots use the PCIe Gen4 ×4 interface, providing ample capacity for the system and data. Four SATA III connectors are available for traditional drives.
Connectivity and networking
Network communication is handled by a 2.5Gb LAN Dragon controller optimised for low latency in online gaming and content streaming. Wireless connectivity is provided by a Wi-Fi 6E module with 6GHz band support and Bluetooth 5.2, which eliminates interference in crowded environments. The connector line-up includes rear USB 3.2 Gen 2 ports, including a modern USB-C interface, and HDMI 2.1 and DisplayPort 1.4 graphics outputs for connecting high-resolution monitors up to 4K at 120Hz.

Choosing a motherboard
When choosing a motherboard (also known as a mainboard), it's important to pay particular attention to the motherboard's socket type, form factor, and chipset. These are among the most crucial parameters, ensuring the board's compatibility with the processor, expansion cards, and other components. The specific socket determines the choice of a suitable processor, while the remaining connectors dictate the selection of other components for your future computer.Specifications
