Stable power and cooling
A 12+2+1 phase power design with Dr.MOS technology and upgraded 20K capacitors, which offer a 1000µF capacity for a more stable output current and longer life, ensures reliable system operation. The board uses 2oz copper inner PCB layers, which contributes to more effective heat dissipation and better energy efficiency, especially when overclocking. Support for DDR5 memory with frequencies up to 8000+ MHz (OC) and AMD EXPO or Intel XMP profiles maximises system throughput for demanding applications, while an optimised circuit design ensures stability.
Expansion slots and storage
For graphics cards, there is a main PCIe 5.0 x16 slot with a reinforced design and an easy-release mechanism, which makes handling easier in a confined case space. The storage space can be configured using three M.2 slots, with the primary Blazing M.2 slot using a PCIe 5.0 x4 interface with transfer speeds of up to 128Gb/s for fast SSDs. Two other slots operate on the PCIe 4.0 standard, complemented by four SATA III connectors for classic hard drives, with support for RAID arrays to increase speed or data security.
Connectivity and audio
Network connectivity is provided by a modern Wi-Fi 7 (802.11be) module with Multi-Link Operation support for low latency, and a Dragon 2.5Gb LAN wired interface with intelligent bandwidth management. The audio output is handled by a 7.1-channel Realtek ALC1220 codec with Nahimic Audio technology, which provides clear, surround sound with detailed settings for various use scenarios.

Choosing a motherboard
When choosing a motherboard, it is important to pay particular attention to the motherboard's socket type, format and chipset. These are among the most important parameters and ensure 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 will determine which other components you need to select for your future computer.Specifications
