Power phase design
The power system uses a 9+2+1 phase configuration with integrated Dr.MOS circuits for efficient power distribution. These components supply a stable current to the processor, even during intensive gaming or work. The high-density power connectors reliably withstand higher currents and reduce the risk of overheating during demanding overclocking. Two 8-pin 12V connectors help maintain low operating temperatures for the power system.
Advanced PCB design
The board uses an eight-layer PCB to significantly improve signal path stability. This design contributes to lower operating temperatures and high energy efficiency for data transfer. Support for AMD EXPO and Intel XMP profiles makes overclocking DDR5 RAM easy. This lets you increase the frequency of your memory modules for smoother system performance.
Fast storage
For lightning-fast data transfer, the board features a Blazing M.2 slot with a PCIe Gen5 x4 interface, which operates at a theoretical speed of up to 128Gb/s. The second Hyper M.2 slot supports the PCIe Gen4x4 standard with a speed of 64Gb/s for connecting additional fast NVMe SSDs. SSD installation is tool-free thanks to a quick-release latch. This mechanical solution significantly simplifies assembly and overall maintenance of your computer's storage.
Wi-Fi 7 and network interface
Wireless network connectivity is handled by an integrated Wi-Fi 7 module with support for 2.4GHz, 5GHz and 6GHz bands. Multi-Link Operation technology helps reduce latency by using multiple frequency bands simultaneously. Integrated Bluetooth 5.4 makes it easy to connect wireless peripherals and eliminates unnecessary cables on your desk. Wired network connection is provided by the Dragon 2.5Gb/s LAN controller, which offers up to 2.5× more bandwidth than standard Gigabit Ethernet. The network chip optimises data flow for smooth online gaming and high-resolution video streaming. A pre-installed rear port cover speeds up computer assembly and protects the connectors from mechanical damage.
Diagnostics and easy management
The board includes practical features to simplify installation and system diagnostics. The integrated Post Status Checker system indicates the status of key components such as the CPU, memory and graphics card using coloured LEDs during start-up. The BIOS Flashback button is used for easy firmware updates from a USB drive without needing a CPU or RAM installed.
