Robust power and AI features
The motherboard uses a 14+2+2 power solution rated for 80A per stage with ProCool power connectors. AI Cache Boost enhances the performance of large language models by optimising CPU cache and memory channels, delivering up to 29% higher local LLM performance. ASUS AI Advisor uses AI to understand natural language questions, letting users explore the features and advanced capabilities of ASUS motherboards in a straightforward way. AI Networking II combines technologies that continuously optimise network performance, provide a reliable connection, and unlock the speed of WiFi 7. PBO Enhancement aggressively tunes PBO parameters, leveraging the motherboard's robust power solution for an even greater performance boost. AEMP is a firmware feature for memory modules with PMIC restrictions.
Advanced cooling and connectivity
The board is equipped with a VRM heatsink, M.2 heatsinks, an M.2 backplate, and fan headers for the CPU, pump, and chassis. WiFi 7 with ASUS WiFi Q-Antenna offers a 160MHz-wide 6GHz band and 4096 QAM, which delivers faster WiFi speeds. The board fully utilises the modern standard, offering comprehensive PCIe 5.0 support for faster SSDs and graphics cards. Armoury Crate software centralises control of supported gaming products and includes ASUS Fan Xpert 4 for comprehensive fan control.
Personalisation
The BIOS Q-Dashboard simplifies motherboard configuration with a visual display of hardware connections and corresponding BIOS settings. The M.2 Q-Release, M.2 Q-Slide, and M.2 Q-LATCH innovations make installing storage devices easier. The PCIe Slot Q-Release Slim enables easy removal of graphics cards. The Q-Antenna makes connecting the WiFi antenna simple. The Q-LED diagnostic display helps with troubleshooting potential issues. The Clear CMOS button and BIOS FlashBack button simplify control. ASUS Aura Sync offers preset lighting effects with the ability to synchronise with compatible ROG graphics cards, monitors, keyboards, and mice. TurboV Core software provides intuitive in-Windows overclocking without needing the BIOS interface or restarts.

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