Overview

A flagship AM5 ATX motherboard for AMD Ryzen 9000-7000 processors with DDR5 memory support, Wi-Fi 7, 10Gb and 5Gb LAN, PCIe 5.0 and five M.2 slots including two PCIe 5.0 slots.

This sits at the high end of the AM5 lineup, with a 20+2+2 power stage design and dual USB4 ports aimed at builders who want headroom for demanding workloads and heavy overclocking rather than a standard gaming build. The AI-branded features (AI Cache Boost, AI Overclocking, AI Cooling) are ASUS software tools for tuning the system automatically, not a separate AI chip. DIY touches like the Q-Latch and Q-Release slot mechanisms exist specifically to speed up building without extra tools.

20+2+2 power stage design

Who it's for

Builders assembling a high-end AM5 workstation or gaming PC who want maximum M.2 and networking headroom. Overkill for a budget or mid-range build.

Strengths and trade-offs

Drawn from this product's published specifications.

What stands out

20+2+2 power stage design for sustained overclocking
Five M.2 slots with dedicated cooling, two at PCIe 5.0
Dual USB4 ports plus 10Gb and 5Gb Ethernet
Tool-free Q-Latch and Q-Release design for building

What to check first

High-end pricing tier likely exceeds a mid-range build's needs
ATX size requires a full-size case

Performance notes

The 20(110A)+2(110A)+2 power stage design and ProCool II connectors are built to keep power delivery stable under sustained overclocking and heavy loads. Five M.2 slots (two PCIe 5.0, three PCIe 4.0) each get dedicated cooling, aimed at builders running multiple fast drives rather than a single boot SSD. Dual USB4 ports plus 10Gb and 5Gb Ethernet on top of Wi-Fi 7 give more simultaneous high-bandwidth connectivity than most boards on this socket.
