Compact AM5 platform for high-refresh gaming

This motherboard and CPU bundle pairs the ROG STRIX X870-I GAMING WIFI with an 8-core Ryzen 7 9700X processor. The board uses the AMD X870 chipset on a Mini-ITX PCB, supporting Ryzen 7000, 8000 and 9000 series CPUs. Four DDR5 slots accept up to 96 GB of memory, making the kit suited to compact builds that still demand multi-threaded throughput.

AI tuning and overclocking tools simplify setup

ASUS AI Overclocking, AI Cooling II, AI Networking and AEMP profiles automate voltage, fan curves and memory timings. ROG-exclusive Dynamic OC Switcher, Core Flex, Asynchronous Clock and PBO Enhancement give manual control over per-core behaviour. The 10+2+1 power stage design rated at 110 A per stage feeds the CPU through ProCool II connectors, alloy chokes and durable capacitors.

Dense I/O and dual M.2 cooling aid daily assembly

A massive heatsink with integrated I/O cover and high-conductivity pads sits atop an L-shaped backplate. One PCIe 5.0 M.2 slot and one PCIe 4.0 M.2 slot both include substantial cooling. Rear panel provides 2.5 Gbps LAN, Wi-Fi 7 on 2.4, 5 and 6 GHz bands with 320 MHz bandwidth, USB4 and a USB 10 Gbps Type-C connector. Two SATA 6 Gbps ports and a PCIe 5.0 x16 slot complete the layout.

Questions about this item

Will the 10+2+1 power stage rated for 110A per stage need extra cooling under sustained load?

The massive heatsinks with integrated I/O cover, high-conductivity thermal pads and L-shaped backplate are designed to handle the 110A per stage power delivery for multi-core processors.

What limits the PCIe 5.0 M.2 slot to PCIe 4.0 speeds when a Ryzen 8000 series CPU is installed?

The M.2_1 slot runs at PCIe 5.0 x4 with Ryzen 9000 and 7000 series processors, but drops to PCIe 4.0 x4 with Ryzen 8000 series processors.

How loud do the chassis and AIO pump headers run when the system operates all day?

AI Cooling II automatically adjusts fan speeds on the 4-pin CPU fan, AIO pump and chassis fan headers based on real-time temperatures to balance airflow and noise.
