- Giant cooling blocks with L-shaped heat pipes for optimal thermal design.
Who it fits
Good fit for
This motherboard suits builders who need high performance in a small case. The Mini-ITX size fits tight spaces without sacrificing power. The 10+2+1 phase design handles demanding Ryzen CPUs well. You will appreciate the Wi-Fi 7 and 2.5 GbE ports for fast connections. The smart controls and AI features simplify setup. It is ideal for enthusiasts who want a compact but powerful gaming rig. The robust thermal design ensures stability during heavy loads.
Who should skip it
You should look at another option if you need multiple expansion slots. This Mini-ITX board only offers two M.2 slots. It lacks additional PCIe slots for multiple GPUs or many add-in cards. If you require extensive storage expansion beyond two drives, this board may limit you. The compact size also restricts cable management space. Users needing maximum connectivity options for workstations might find the I/O limited. Consider a larger ATX board if you need more flexibility.
Verdict: The ASUS ROG Strix X870-I delivers strong specs in a small package. It is a solid choice for compact gaming builds.

Setup and Daily Use Guide
Setting up this Mini-ITX board begins with installing an AMD Ryzen processor into the AM5 socket. The listing confirms support for the 9000, 8000, and 7000 series. You will need DDR5 memory modules to populate the slots. The robust 10+2+1 power solution, rated for 110A per stage, handles the electrical load. ProCool II power connections ensure stable delivery to the CPU. For thermal management, the board relies on giant cooling blocks. These blocks feature integrated inlet and outlet protection. They connect via an L-shaped heat pipe and use high conductive thermal fillings to move heat away from critical components. ASUS includes Smart Controls to simplify configuration. Features like AI Overclocking, AI Cooling II, and AI Networking II automate performance tuning. ROG Strix technologies such as Dynamic OC Switcher and Core Flex allow for precise adjustments. Connectivity is handled by Wi-Fi 7 and Bluetooth. A 2.5 GbE Ethernet port provides wired networking. Two M.2 slots offer storage expansion. HDMI 2.0 output supports display connections. Two USB4 ports and USB 3.2 ports provide peripheral options. The Aura RGB system adds lighting customization. This setup suits users who want a compact system with high-end connectivity. The 2.43-pound weight fits standard Mini-ITX cases. You get a streamlined build process with automated software tools. The board is designed for gaming use cases. The three-year warranty from ASUS Turkey adds coverage for your investment.
Before You Buy This Mini-ITX Board
Owning this compact motherboard requires careful planning. You must select a Mini-ITX case that fits the 6.69-inch square footprint. Verify that your chosen case supports the height and provides adequate airflow for the 10+2+1 power stages. The 110A per stage rating handles high-end Ryzen 9000, 8000, and 7000 series CPUs, but you need compatible DDR5 memory. Wi-Fi 7 and Bluetooth offer modern wireless connectivity, so ensure your peripherals support these standards for optimal performance. The 2.5 GbE port may require a compatible router to reach full speeds. This board sits alongside larger ATX options in the 1 product guide. Unlike those, it prioritizes space efficiency over expansion slots. You will need to check your storage needs against the two M.2 slots. Regular maintenance involves keeping the giant cooling blocks free of dust. This setup suits builders who value compact form factors without sacrificing AM5 connectivity.
Check before you buy
- Verify your case supports Mini-ITX form factor dimensions.
- Confirm your CPU is a Ryzen 7000, 8000, or 9000 series.
- Check that you have DDR5 memory modules ready.
- Ensure your router supports Wi-Fi 7 for full speeds.
