Mini-ITX AMD B550 board

This ASUS ROG STRIX B550-I GAMING motherboard uses the AMD B550 chipset and a Socket AM4 interface in a Mini-ITX form factor. It supports DDR4 memory up to a 64GB maximum capacity. The compact design targets small-form-factor gaming builds or workstations that need strong single-threaded performance.

Verify Socket AM4 cooler clearance

Before ordering, confirm that your chosen CPU cooler fits the Mini-ITX layout around the Socket AM4 socket. Check that your DDR4 modules will not interfere with the cooler or the single PCIe slot. Ensure the power supply provides the required EPS connector for the CPU and that the chassis can mount a Mini-ITX board with its specific I/O shield.

VRM cooling handles sustained loads in a compact

The onboard voltage-regulator cooling is designed to maintain stable delivery during extended gaming or rendering sessions inside a Mini-ITX case. Airflow restriction in small enclosures makes VRM thermal capacity important for consistent boost behaviour over long periods rather than only in short bursts.
