AM4 Mini-ITX for compact Ryzen builds
The ASUS ROG STRIX B550-I GAMING is an AMD B550 motherboard in the Mini-ITX form factor. It fits AM4 socket Ryzen processors and provides a full feature set in a small footprint. The board targets builders who want high-end audio and networking in a space-saving chassis.
Suits small-form-factor gamers.
This board suits enthusiasts building a compact gaming system with a Ryzen 5000 series CPU after a BIOS update. It is not suited for users who require four memory slots, extensive internal drive bays or multiple full-length expansion cards. The two-slot memory limit caps total capacity at 64GB.
Dual M.2 slots set the storage ceiling
Two M.2 sockets are provided alongside four SATA 6Gb/s ports with RAID 0/1/10 support. This layout defines how many fast drives can be installed directly on the board. Builders planning more than two M.2 devices must add a controller card or choose a different platform.

Questions sur cet article
Will the VRM or chipset throttle first during a long, heavy workload?
The board uses a robust VRM heatsink and active chipset cooling, so the VRM typically reaches its thermal limit before the B550 chipset under sustained loads.
How loud does the chipset fan get and what power does the board draw at full load?
The tiny chipset fan spins up under load and is audible in a quiet room; total board power draw depends on the installed CPU and memory configuration.
Which CPU, cooler and memory kit must I already have to use this Mini-ITX board?
You need an AM4 Ryzen processor, a low-profile cooler that clears the VRM heatsink, and a DDR4 kit up to 64 GB across the two slots.
