LGA 1151 Mini ITX Platform

The ASUS ROG Strix B250I Gaming is a Mini ITX motherboard built for the Intel LGA 1151 socket. It accepts Core i7, i5, i3, Pentium and Celeron processors with Turbo Boost Technology 2.0. The board targets compact systems that still demand ROG-grade audio and networking features.

Dual M.2 and Four SATA Ports

Two M.2 sockets sit alongside four SATA 6Gb/s connectors, giving storage flexibility inside a small chassis. Integrated Intel I219-V Gigabit LAN and IEEE 802.11 a/b/g/n/ac Wi-Fi with Bluetooth remove the need for extra add-in cards. Onboard video output relies on a processor with integrated graphics.

DDR4 2400 Memory Ceiling

Two 288-pin slots support dual-channel DDR4 up to 32 GB total capacity. With 7th Generation Intel CPUs the memory controller runs at 2400 MHz; with 6th Generation CPUs it tops out at 2133 MHz. The SupremeFX S1220A codec delivers 8-channel high-definition audio for sustained gaming or media sessions.
