MSI B450I GAMING PLUS AC AMD motherboard

Socket AM4 Mini-ITX board

The MSI B450I Gaming Plus AC is an AMD B450 motherboard built for Socket AM4 processors. It fits the Mini-ITX form factor and delivers a compact platform for small-form-factor builds. The board provides dual-channel DDR4 memory support and a single PCIe 3.0 x16 expansion slot. It targets users who need a space-saving foundation for Ryzen-based systems.

Builders with compact cases

This board suits builders assembling Mini-ITX rigs that rely on Socket AM4 CPUs and DDR4 modules. It offers four SATA III ports and one M.2 interface for storage, plus 7.1-channel audio and a Gigabit LAN port. It is not for systems requiring more than two DIMM slots or multiple full-length graphics cards. Buyers needing additional PCIe lanes or higher memory capacity should look elsewhere.

Dual-channel DDR4 up to 32 GB

The memory controller supports dual-channel DDR4 at speeds from 1866 to 3466 MHz with a maximum capacity of 32 GB. This single specification determines whether the board matches your planned memory kit. Verify your modules match the supported frequencies and total capacity before purchase.
