Socket AM4 Mini-ITX Board

This MSI B450I Gaming Plus Max Wifi motherboard fits the Mini-ITX form factor and uses the AMD B450 chipset. It is built for compact systems that run AMD Ryzen or Athlon processors with Radeon Vega graphics. The board supports dual-channel DDR4 memory up to 64GB capacity. Integrated Wi-Fi and a Realtek 8111H Gigabit LAN controller handle networking.

CPU Generation and Memory Speed

Verify which Ryzen or Athlon generation you plan to install because the primary PCIe 3.0 x16 slot runs at x16 speed with 1st, 2nd and 3rd Gen Ryzen, at x8 speed with Ryzen and Radeon Vega Graphics processors, and at x4 speed with Athlon and Radeon Vega graphics processors. Confirm your DDR4 modules match one of the listed frequencies from 1866 through 3466 MHz. Ensure your case and power supply provide the required connectors for a Mini-ITX layout.

Included Back Panel and Antenna

The package supplies a chassis I/O back panel, one SATA cable and a CMOS battery. A Wi-Fi antenna is included because the board has a built-in Wi-Fi module. No additional cables, brackets or driver discs are provided. The Realtek ALC887 codec delivers 7.1 channel audio through the rear ports.

Questions about this item

What accessories come in the box and what must I buy separately?

The box contains the motherboard, a CMOS battery, one SATA cable, the rear I/O back panel and the Wi-Fi antenna. You will need to purchase the CPU, DDR4 memory, storage drives, power supply, case and CPU cooler separately.

Which memory speed should I choose for this board?

The board supports dual-channel DDR4 from 1866 up to 3466 MHz. Pick a kit that matches the speed your Ryzen processor officially supports; the board will run it at the highest common frequency.

What does the single PCIe 3.0 x16 slot mean for my graphics card?

With a Ryzen 1st, 2nd or 3rd Gen CPU the slot runs at x16 speed, with a Ryzen or Athlon APU it drops to x8 or x4 respectively, so your graphics card bandwidth depends on which processor you install.
