Socket AM4 platform

The MSI B450M-A PRO MAX is a Micro-ATX motherboard built around the AMD B450 chipset for Socket AM4 processors. It supports 1st, 2nd and 3rd Gen Ryzen desktop CPUs as well as Athlon and A-series APUs with Radeon graphics. The board targets budget-conscious builders assembling compact office or home systems.

32 GB dual-channel DDR4 headroom

Four DIMM slots accept up to 32 GB of dual-channel DDR4 memory with supported speeds ranging from 2667 to 4133 MHz on Ryzen 3000 series processors. The 32 GB ceiling suits mainstream multitasking and gaming, while heavier content-creation workloads will hit the capacity limit.

PCIe 3.0 and SATA III connectivity

A single PCIe 3.0 x16 slot provides graphics bandwidth at x16, x8 or x4 depending on the installed CPU generation. Storage connects through one M.2 interface and four SATA III ports. Rear I/O includes four USB 3.2 Gen1 ports, two USB 2.0 ports and a Realtek 8111H Gigabit LAN controller, while 7.1-channel audio is handled by the Realtek ALC892/897 codec.

Questions about this item

Will my existing DDR4-3200 memory run at its rated speed on the B450M-A PRO MAX?

The board supports DDR4 up to 4133 MHz with Ryzen 3000 series CPUs, so 3200 MHz modules will operate at their rated frequency when paired with a compatible processor.

How can I confirm the Realtek ALC892 audio is functioning after assembly?

Connect speakers or headphones to the rear panel jacks, play audio in Windows Sound settings and verify 7.1-channel output appears in the Realtek Audio Console.

Does the box contain an M.2 mounting screw or Wi-Fi antenna?

The package includes the motherboard, a CMOS battery, one SATA cable and the rear I/O shield; no M.2 screw or Wi-Fi antenna is supplied.
