Overview
The MSI B450M-A Pro Max is a Micro-ATX motherboard built on the AMD B450 chipset, designed for the AM4 socket. It is compatible with 1st, 2nd, and 3rd Generation AMD Ryzen processors, Ryzen with Radeon Vega Graphics, 2nd Gen AMD Ryzen with Radeon Graphics, as well as Athlon with Radeon Vega Graphics, A-series, and Athlon X4 desktop processors. Memory support is provided through two DDR4 DIMM slots accommodating up to 64 GB of RAM in a dual-channel configuration. JEDEC-rated speeds include 1866, 2133, 2400, and 2667 MHz, while A-XMP overclocking profiles allow Ryzen Gen 3 (R5/R7/R9) systems to reach up to 4133 MHz. Both ECC UDIMM (operating in non-ECC mode) and non-ECC UDIMM modules are supported. For storage, the board offers four SATA 6 Gb/s ports with support for RAID 0, RAID 1, and RAID 10 configurations, plus a single M.2 Key-M slot that runs at PCIe 3.0 x4 or SATA 6 Gb/s speeds with Ryzen-based processors and supports 2242, 2280, and 22110 form-factor drives. Expansion is handled by one PCIe 3.0 x16 slot and one PCIe 2.0 x1 slot. Onboard display outputs include one DVI-D port (up to 1920×1200 @ 60 Hz) and one HDMI 1.4 port (up to 4096×2160 @ 24 Hz), both active only when using a processor with integrated graphics. Audio is managed by a Realtek ALC892 codec delivering 7.1-channel High Definition Audio, while networking is handled by a Realtek 8111H Gigabit LAN controller. USB connectivity consists of six USB 3.2 Gen 1 ports (four on the rear panel, two via internal header) and six USB 2.0 ports (two on the rear panel, four via internal headers). The rear I/O panel also includes PS/2 keyboard and mouse ports alongside the video, LAN, and audio outputs.
