MSI B450M-A Pro Max II AM4 Micro-ATX Motherboard

The MSI B450M-A Pro Max II is a Micro-ATX motherboard built on the AMD B450 chipset, designed for the AM4 socket and compatible with AMD Ryzen 5000 Series, 5000 G-Series, 4000 G-Series, 3000 Series, 3000 G-Series, 2000 Series, 2000 G-Series, 1000 Series desktop processors, and Athlon processors with Radeon Vega Graphics. This makes it a versatile foundation for both current-generation and older AMD Ryzen CPU builds without needing an upgrade to a newer platform. The board features MSI's Core Boost technology, which leverages a fully digital power design to support multi-core processors and deliver stable power delivery under sustained workloads. Memory support spans two DDR4 DIMM slots with a maximum capacity of 64GB and speeds ranging from 2667MHz up to 4133MHz via A-XMP overclocking mode, with dual-channel operation supported. Both non-ECC and ECC UDIMM memory types are accommodated, with ECC modules running in non-ECC mode. For storage, a single M.2 slot (M.2_1) connects directly to the CPU and supports PCIe 3.0 x4 and SATA modes for drives in 2242, 2260, and 2280 form factors, enabling fast NVMe SSD installations. Four SATA 6Gbps ports complement this, with RAID 0, RAID 1, and RAID 10 configurations supported across SATA drives. Network connectivity is handled by a Realtek 8125 controller delivering 2.5Gbps LAN, a meaningful step above standard gigabit networking for file transfers and low-latency applications. Audio is powered by a Realtek ALC897 codec offering 7.1-channel High Definition Audio output. Display outputs include one HDMI 1.4 port supporting up to 4K at 24Hz and one DVI-D port supporting up to 1920x1200 at 60Hz, catering to integrated-graphics builds using Ryzen G-Series APUs. Expansion slots comprise one PCIe 3.0 x16 slot from the CPU for discrete graphics and one PCIe 2.0 x1 slot from the chipset. The rear I/O panel provides four USB 3.2 Gen1 Type-A ports (5Gbps) and two USB 2.0 ports, while the board includes internal headers for four additional USB 2.0 and two USB 3.2 Gen1 Type-A front-panel connections. A TPM 2.0 header is present for hardware security module support, and the board carries Windows 11 and Windows 10 64-bit compatibility.
