MSI B450 Tomahawk Max DDR4 AMD Motherboard

The MSI B450 Tomahawk Max is an ATX-form-factor motherboard built on the AMD B450 chipset, designed for Socket AM4 and compatible with 1st, 2nd, and 3rd Generation AMD Ryzen processors, as well as Ryzen with Radeon Vega Graphics, 2nd Gen Ryzen with Radeon Graphics, and Athlon with Radeon Vega Graphics desktop processors. Its military-inspired aesthetic is backed by a fully digital power design and extended PWM heatsink, enabling stable power delivery even under sustained multi-core workloads. For memory, the board provides four DDR4 DIMM slots supporting dual-channel operation with a maximum capacity of 64 GB. JEDEC speeds range from 1866 MHz to 2667 MHz, while AMD Ryzen 3rd Gen CPUs (R5/R7/R9) can reach up to 4133 MHz via A-XMP overclocking mode. Non-ECC UDIMM and ECC UDIMM (operating in non-ECC mode) are both supported. Storage options include a single M.2 Key-M slot capable of PCIe 3.0 x4 (or x2 on Athlon CPUs) and SATA 6 Gb/s, supporting 2242, 2260, 2280, and 22110 form-factor drives. Six SATA 6 Gb/s ports are available in total across chipset and CPU lanes, with RAID 0, 1, and 10 support on the B450 chipset SATA ports. Note that SATA5 and SATA6 become unavailable when an M.2 device is installed. Connectivity is handled by a Realtek 8111H Gigabit LAN controller. USB ports include two USB 3.2 Gen2 ports (one Type-A, one Type-C) on the rear panel for 10 Gbps transfers, two USB 3.2 Gen1 Type-A rear ports from the CPU, and six USB 2.0 ports in total. Audio is powered by a Realtek ALC892 codec delivering 7.1-channel High Definition Audio. Two 5050 RGB LED strip headers (12 V) allow basic lighting customisation. Expansion slots consist of one PCIe 3.0 x16 slot for discrete graphics, one PCIe 2.0 x16 physical slot wired at x4 for multi-GPU or add-in cards, and three PCIe 2.0 x1 slots. Two-way AMD CrossFire is supported. The rear panel also features a dedicated Flash BIOS Button, allowing firmware updates via USB without installing a CPU, memory, or graphics card.
