About MSI PRO B650M‑B Micro‑ATX Motherboard

For small AM5-based PCs, the MSI PRO B650M‑B provides a strong performance base by striking a balance between contemporary features and an affordable design. It supports Ryzen 7000 and 8000 series processors and uses the AMD B650 chipset to serve users looking for setups that are light on content creation or efficient in productivity. With support for up to 128 GB of RAM and 4× DDR5 DIMM slots, memory capabilities allow for overclocking speeds of 7200 MHz, making them ideal for multitasking and improved application performance. A 10 2 1 VRM configuration is used for power delivery, which offers steady and clean output for daily tasks.

A reinforced PCIe 4.0 x16 graphics card slot, a PCIe 3.0 x1 peripheral slot, and three M.2 storage slots—two PCIe 4.0 x4 and one PCIe 5.0 x4—all with thermal shielding are examples of design and expansion features. Four SATA 6 Gb/s ports are also available for legacy storage configuration. With 2.5G LAN, network connectivity is dependable and helpful for quick wired data transfers without the need for separate NICs. USB 3.2 Gen2 Type-C, a variety of USB 3.2 Gen1/Gen2 Type-A ports, HDMI 2.1, DisplayPort 1.4, and USB 2.0 for peripheral use are all included on the rear USB and display panel.

A Realtek codec provides standard 7.1-channel surround sound with PCB isolation for enhanced clarity, delivering audio functionality. With EZ Debug LEDs, a front-panel USB-C header, a Flash BIOS button, and an I/O shield pre-installed, the board accommodates builder convenience. It also adds a single RGB LED header for lighting customisation and expands support for TPM 2.0.
