The MSI Pro B650-A WiFi is built around the AM5 socket and is compatible with the B650 chipset, housed in a standard ATX form factor measuring 304 mm wide and 243 mm tall. It supports a single CPU and carries no integrated processor or integrated graphics. Wireless connectivity covers Wi-Fi 4 through Wi-Fi 6E alongside Bluetooth 5.3, though aptX audio over Bluetooth is not supported. The board includes dual BIOS for added resilience, although a dedicated clear CMOS button for quick BIOS resets is absent. RGB lighting is present, overclocking is supported, and video output is available via an HDMI 2.1 port. The board is backed by a three-year warranty.
The MSI Pro B650-A WiFi uses DDR5 memory across four slots arranged in a dual-channel configuration, with a standard operating speed of 4800 MHz and overclocked headroom reaching 7600 MHz. Maximum supported capacity sits at 256GB in total, giving ample room for memory-intensive workloads. ECC memory is not supported on this board.
The rear I/O panel offers a varied USB layout, including three USB 3.2 Gen 2 Type-A ports, four USB 3.2 Gen 1 Type-A ports, two USB 2.0 ports, and one USB 3.2 Gen 2x2 port; there are no USB-C ports at Gen 1 or Gen 2 speeds, and no USB 4 or Thunderbolt connectivity. A single Type-C port is present, tied to the Gen 2x2 interface. Display output is handled by one HDMI port and one DisplayPort output, while VGA, DVI, and eSATA are absent entirely. Networking is covered by a single RJ45 port, and there are no PS/2 connectors on this board.
Internal connectivity is well-provisioned, with six SATA 3 connectors and three M.2 sockets available for storage expansion, while SATA 2, mSATA, and U.2 are not present. USB expansion headers include two USB 3.2 Gen 1 connectors, two USB 3.0 connectors, and four USB 2.0 headers for front-panel or accessory use. The board also features eight fan headers, giving considerable flexibility for cooling configurations, along with a dedicated TPM connector for security module integration.
The board provides two PCIe 4.0 x16 slots for full-size expansion cards, along with a single PCIe x1 slot for smaller add-in cards. There are no PCIe 5.0, PCIe 3.0, PCIe 2.0, PCIe x4, PCIe x8, or legacy PCI slots on this board, keeping the expansion layout relatively streamlined.
The onboard audio supports a 7.1-channel configuration with a DAC signal-to-noise ratio of 120 dB, indicating a clean output signal for multi-speaker setups. Five audio connectors are available for analog connections, and an S/PDIF output port is included for digital audio passthrough to compatible receivers or DACs.
The board supports RAID 0, RAID 1, and RAID 10 (1+0) configurations, covering the most common setups for performance striping, mirroring, and a combination of both. RAID 5 and RAID 0+1 are not supported.
