The ASRock B850M Pro Plus Wi-Fi uses an AM5 socket paired with the B850 chipset and comes in a Micro-ATX form factor measuring 244 x 244 mm, making it a compact option within the standard ATX family. It supports overclocking and includes dual BIOS for added firmware reliability, though it does not feature a dedicated clear CMOS button. Wireless connectivity covers Wi-Fi 4, 5, and 6 (802.11n/ac/ax) alongside Bluetooth 5.3, though aptX audio over Bluetooth is not supported. The board carries an HDMI 2.1 output, RGB lighting, and comes with a three-year warranty. It does not include integrated graphics or an integrated CPU, and houses a single CPU socket as expected for a consumer desktop platform.
This board supports DDR5 memory across four slots arranged in a dual-channel configuration, with a maximum supported capacity of 256 GB. Overclocked RAM speeds can reach up to 8000 MHz, providing headroom for high-frequency memory kits. ECC memory is not supported, so the board is oriented toward consumer rather than workstation or server use cases.
The rear I/O panel offers a varied USB selection, including one USB 3.2 Gen 2 Type-A port, two USB 3.2 Gen 1 Type-A ports, one USB 3.2 Gen 2 Type-C port, and four USB 2.0 ports; there are no USB 3.2 Gen 1 Type-C, Gen 2x2, USB 4, Thunderbolt 3, or Thunderbolt 4 ports present. Display output is handled by an HDMI port and one DisplayPort, while legacy video connectors such as VGA and DVI are absent. Networking is covered by a single RJ45 port, and there are no eSATA or PS/2 ports included.
Internal connectivity is well-covered, with three M.2 sockets and four SATA 3 connectors for storage, while SATA 2 and mSATA connectors are not included. USB expansion headers provide four USB 3.2 Gen 1 ports, four USB 3.0 ports, and four USB 2.0 ports through case headers, offering flexible front-panel connectivity. The board includes six fan headers for cooling management and a TPM connector for security module support, though no U.2 sockets are present.
The board provides a single PCIe 5.0 x16 slot as the primary expansion slot, suited for the latest discrete graphics cards and high-bandwidth add-in cards. A secondary PCIe x4 slot is also present for additional expansion needs. No PCIe 4.0, 3.0, 2.0, x16, x8, x1, or legacy PCI slots are included, keeping the layout focused and straightforward for a Micro-ATX form factor.
The onboard audio supports 7.1-channel output and delivers a 120 dB signal-to-noise ratio from the DAC, with three analog audio connectors available on the rear panel. An S/PDIF output port is not included, so digital optical or coaxial audio passthrough is not available through this board.
The board supports RAID 0, RAID 1, and RAID 10 (1+0) configurations, covering common setups for performance striping, mirroring, and a combination of both. RAID 5 and RAID 0+1 are not supported, so those specific array configurations are not available on this platform.
