The ASRock X870 Pro-A Wi-Fi uses the AM5 socket paired with the X870 chipset and follows the standard ATX form factor, measuring 305 mm wide and 244 mm tall. It supports a broad range of wireless standards through its built-in Wi-Fi module, covering Wi-Fi 4 through Wi-Fi 7 (802.11be), and includes Bluetooth 5.4, though aptX audio codec support is not available. The board features an HDMI 2.1 output for display connectivity, RGB lighting, and a dual BIOS configuration for added firmware reliability, while BIOS reset via a dedicated clear CMOS button is not supported. Overclocking is accessible through the BIOS, and the board carries a 3-year warranty. It does not include an integrated CPU or onboard graphics, and accommodates a single processor.
The board supports DDR5 memory across four slots arranged in a dual-channel configuration, with a maximum supported capacity of 256GB. Overclocked RAM speeds can reach up to 8000 MHz, offering headroom for high-frequency memory kits. ECC memory is not supported.
The rear I/O panel includes two USB 4 40Gbps ports and two Thunderbolt 4 ports, all in USB-C form factor, alongside two USB 3.2 Gen 2 USB-A ports, one USB 3.2 Gen 1 USB-A port, and four USB 2.0 ports. No USB 3.2 Gen 2x2, USB 4 20Gbps, or Thunderbolt 3 ports are present. For display output, there is one HDMI port, while DisplayPort, DVI, and VGA connectors are absent. Network connectivity is handled by a single RJ45 port, and legacy PS/2 and eSATA ports are not included.
Internal connectivity includes three M.2 sockets and four SATA 3 connectors for storage, while SATA 2 and U.2 sockets are absent, and mSATA is not supported. For USB expansion via headers, the board provides four USB 3.2 Gen 1 ports, four additional USB 3.0 ports, and four USB 2.0 ports. Cooling is managed through six fan headers, and a TPM connector is present for security module support.
The board offers a total of four full-length PCIe slots, consisting of one PCIe 5.0 x16 slot and three PCIe 4.0 x16 slots. Older PCIe generations — including PCIe 3.0, 2.0, and legacy PCI — are not represented, and there are no PCIe x1, x4, or x8 slots present.
The onboard audio supports a 7.1-channel configuration and is accessible through three analog audio connectors. An S/PDIF output port is not included.
The board supports RAID 0, RAID 1, and RAID 10 configurations for storage arrays, while RAID 5 and RAID 0+1 are not available.
