The ASRock B850 Challenger Wi-Fi is built around the AM5 socket with a single CPU socket and B850 chipset compatibility, housed in a standard ATX form factor measuring 305 mm wide and 244 mm tall. It supports Wi-Fi across five generations — from Wi-Fi 4 through to Wi-Fi 7 (802.11be) — along with Bluetooth 5.4, though aptX audio codec support is not included. The board features RGB lighting, a dual BIOS setup for added resilience, and is described as easy to overclock, while manual CMOS reset is not available. Video output is handled via an HDMI 2.1 port, though there is no integrated graphics or integrated CPU on the board itself. A three-year warranty is included, and the board does not support ECC or integrated processor configurations.
This 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 enthusiasts looking to push memory performance beyond standard rated speeds. ECC memory is not supported on this board.
The rear I/O panel provides a total of nine USB ports: one USB 3.2 Gen 2 Type-A port, four USB 3.2 Gen 1 Type-A ports, and four USB 2.0 ports, alongside at least one USB Type-C connector. Higher-speed options such as USB 3.2 Gen 2x2, USB 4, Thunderbolt 3, and Thunderbolt 4 are not present. Video output is limited to a single HDMI port, with no DisplayPort, DVI, or VGA outputs available. Network connectivity is covered by one RJ45 port, and there are no eSATA or PS/2 ports on this board.
Internal connectivity is well-covered, with headers supporting four USB 3.2 Gen 1 ports, four USB 3.0 ports, four USB 2.0 ports, and one USB-C 3.2 Gen 2 port — all available through case expansion. Storage options include four SATA 3 connectors and two M.2 sockets for NVMe or SATA-based drives, while SATA 2, mSATA, and U.2 connectors are absent. The board also includes six fan headers for cooling management and a TPM connector for security module support.
The board offers four PCIe slots in total: one PCIe 5.0 x16 slot and one PCIe 4.0 x16 slot for full-size cards, plus two PCIe x1 slots for smaller expansion cards. There are no PCIe 2.0, PCIe 3.0, PCIe x4, PCIe x8, or legacy PCI slots present.
Audio output supports a 7.1-channel configuration through three analog audio connectors on the rear panel. There is no S/PDIF Out port available on this board.
The board supports RAID 0, RAID 1, and RAID 10 configurations for flexible storage setup, whether the priority is performance, redundancy, or a combination of both. RAID 5 and RAID 0+1 are not supported.
