Product Overview

The ASRock B860M Pro-A WiFi is a Micro ATX motherboard built on the Intel B860 chipset for LGA1851 Arrow Lake Core Ultra processors. It stands out with four DDR5 slots supporting up to 256 GB, three M.2 slots, a PCIe 5.0 x16 slot, and a rear USB-C port running at 20 Gbps, plus built-in Wi-Fi 6E, Bluetooth 5.3 and 2.5 Gb Ethernet.

This board suits a compact to mid-sized gaming or everyday PC built around a Core Ultra 3, 5, 7 or 9 CPU, where you want fast storage and wireless connectivity without the cost of a higher-tier chipset. Six 4-pin PWM fan headers and three addressable RGB headers give flexibility for cooling and lighting. Video outputs (HDMI and DisplayPort) only work with a CPU that has integrated graphics. A BIOS update may be needed for the newest processors.
