ASRock B860 PRO-A WiFi ATX Motherboard

The ASRock B860 PRO-A WiFi delivers reliable performance and enhanced stability for Intel Core Ultra Processors (Series 2) with LGA1851 socket support. This ATX motherboard combines professional-grade components with user-friendly features for demanding computing applications.

Power Delivery and Performance

Built with a 10+1+1+1+1 power phase design featuring Dr.MOS technology for VCore, GT, and SA, this motherboard ensures completely smooth power delivery to the CPU. The Hi-Density Power Connectors withstand higher currents compared to traditional connectors, providing system stability during intensive workloads. Support for DDR5 memory with Intel XMP profiles enables overclocking up to 8666+ MHz across four DIMM slots, with a maximum capacity of 256GB.

Expansion and Storage

The B860 PRO-A WiFi features one PCIe 5.0 x16 slot and one PCIe 4.0 x16 slot for graphics cards and expansion cards. Storage options include four SATA III ports and three M.2 slots: one Blazing M.2 supporting PCIe Gen5 x4 with 128Gb/s transfer speeds, and two Hyper M.2 slots supporting PCIe Gen4 x4. RAID 0, 1, 5, and 10 configurations are supported for SATA devices.

Connectivity Features

Integrated WiFi 6E 802.11axe technology extends to the 6GHz spectrum band, delivering enhanced bandwidth and lower latency equivalent to 5G networks. The Realtek 2.5Gb/s LAN provides 2.5X the bandwidth of standard gigabit ethernet. USB connectivity includes one USB 3.2 Gen2x2 Type-C port delivering 20Gbps transfer rates, plus multiple USB 3.2 Gen1 and USB 2.0 ports across front and rear panels. Dual graphics outputs via HDMI and DisplayPort 1.4 accommodate integrated graphics configurations.

Thermal Management

Aluminum heatsinks manage thermal performance during heavy workloads. PWM/DC fan headers automatically detect fan modes, with seven total fan headers including two CPU fans, four chassis fans, and one AIO pump fan. The Fan-Tastic Tuning function enables automatic duty detection and customizable fan curves through a visualized interface.

DIY-Friendly Features

The reinforced PCIe 5.0 steel slot provides structural support for heavy graphics cards. BIOS Flashback allows firmware updates using only a USB drive and power supply, without requiring CPU or RAM installation. Auto Driver Installer pre-installs LAN drivers for simplified setup. Polychrome RGB headers and addressable RGB headers support compatible LED devices with SignalRGB integration for unified lighting control.

Realtek ALC897 7.1 CH HD Audio Codec delivers high-definition audio output. The motherboard includes I/O shield, two SATA data cables, and two WiFi antennas. Backed by a 3-year replacement warranty.
