ASRock B860M PRO-A WiFi Motherboard - Intel LGA1851 Platform

The ASRock B860M PRO-A WiFi is a Micro ATX motherboard built on the Intel B860 chipset, designed to support Intel Core Ultra Processors (Series 2) with the LGA1851 socket. This motherboard delivers reliable performance for daily computing, content creation, and gaming through its Pro-A series design philosophy focused on stability, durability, and efficiency.

Power Delivery and Memory Support

Featuring a 10+1+1+1+1 power phase design with Dr.MOS technology for VCore, GT, and SA, this motherboard provides stable power delivery even under demanding workloads. The 6-layer PCB construction ensures clean signal traces and efficient power distribution. Four DDR5 DIMM slots support dual-channel memory configurations up to 8666MHz (OC) with a maximum capacity of 256GB, compatible with both Intel XMP and AMD EXPO profiles for easy overclocking.

Expansion and Storage Options

The expansion capabilities include one PCIe 5.0 x16 slot with reinforced steel construction and one PCIe 4.0 x4 slot. Storage options are comprehensive with four SATA III ports and three M.2 slots: one Blazing M.2 supporting PCIe Gen5 x4 for transfer speeds up to 128Gb/s, and two Hyper M.2 slots with PCIe Gen4 x4 support. RAID 0, 1, 5, and 10 configurations are supported across SATA devices.

Connectivity Features

Network connectivity includes 802.11axe WiFi 6E with extended 6GHz band support, Bluetooth 5.3, and Realtek 2.5G LAN for wired connections. The rear I/O panel offers one USB 3.2 Gen2x2 Type-C port delivering 20Gbps transfer speeds, three USB 3.2 Gen1 Type-A ports, and two USB 2.0 ports. Front panel connectivity includes one USB 3.2 Gen1 Type-C header and additional USB 3.2 Gen1 and USB 2.0 headers. Display outputs consist of one HDMI and one DisplayPort 1.4 connector for integrated graphics support.

Cooling and Audio

Aluminum heatsinks provide thermal management for critical components, while multiple fan headers support both PWM and DC modes. The Fan-Tastic Tuning utility enables automatic fan curve optimization. Audio is handled by the Realtek ALC897 codec delivering 7.1 channel HD audio output.

User-Friendly Features

BIOS Flashback functionality allows BIOS updates using only a USB drive and power supply, without requiring CPU, RAM, or other components. The Auto Driver Installer pre-installs LAN drivers for simplified setup. Polychrome RGB and addressable RGB headers enable customization of compatible LED devices, with SignalRGB support for unified lighting control across multiple peripherals.

The package includes an I/O shield, two SATA data cables, and two WiFi antennas. Backed by a 3-year replacement warranty, the B860M PRO-A WiFi provides a solid foundation for Intel's latest LGA1851 platform.
