## Long description

The ASRock B860M Pro RS WiFi is a micro-ATX motherboard designed for Intel LGA 1851 (Socket V1) processors. It supports DDR5 memory across four DIMM slots up to 256 GB, multiple M.2 and SATA III storage options, PCIe Gen5 and Gen4 expansion, integrated 2.5 Gb Ethernet and Wi‑Fi 6E, and a set of modern I/O including USB 3.2 Gen2x2 Type‑C. The board prioritizes stable power delivery and thermal management for reliable daily computing and enthusiast use.
Advantages
The board uses a 10+1+1 power phase design with Dr.MOS and hi‑density power connectors to provide smooth, high-current delivery for CPU overclocking and sustained performance. A 6‑layer PCB and aluminum heatsinks improve signal stability and thermal dissipation. Support for DDR5 XMP/EXPO, PCIe Gen5 Blazing M.2 slot, and reinforced PCIe steel slot increase compatibility with high‑speed memory, ultrafast SSDs and heavy graphics cards. Integrated Wi‑Fi 6E, Realtek 2.5 Gb LAN and Nahimic audio features cover modern networking and audio needs.
