## Long description

The ASRock B850 Pro RS WiFi (Socket AM5, ATX) motherboard is designed for stability, durability and efficient daily computing. It supports AMD Ryzen 7000/8000/9000 series processors, DDR5 memory up to 256 GB across four DIMM slots, multiple M.2 and SATA III storage options with RAID 0/1/10, 2.5 GbE LAN and Wi‑Fi 6E for high-speed connectivity. The board includes reinforced PCIe 5.0 steel slot, extensive M.2 cooling, and a PWM/DC-aware fan solution to maintain system stability under heavy loads.
Advantages
The motherboard features ASRock Hi‑Density power connectors and a 14+2+1 power phase design for stable CPU power delivery and improved overclocking capability. An 8‑layer PCB lowers operating temperatures and enhances signal integrity for memory overclocking. Multiple high‑speed M.2 options (PCIe Gen5 and Gen4) and enlarged heatsinks with anti‑drop screw simplify installation and improve SSD thermal performance. Built‑in Wi‑Fi 6E, 2.5 Gb/s LAN and abundant USB ports including a front USB 3.2 Gen2x2 Type‑C header deliver modern connectivity. Nahimic audio and Polychrome/SignalRGB support provide flexible audio and lighting control.

How to use
Install the motherboard into an ATX chassis and connect the power supply using the Hi‑Density CPU and 24‑pin ATX connectors. Populate memory modules into the DDR5 DIMM slots and enable Intel XMP or AMD EXPO/ pre‑tested profiles in BIOS to apply memory overclocking settings if supported by your modules. Mount M.2 SSDs beneath the provided M.2 heatsinks and secure using the anti‑drop screw design; larger M.2 devices benefit from the bottom heatsink and XXL aluminum heatsink for improved thermal performance. Connect cooling fans to the PWM/DC headers and use ASRock A‑Tuning Fan‑Tastic Tuning in software to auto‑detect minimum fan duties and customize fan curves.
Usage recommendations
Use certified Intel XMP or AMD EXPO memory modules for reliable DDR5 overclocking, keep M.2 SSDs under their heatsinks for sustained performance, and update BIOS via BIOS Flashback when changing to a new CPU generation to ensure full compatibility. For optimal cooling, configure fan profiles through the motherboard utilities and ensure good case airflow.
