## Long description

The ASRock X870 Steel Legend WiFi is an ATX motherboard with an AMD X870 chipset and Socket AM5, designed for high-performance desktop systems using AMD Ryzen 7000/8000/9000 series processors. It supports up to 256 GB of DDR5 memory across four DIMM slots, PCIe 5.0 for next-generation graphics and NVMe storage, integrated Wi‑Fi 7 and a 2.5 Gb/s LAN port, and a robust power delivery and cooling layout aimed at stable operation under heavy loads.
Advantages
The motherboard implements a 14+2+1 power phase design with Dr.MOS and hi-density power connectors to provide smooth, efficient CPU power and improved overclocking headroom. An 8-layer PCB and enlarged aluminum M.2 heatsink support thermal stability, while 20K black capacitors with 1000µF capacitance improve load-bearing capability and reduce ripple. Features such as PCIe Gen5 M.2 support, USB4 Type-C, front-panel USB 3.2 Gen2x2 Type-C header, Nahimic audio enhancements and Polychrome RGB headers make the board suitable for both demanding gaming and creative workloads.
Suitable for
High-performance gaming PCs with AMD Ryzen AM5 processors
Content creation and productivity rigs requiring fast storage and memory
Systems that need Wi‑Fi 7 and 2.5 GbE networking
Overclocking-oriented builds using DDR5 XMP/EXPO profiles
PCs using PCIe 5.0 graphics cards and Gen5 NVMe SSDs

How to use
Install the motherboard into an ATX-compatible case and connect the AMD AM5 CPU, DDR5 memory modules, GPU and storage devices following the motherboard manual. Use the hi-density 8-pin CPU power connector and 24-pin ATX connector for stable power delivery. Enable Intel XMP or AMD EXPO profiles in the UEFI/BIOS to apply tested DDR5 overclocking settings for supported memory modules. For NVMe SSDs, install compatible PCIe Gen5 drives into the designated M.2 slots and ensure the M.2 heatsink is properly engaged using the toolless mechanism.
Usage recommendations
Use quality, AM5-compatible cooling and a PSU with sufficient wattage and stable rails when overclocking; update the motherboard BIOS to the latest version for optimal CPU and memory compatibility, and verify that memory modules support XMP/EXPO profiles before enabling them.
