## Long description

The ASRock X870 PRO RS motherboard for Socket AM5 delivers a high-performance platform for AMD Ryzen 7000, 8000, and 9000 series processors. Built on the AMD X870 chipset with an ATX form factor, it supports up to 256 GB of DDR5 memory across four DIMM slots and offers broad storage and expansion options including PCIe Gen5 M.2, multiple PCIe generations, and SATA III. The board integrates a 2.5 Gb/s LAN controller, USB4/USB 3.2 Gen2x2 Type-C connectivity, advanced VRM and cooling features, onboard RGB headers, and enhanced audio via Nahimic to meet the needs of gaming and content-creation systems.
Advantages
The motherboard features a 14+2+1 power phase VRM with Dr.MOS and durable 1000µF capacitors for stable CPU power delivery and improved overclocking headroom. An 8-layer PCB and hi-density power connectors increase efficiency and thermal performance under heavy loads. PCIe Gen5 Blazing M.2 and an enlarged, toolless M.2 heatsink provide high-speed storage support and simplified installation. Connectivity highlights include USB4 Type-C (40 Gbps), front-panel USB 3.2 Gen2x2 Type-C (20 Gbps), reinforced PCIe steel slot supporting PCIe 5.0, and a 2.5 Gb/s Dragon LAN port. Onboard Nahimic audio and Polychrome RGB headers enable configurable sound and lighting options.
Suitable for
High-performance gaming PCs using AMD Ryzen 7000/8000/9000 series CPUs
Content creation and video editing systems requiring fast storage and networking

How to use
Install the motherboard into an ATX-compatible chassis and connect the AM5 CPU, DDR5 memory modules, GPU and storage devices according to the manual. Use the hi-density 8-pin CPU and 24-pin ATX power connectors for reliable power. For NVMe performance, install a PCIe Gen5 M.2 SSD under the enlarged heatsink and secure it using the toolless mechanism. Enable Intel XMP or AMD EXPO profiles in BIOS to apply pre-tested DDR5 overclocking settings where supported. Update the BIOS using the EZ Flash utility if necessary before first boot to ensure CPU and memory compatibility.
Usage recommendations
Perform memory overclocking only with compatible DDR5 modules and consult the motherboard Memory QVL. Ensure adequate case airflow and use the provided heatsinks for M.2 and VRM areas when running sustained heavy workloads or overclocking. Update drivers and BIOS from the ASRock support site for best stability and feature support.
