Description

Description

The ASRock B860M Pro RS motherboard is aimed at users who desire a reliable and efficient computer for everyday tasks, offering stability, durability, and efficiency. It supports Intel Core Ultra processors (Arrow Lake-S) and DDR5 memory up to 8666 MHz (OC), providing high performance for daily use.

10+1+1 Power Phase Design

It features durable components and completely smooth power delivery to the CPU. Additionally, it offers unparalleled overclocking capabilities and enhanced performance with the lowest temperature, suitable for advanced gamers.

Dr. MOS

Dr. MOS is the integrated power stage solution optimized for modern buck-set voltage reduction applications! Compared to traditional discrete MOSFETs, it intelligently provides higher current for each phase, thus delivering improved thermal results and superior performance.

High-Density Power Connector

CPU overclocking requires higher current. ASRock's Hi-Density Power Connectors are designed to withstand higher currents compared to traditional CPU and ATX power plugs, providing a more stable system and reducing the risk of fire during intense overclocking.

PCB 6 layers

The 6-layer PCB provides stable signal traces and power shapes, offering lower temperature and higher energy efficiency for memory overclocking! Thus, it is able to support the latest memory modules with the most extreme memory performance!

Support for DDR5 XMP & EXPO

ASRock, which originates from the design concept "built for stable and reliable", makes no compromises on any detail. This motherboard is made with high-quality materials, and enthusiastic users can enjoy boosting DDR5 memory overclocking performance by enabling the pre-tested profiles. Ensure that the memory modules are capable of Intel® XMP/AMD EXPO™ and overclocking can be made so accessible, satisfying, and sweat-free.

PCIe Gen5 Blazing M.2

Blazing M.2 hosts the latest PCI Express 5.0 standard for double the bandwidth compared to the previous generation, with an amazing transfer speed of 128Gb/s, it is ready to unleash the full potential of future ultra-fast SSDs.

Aluminum cooler

The first thing that catches the eye is the optimized design of the aluminum heatsink. Heatsinks are vital for effective heat dissipation, especially during heavy workloads such as gaming or productivity tasks. Motherboards built with heatsinks can effectively manage thermal performance and, therefore, effortlessly ensure the system's stability and durability.

Dragon 2.5 Gb/s LAN

The smart LAN 2.5Gb/s platform is built for maximum networking performance for the demanding requirements of home networking, content creators, online gamers, and high-quality streaming media. Enhancing networking performance up to 2.5 times the bandwidth compared to standard Gigabit Ethernet, you will enjoy the fastest and uncompromised connectivity experience for gaming, file transfers, and backups.

USB 3.2 Gen2x2 20Gbps Type-C

The latest version USB 3.2 Gen2x2 Type-C provides a data transfer rate of up to 20 Gbps, which is 2 times faster than the previous generation, offering a high-speed data transfer interface with a reversible USB Type-C design that fits the plug in any way.

Front USB 3.2 Gen1 Type-C

The front USB 3.2 Gen1 Type-C header provides a data transfer rate of up to 5 Gbps and next-generation reversible USB design on the front side of the computer case.

Nahimic Audio

Whether you use headphones, earphones, external or internal speakers, via USB, Wi-Fi, analog output, or even HDMI, Nahimic Audio offers you the most immersive listening experience, vivid and rich in detail.

Polychrome RGB

It features built-in RGB headers and an addressable RGB header that allow the motherboard to connect with compatible LED devices, such as strips, CPU fans, coolers, cases, and so on. Users can also synchronize the RGB LED devices with certified Polychrome RGB Sync accessories to create their own unique lighting effects.

BIOS Flashback

Get the most convenient BIOS flashing with a simple click. Users can easily achieve the latest BIOS support with USB and power supply, No CPU, RAM, or other components required.
