ASRock B860 Pro RS Motherboard ATX with Intel 1851 Socket

Motherboard for computers with Intel processor, installed in socket 1851, and DDR5 memory.

10+1+1 Power Phase Design

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

Dr. MOS

Dr. MOS is the integrated power stage solution that is optimized for modern voltage reduction buck-set applications! Compared to traditional discrete MOSFETs, it intelligently provides higher current for each phase, thus offering 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.

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.

DIY-friendly design

The M.2 bottom heatsink is capable of effectively dissipating the heat of the M.2 SSD through the motherboard’s board, maximizing performance while maintaining system stability.

Aluminum Heatsink

The first thing that catches the eye is the optimized design of the aluminum heatsink. Heatsinks are vital for efficient 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 system stability and durability.

PWM/DC Fan Support

ASRock’s fan headers automatically detect whether the fans are running in DC or PWM mode, allowing users to adjust the fan curve and achieve quieter operation.

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.

Sound that matters

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

Improving communication quality

Powerful algorithms to ensure the best noise-free conversation, providing consistent voice levels regardless of the distance from your microphone. The Nahimic audio engine dynamically cleans the sound and removes interference noise and reduces voice variation. The result is better understanding and less fatigue.

Polychrome RGB

This motherboard features built-in RGB headers and addressable RGB headers 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 to the certified Polychrome RGB Sync accessories to create their own unique lighting effects.

Reinforced Steel Slot [PCIe 5.0 Edition]

The reinforced steel slot can support the PCI Express 5.0 standard. Various benefits include: 

Additional anchor points 
Stronger latch 
Ensure signal stability 
Make sure heavy graphics cards are well installed.
