Description

The ASRock B850 Micro ATX motherboard is designed to support AMD processors with the AM5 socket. This means you will need a compatible processor to install it properly.

With its Micro ATX size, this board is ideal for everyday use and can be installed in cases that support this form factor. Despite its more compact design, it offers ample features to meet your needs.

The ASRock B850 has adequate audio capabilities, supporting 7.1 audio channels for a rich listening experience. It is designed to support AMD processors from Zen 1 to Zen 4 generations, ensuring flexibility in your processor choice.

For memory, it supports the latest generation DDR5, offering speeds starting from 4000 MT/s for fast performance. You can use up to 4 SATA III 6Gb/s storage slots, which are ideal for SSD drives and ensure maximum performance.

Additionally, it features two PCI Express x16 slots—one 4.0 and one 5.0—allowing the installation of modern graphics cards and other expansion cards.

  • Processor socket: AM5
  • Size: Micro ATX
  • Audio channels: 7.1
  • Number of memory slots: 4
  • Supported processors: AMD (Zen, Zen 2, Zen 3, Zen 4)
  • Memory type: DDR5
  • Number of SATA III 6Gb/s: 4
  • PCI Express x16 4.0: 1
  • PCI Express x16 5.0: 1

VRM Design

8+1+1 Power Phase Design

  • Features robust components and delivers perfectly smooth power to the processor (CPU), ensuring enhanced performance for gamers.

Dr. MOS

  • Dr.MOS is the integrated power stage solution, optimized for synchronous buck-set down voltage applications. Compared to traditional discrete MOSFETs, it intelligently delivers higher current for each phase, thus offering improved thermal performance and superior efficiency.

Support for DDR5 XMP & EXPO

Drawing inspiration from the design philosophy "built for stability and reliability," ASRock makes no compromises on any detail. This motherboard is made with high-quality materials, allowing performance enthusiasts to enjoy the boost of overclocking DDR5 memory simply by enabling the pre-tested profiles. Make sure your memory modules support Intel® XMP or AMD EXPO™ and overclocking becomes accessible, satisfying, and absolutely effortless.

PCIe Gen5 Blazing M.2

The Blazing M.2 slot incorporates the latest PCI Express 5.0 standard, offering double the bandwidth compared to the previous generation. With an impressive transfer speed of 128Gb/s, it is ready to fully unleash the potential of future ultra-fast SSD drives.

Aluminum Heatsink

The first thing that catches the eye is the optimized design of the Aluminum Heatsink. Heatsinks are crucial for effective heat dissipation, especially during heavy workloads such as gaming or demanding productivity tasks. A motherboard built with reinforced heatsinks can efficiently manage thermal performance, thus ensuring the stability and durability of the system with absolute ease.

WiFi 7 (802.11be)

The latest WiFi 7 technology offers extreme wireless internet speeds and low latency, with higher throughput and Multi-RU and Puncturing technologies. The new WiFi 7 (802.11be) technology is capable of accelerating cloud gaming, 8K video streaming, and video calls.

Dragon 2.5 Gb/s LAN

The intelligent 2.5Gb/s LAN platform is designed for maximum network performance, meeting the demanding needs of home networks, content creators, online gamers, and high-quality streaming. Boosting network performance by up to 2.5 times compared to standard gigabit Ethernet, you will enjoy a faster and uncompromised connectivity experience for gaming, file transfers, and backup downloads.
