Enhance your computing experience with the ASRock B550 Pro4 AM4 ATX Motherboard. Powered by the AMD B550 chipset, this ATX motherboard is designed for gamers and enthusiasts, supporting fifth- and third-generation AMD Ryzen processors with the AM4 socket for high-end video games and content creation. The chipset takes full advantage of the large PCIe 4.0 data bandwidth to handle demanding tasks such as 4K live streaming, video editing, and gaming at high settings.

Up to 128GB of dual-channel ECC or non-ECC unbuffered DDR4 RAM, reaching 4733 MHz when overclocked, can be installed across four memory slots to improve the system's multitasking capabilities and speed. The motherboard also supports two M.2 SSDs alongside up to six SATA III storage drives, which can be put into RAID 0, 1, or 10 configurations. Its PCIe x16 slots can accommodate dedicated graphics cards with support for Quad-GPU and 2-Way AMD CrossFireX configurations. There are also two PCIe 3.0 x1 slots available for compatible expansions. Alternatively, you can take advantage of AMD Ryzen processors with integrated graphics by connecting monitors to the motherboard's HDMI 2.1 and VGA ports.

Connect peripherals such as mice and keyboards to the four 5 Gb/s USB 3.2 Gen 1 Type-A ports while reserving the USB 3.2 Gen 2 Type-A and Type-C ports for transferring up to 10 Gb/s with compatible devices. The B550 Pro4 connects to compatible networks via its built-in Gigabit Ethernet port, providing you with the bandwidth needed for online games, 4K video streaming, and live stream broadcasts. You can install a separate Wi-Fi module into the available M.2 E Key slot for wireless network connections. Other features include a Nahimic Audio-enhanced Realtek ALC1200 7.1-channel audio codec that delivers immersive experiences while the ASRock Polychrome RGB lighting headers allow you to customize a variety of dazzling LED lighting effects and sync them with compatible peripherals to match your game, mood, or style. Windows 10 64-bit is required to take advantage of all the motherboard's features.

PCIe 4.0 Memory Bandwidth

The ASRock Pro4 pairs socket AM4 AMD Ryzen processors with high PCIe 4.0 memory bandwidth through the B550 chipset for maximum performance.

Storage and Memory

  • Two M.2 slots are available, supporting up to type 22110 NVMe PCIe and SATA SSDs.
  • Six SATA III ports are available for hard drives and 2.5" SSDs.
  • Supports RAID 0, 1, and 10.
  • Up to 128GB of dual-channel ECC and non-ECC unbuffered DDR4-4733 (OC) memory can be installed across four slots.

Electrical Performance

The motherboard has an 8-phase power design that uses high-quality 50A alloy chokes alongside durable capacitors deliver power to critical components such as the CPU.

2 oz Copper PCB

This motherboard's inner layers include 2 oz of copper to efficiently provide stable power to components at lower temperatures when overclocking.

AMD CrossFireX

Is one graphics card not enough? AMD's CrossFireX works with compatible motherboards and allows you to install and combine two of the same GPUs to split the processing load and render graphics with improved frame rates and image quality for supported applications. This motherboard supports Quad-GPU and 2-Way CrossFireX configurations.

USB 3.2 Gen 2

Doubling the speed of its predecessor, USB 3.2 Gen 2 features a maximum throughput of 10 Gb/s when used with compatible devices.

Durable Design

  • Dedicated M.2 SSD heatsinks help to ensure optimal temperatures and avoid speed throttling.
  • Steel reinforced PCIe connectors feature extra anchor points and strong latches, adding stability for heavy graphics cards.
  • The XXL aluminum alloy heatsinks help to draw heat away from critical components for optimal performance and stability.
  • The PCB has a high-density glass fabric design that reduces gaps between layers to protect against electrostatic discharge and humidity.
  • Comprised of various technologies, ASRock Full Spike Protection helps to prevent damage to your motherboard's components from unexpected voltage spikes.

Integrated Graphics

Alongside the VGA connector is an HDMI 2.1 port, which supports 4K monitors and allows you to take advantage of AMD Ryzen CPUs that have integrated graphics.

Fast Network Connectivity

  • Gigabit Ethernet connectivity provides high-speed connections to compatible wired devices.
  • A Wi-Fi module can be installed into the M.2 E Key slot to connect with compatible wireless networks.

  • Immersive Audio

    The integrated Realtek ALC1200 audio technology delivers detailed sound with 7.1-channel playback. Nahimic Audio enhancements are designed to deliver rich and engaging listening experiences through both headphones and external speakers.

    Polychrome RGB Lighting

    ASRock Polychrome technology allows you to connect, customize, and control lighting equipment such as RGB LED light strips on the onboard RGB headers. You can choose from a variety of lighting presets, which can be synchronized with capable peripherals such as keyboards, mice, CPU coolers, and more. The addressable RGB header can detect the number of LEDs on a compatible device to further tailor the lighting effects.
