Get ample connectivity without skimping on performance with the ROG Strix B550-A Gaming AM4 ATX Motherboard from ASUS. Designed for use with CPUs using the AM4 socket, this board features the AMD B550 chipset. Install up to 128GB of dual-channel DDR4 RAM across four slots, with speeds up to 5100 MHz supported when overclocking. Storage drives can be installed using six SATA III connectors or two M.2 slots. Up to two graphics cards can be installed using PCIe 4.0 x16 and PCIe 3.0 x16 slots, with support for 2-way AMD CrossFireX. Other adapter cards can be installed in three PCIe 3.0 x1 slots.

A rear I/O panel sports a USB 3.2 Gen 2 Type-A and Type-C port, as well as four USB 3.2 Gen 1 and two USB 2.0 Type-A ports. Connect displays using the DisplayPort or HDMI outputs, or connect audio using a S/PDIF port or five 3.5mm jacks. An RJ45 port supports 2.5 Gigabit Ethernet, while a BIOS flashback button is also present. The ASUS ROG Strix B550-A Gaming AM4 ATX Motherboard utilizes the SupremeFX S1220A audio codec and supports Windows 10 64-bit operating systems.

Key Features

AMD B550 Chipset

This motherboard uses the AMD B550 chipset and is compatible with AMD CPUs using the AM4 socket.

PCIe 4.0-Ready

The ROG Strix B550-A Gaming features two M.2 slots, one of which supports the PCIe 4.0 standard to provide optimum storage and data speeds via the 3rd Gen AMD Ryzen platform. Both M.2 slots support up to the type 22110 socket and NVM Express RAID for a performance boost.

ProCool Power Connector

The ProCool socket is built to ensure flush contact with the PSU powerlines, enabling lower impedance and efficient heat dissipation.

DIGI+ Power Control

ASUS DIGI+ Power Control allows you to tune VRAM and DRAM voltage for optimal system efficiency, stability, and performance.

Alloy Chokes and Capacitors

Alloy chokes and capacitors are designed to resist extreme temperatures.

Six-Layer PCB

This layered PCB dissipates heat around the VRM, improving overall system stability while providing overclocking headroom.

Intel 2.5 Gigabit Ethernet

Onboard 2.5 Gigabit Ethernet gives your wired connection a boost, with speeds that are 2.5 times faster than standard Ethernet connections for speedy file transfers, lag-free gaming, and high-res video streaming.


Built-in ROG SupremeFX audio technology provides accurate audio and two front-panel op-amp outputs for gaming headsets.

Audio Cover

Effective shielding against electromagnetic interference preserves the integrity of audio signals for uncompromised sound quality.

Audio-Line Shielding

This shielding blocks electromagnetic interference from the motherboard or add-ons to provide cleaner audio.

Dual Op-Amps

Two onboard op-amps provide adequate power for headphone impedances from 32 to 600 ohms.

AI Noise-Canceling Microphone

AI noise-canceling microphone software on ROG Strix motherboards supports 3.5mm, USB, or Bluetooth headsets. Utilizing a deep-learning database, this utility preserves the sound of your voice while eliminating distracting keyboard clatter, mouse clicks, and other forms of environmental noise. And it only places a slight load on the CPU, ensuring minimal impact on gaming performance.

Sonic Studio III

Sonic Studio supports HRTF- or head-related transfer function-based virtual surround for VR headsets. The Sonic Studio interface also offers a range of EQ options and one-click presets, allowing you to tailor acoustics to suit personal preferences or the characteristics of your headset.

DTS: Sound Unbound

ROG Strix B550 series motherboards are pre-loaded with the DTS Sound Unbound app. By leveraging Windows Sonic spatial technology, DTS Sound Unbound delivers audio in a virtual 3D space. Requiring in-game support, this function allows users to choose between stereo, surround, or spatial sound according to personal tastes.

VRM Cooling

A MOS heatsink provides a large contact area for MOSFETs and chokes, while the thermal pad helps transfer heat from the inductor and phase array to the heatsink.

Pre-Mounted I/O Shield

The I/O shield is finished in matte black and comes pre-mounted to make it easy to install on the motherboard.


Four onboard LEDs indicate power status or potential problems with the CPU, memory, graphics card, or boot device, allowing for quick diagnosis.


The reinforced ASUS SafeSlot is designed to provide strong PCIe device retention and shearing resistance.

BIOS FlashBack

Users can place a BIOS file onto a FAT32-formatted USB drive and simply plug it into the USB BIOS FlashBack port and press a button to update the UEFI BIOS. Updates can be made even if memory or CPU aren’t present.


Advanced Mode

When you’re ready for a deeper dive into the configuration of your system, delve into the UEFI’s Advanced mode and take complete control. Each section is intuitively organized, and a built-in search feature makes it easy to find the options you need. Advanced functions are coded with the intelligence to adapt to your settings, and when you’re ready to take charge, parameters have the granularity to dial in performance just the way you want.

EZ Mode

Designed to simplify setup, EZ mode presents all the vital settings and stats on a single page. With guided wizards, drag-and-drop functionality, and one-click application of important settings, your rig will be up and running in no time.

AI Networking

GameFirst VI

GameFirst VI features AI-enhanced identification and boost technology to ensure faster and smarter network optimization.


GameFirst VI analyzes your usage patterns and the digital signatures of your applications and compares them to a database of over 200,000 apps. The database is regularly updated to ensure that apps are recognized.


GameFirst VI switches application priority and adjusts bandwidth accordingly, depending on the situation. When gaming, it accelerates and prioritizes game packets for online gameplay, even when you’re streaming high-quality video to your audience or transferring large files.


An intuitive graph gives you an overview of the network in real time. Simply click on the tab to view current bandwidth usage of each application, geolocation status of each network connection, and an analysis of each Wi-Fi channel.
