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.

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.

SupremeFX

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.

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.

Q-LEDs

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

SafeSlot

The reinforced ASUS SafeSlot is designed to provide h3 PCIe device retention and shearing resistance.

BIOS FlashBack
