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.
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.
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.
Effective shielding against electromagnetic interference preserves the integrity of audio signals for uncompromised sound quality.
This shielding blocks electromagnetic interference from the motherboard or add-ons to provide cleaner audio.
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.
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 h3 PCIe device retention and shearing resistance.
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.
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.
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.
