DURABLE. STABLE. RELIABLE.
This motherboard delivers rock-solid performance with unwavering gaming stability, thanks to military-grade components, an upgraded power solution, and a comprehensive set of cooling options.
When you build with a TUF Gaming motherboard, you also get the TUF Gaming Alliance benefits.
This is a collaboration between ASUS and trusted industry partners that simplifies building, ensures everything works properly, and ensures the components and case look good together.
The TUF Gaming B550M-Plus WIFI II is the perfect base for your next high-core-count battle rig because it has better power delivery and more cooling options to run the latest AMD Ryzen CPUs. It also supports faster memory and storage.
The onboard VRM of TUF Gaming B550M-Plus WIFI II utilizes 8+2 DrMOS power stages that combine high-side and low-side MOSFETs and the driver into a single package, delivering the power and efficiency that AMD Ryzen™ 5000 Series/5000 G-Series/4000 G-Series/3000 Series Processors demand.
Two-ounce copper layers pull heat away from important parts to keep them running at their best temperatures and give CPUs more room to go faster than their stock speeds.
longevity; it prevents hotspots and connector failures. Compared with traditional power inputs, ProCool sockets are built to tight specifications to ensure flush contact with PSU power lines. The resulting lower impedance helps to prevent hotspots and connector failures.
Certified military-grade TUF chokes deliver rock-steady power to the CPU, improving system stability.
Proprietary capacitors provide up to 20% greater temperature tolerance and a 5-times longer lifespan.
The integrated DIGI+ VRM voltage-regulator module (VRM) is one of the best in the business. It makes sure that power is always sent to the CPU in a very smooth and clean way.
TUF Gaming motherboards are designed to be easy to set up and configure just the way you want—even for first-time builders. The TUF Gaming Alliance ecosystem makes selecting compatible parts easy, while Armoury Crate software offers full control of system settings via a single dashboard. TUF Gaming motherboards give you everything you need to build your dream gaming rig without adding complexity.
SafeSlot is the PCIe slot reinvented by ASUS and engineered to provide superior retention and shear resistance. SafeSlot is made with a new process called "insert molding." It uses reinforcing metal to make a slot that is naturally stronger. The slot is then firmly attached to the PCB with more solder points.
ESD Guards prolong the life of components while preventing damage from electrostatic discharge, providing protection for up to +/- 10 kV of air discharge and +/- 6 kV of contact discharge - greatly surpassing the respective industry standards of +/- 6 kV and +/- 4 kV.
Additional on-circuit ESD transient-voltage-suppression.
Additional on-circuit ESD TVS diodes to protect VGA output functionality.
TVS diode for surface-mount and dual in-line package.
TUF LANGuard is a military-grade innovation that integrates advanced signal-coupling technology and premium surface-mounted capacitors to improve throughput, protecting the motherboard from lightning strikes and static electricity.
Onboard resettable fuses prevent overcurrent and short-circuit damage. This goes beyond I/O ports and includes DRAM to protect the life of your system and the devices you connect to it.
TUF Gaming motherboards have a corrosion-resistant stainless-steel back I/O panel bonded with chromium oxide to provide a 3X longer lifespan versus traditional panels. With this protective feature, TUF Gaming motherboards passed 72-hour salt fog testing, while other brands only passed 24-hour testing.
BIOS FlashBack™ is the simplest and safest (UEFI) BIOS update method. Simply drop the UEFI BIOS file onto a FAT32-formatted USB stick, plug it into the USB BIOS FlashBack™ port, and press the button. Updates can even be performed without having memory or a CPU installed.
Armoury Crate is a new software utility designed to give you centralized control of supported gaming products. From a single intuitive interface, Armoury Crate lets you easily customize RGB lighting and effects for every compatible device in your arsenal and synchronize them with Aura Sync for unified system lighting effects. You can also turn on the Two-Way AI Noise Cancelation function for crystal-clear in-game voice communication. The software also provides control over settings for a select and growing number of products, including keyboard and mouse preferences as well as laptop overclocking and fan speeds, making it easier to tune the look and feel of your system. Armoury Crate even features dedicated product registration and news areas to help you stay in touch with the gaming community.
TUF Gaming B550M-Plus WIFI II provides a complete, high-performance gaming package with a long list of features to improve your experience, including ultrafast networking for smoother online gameplay, pristine audio with positional cues for FPS gaming, and onboard RGB lighting that syncs with attached accessories to help you create a personalized gaming atmosphere.
The WiFi 6 module is compatible with the 802.11ax standard and pushes theoretical peak bandwidth up to an incredible 2.4 GB/s. Perhaps more importantly for power users, it has been optimized for more efficient operation on congested networks with a high volume of competing traffic.If you want to get the most out of WiFi 6, you should pair your motherboard with an ASUS WiFi 6 router.
2.5G on-board Ethernet improves your LAN connection by up to 2.5X in bandwidth.Using your existing LAN cable, you can take advantage of this networking upgrade to experience smoother, lag-free gaming, immediately stream high-resolution videos, and enjoy faster file transfers.
MyASUS offers a variety of support features to help you contact customer service, troubleshoot issues, and optimize product performance. You can also use MyASUS to turn on WiFi SmartConnect to automatically connect to the wireless router with the best signal.
Two-way AI noise cancellation software is exclusively featured on ASUS motherboards and supports 3.5 mm, USB, or Bluetooth headsets. The utility leverages a massive deep-learning database to preserve the sound of your voice while eliminating distracting keyboard clatter, mouse clicks, and other forms of environmental noise. And it doesn't put too much stress on the CPU, so it shouldn't affect how well games run.
DTS® Custom Onboard Audio allows you to hone your combat skills. Utilizing advanced emulation techniques to create positional cues via stereo headphones, DTS® Custom takes onboard audio to a new frontier. With three presets for different types of games—Aerial, Soundscape, and Tactical—you'll have a clear advantage in every game.
Sounds will feel like they are coming from ahead, as if you are floating above the game world. This is great for MOBA, RTA, strategy, and sports games.
This is the perfect audio envelope for MMOs, RPGs, action, and horror games—your ears will put you right in the middle of the action!
Shhh—is that an enemy just around the corner? DTS Custom emphasizes detail for stealthy play, so you'll detect and locate every footstep!
A well-tuned system deserves a matching aesthetic. ASUS Aura offers full RGB lighting control with a variety of functional presets for the built-in RGB LEDs as well as strips connected to the onboard RGB headers. And it can all be synced with an ever-growing portfolio of Aura-capable hardware.
The addressable Gen 2 header is now capable of detecting the number of LEDs on second-generation addressable RGB devices, allowing the software to automatically tailor lighting effects to specific devices. The new header also offers backward-compatibility with existing Aura RGB gear.
