ROCK-SOLID PERFORMANCE
With upgraded power delivery and comprehensive cooling options to fuel the latest AMD Ryzen CPUs, plus support for faster memory and storage, TUF Gaming B550M-Plus WIFI II is the perfect foundation for your next high-core-count battle rig.
Power Design
DrMOS
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 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.
Stack Cool 3+
2-ounce copper layers draw heat away from critical components to keep them at their optimal operating temperatures and provide more headroom to push CPUs beyond stock speeds.
ProCool Socket
ENHANCED 8-PIN CONNETOR
– Extreme durability
– Prevent hotspots and connector failure
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 failure.
TUF COMPONENTS
TUF CHOKES
Certified military-grade TUF chokes deliver rock-steady power to the CPU, improving system stability.
TUF CAPACITORS
Proprietary capacitors provide up to 20% greater temperature tolerance and 5X-longer lifespan.
Digi+ VRM
The integrated DIGI+ VRM voltage-regulator module (VRM) is one of the finest in the industry, ensuring ultra-smooth and ultra-clean power delivery to the CPU at all times.
EASY PC DIY
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.
TUF PROTECTION
SafeSlot
SafeSlot is the PCIe slot reinvented by ASUS and engineered to provide superior retention and shearing resistance. Manufactured via a new insert-molding process, SafeSlot integrates fortifying metal for an inherently stronger slot, which is then firmly anchored to the PCB through additional solder points.
ESD guards
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.
KEYBOARDS AND MOUSE CONNECTORS
Additional on-circuit ESD transient-voltage-suppression.
VGA PROTECTION
Additional on-circuit ESD TVS diodes to protect VGA output functionality.
USB CONNECTORS
TVS diode for surface-mount and dual in-line package.
TUF LANGuard
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.
DRAM overvoltage protection
Onboard resettable fuses prevent overcurrent and short-circuit damage. This extends beyond I/O ports to DRAM to safeguard the lifespan of your system and connected devices.
Stainless-steel back I/O panel
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.
EASY CONFIGURATION
BIOS FlashBack™
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
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 of 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.
IMMERSIVE GAMING
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.
WiFi 6
The WiFi 6 module is compatible with the 802.11ax standard and pushes theoretical peak bandwidth up to an incredible 2.4 Gbps. Perhaps more importantly for power users, it’s optimized for more efficient operation on crowded networks with a lot of competing traffic. Pair your motherboard with ASUS WiFi 6 routers to fully experience the networking potential of WiFi 6.
EXCLUSIVE 2.5 GIGABIT ETHERNET
2.5G on-board Ethernet kicks your LAN connection up a notch with an up to 2.5X bandwidth improvement. Using your existing LAN cable, you can take advantage this networking upgrade to experience smoother, lag-free gaming, immediately stream high-resolution videos and enjoy faster file transfers.
MyASUS
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 enable the WiFi SmartConnect function to automatically connect to the wireless router with the best signal.
TWO-WAY AI NOISE CANCELATION
Two-way AI noise cancelation 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 only places a slight load on the CPU, ensuring minimal impact on gaming performance.
Gaming audio
DTS® Custom for gaming headsets
Hone your battle skills with exclusive DTS® Custom onboard audio. Utilizing advanced emulation techniques to create positional cues via stereo headphones, DTS® Custom takes onboard audio to a new frontier. With three presets ― Aerial, Soundscape, and Tactical ― for different genres, you’ll have a distinct advantage in every game.
