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.

*Specifications vary by models.

COOLING

1. VRM HEATSINK
A large, high-mass heatsink with extensive surface that covers the VRM and choke areas improves heat dissipation.

THERMAL PAD
High-quality thermal pads help transfer heat from the inductor and phase array to the heatsink.

2. M.2 HEATSINK
The M.2 heatsink keeps the M.2 SSD at the optimum operating temperature for consistent performance and reliability.

TUF Gaming B550M-Plus WIFI II features comprehensive fan controls that can be configured via Fan Xpert 2+ utility or via the award-winning ASUS UEFI BIOS.

Multiple temperature sources

Each header can be set to monitor and react to three user-configurable thermal sensors for workload-based cooling, and all settings can be easily managed by Fan Xpert 2+ or via the UEFI.

4-pin PWM/DC fan

All onboard chassis fan headers support auto-detection of PWM or DC fans.

Smart protection

A dedicated integrated circuit protects each fan header from over-temperature and overcurrent.

STORAGE

PCIe 4.0 M.2 (up to 64 Gbps)

TUF Gaming B550M series motherboards support PCIe 4.0 M.2 slot and provides NVMe SSD RAID support for an incredible performance boost. Create a RAID configuration with up to PCIe 4.0 storage device to enjoy the fastest data-transfer speeds on the AMD Ryzen™ 5000 Series/ 3000 Series Processors platform.

*Actual transmission speed will be lower than theoretical maximum speed.

**The M.2_1 supports PCIe 4.0 and the M.2_2 supports PCIe 3.0.C

CONNECTIVITY

USB 3.2 Gen 2 Type-A & Type-C®

Numerous USB ports support gaming rigs loaded with peripherals, including a USB Type-A and a Type-C® connectors with fast USB 3.2 Gen 2 connectivity for compatible cases.

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.
