Power Design

Driver & MOSFET - 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.

Power Connector
ProCool Socket - Enhanced 8-Pin Connector
• 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.

System Stability - 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 52% wider temperature tolerance and 2.5X-longer lifespan.

Controller - 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.

Cooling

Cooler by Design - 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.

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

Comprehensive Fan Controls
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.
