Engineered with military-grade components, an upgraded power solution and a comprehensive set of cooling options, this motherboard delivers rock-solid performance with unwavering gaming stability.

When you build with a TUF Gaming motherboard, you also benefit from the TUF Gaming Alliance — an ASUS collaboration with trusted industry partners that ensures easier building, best compatibility, and complementary aesthetics from components to case.

ROCK-SOLID PERFORMANCE
With upgraded power delivery and comprehensive cooling options to fuel the latest AMD RyzenTM CPUs, plus support for faster memory and storage, TUF GAMING B550M-E is the perfect foundation for your next high-core-count battle rig.

Power Design
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.

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.

Cooler by design
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.

3. PCH HEATSINK
Mass and surface area of the heatsink is carefully designed and balanced to maximize thermal dissipation for the latest AMD B550 chipset.

COMPREHENSIVE FAN CONTROLS
TUF Gaming B550M-E features comprehensive fan controls that can be configured via Fan Xpert 2+ utility or via the award-winning ASUS UEFI BIOS.

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 AMD Ryzen™ 5000 Series/ 3000 Series processors.

USB 3.2 Gen 2 Type-A
Extensive USB support ensures connections to a wide array of peripherals. TUF GAMING B550M-E series motherboards include two USB 3.2 Gen 2 Type-A ports that deliver increased bandwidth and transmission speeds of up to 10 Gbps.

USB 3.2 GEN 1 TYPE–C® CONNECTOR
Numerous USB ports support gaming rigs loaded with peripherals, including a front-panel USB Type-C® connector with fast USB 3.2 Gen 1 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.

Build with confidence
TUF Gaming Alliance is a collaboration between ASUS and trusted PC-component brands to ensure compatibility with a wide range of parts, such as PC cases, power supplies, CPU coolers, memory kits and more. With more partnerships and components being added regularly, the TUF Gaming Alliance will continue to grow even stronger.

TUF PROTECTION
SAFESLOT CORE+
SafeSlot Core+ is the ASUS-exclusive PCIe slot fortified with a one-piece stainless-steel brace that shields the slot to protect it from damage. The metal cover is tightly secured to the slot with hooks, and the entire assembly is firmly anchored to the PCB with strengthened solder points to provide a secure foundation for heavyweight graphics cards.

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.

IMMERSIVE GAMING
TUF Gaming B550M-E 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.

Turbo LAN
NETWORK-OPTIMIZATION SOFTWARE FOR CUSTOMIZABLE PACKET PRIORITIZATION
Turbo LAN is a network-optimization software for customizable packet prioritization. With cFosSpeed traffic-shaping technology, it allows you to configure application priority via an intuitive interface, and reduces network lag.

1. ONE CLICK TURBO
Adjust the network transmission priority by one click!
2. AUTO DETECT GAME LIST
Turbo Lan will detect every game in system, and add in list automatically.

Outshine the Competition
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.

Addressable Gen 2 RGB Header
The addressable Gen 2 RGB headers are now capable of detecting the number of LEDs on second-gen 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.
