Overview

ASUS Prime series is expertly engineered to unleash the full potential of 3rd Generation AMD Ryzen platform. Boasting a robust power design, comprehensive cooling solutions and intelligent tuning options, Prime B550 series motherboards provide daily users and DIY PC builders a range of performance tuning options via intuitive software and firmware features.

Tune It Your Way

Comprehensive controls form the foundation of the ASUS Prime series. The Prime B550 motherboard packs flexible tools to tune every aspect of your system, enabling you to tweak performance settings to perfectly match the way you work – maximizing your productivity.

Intelligent Control

EPU

All-around Energy Efficiency

With the Energy Processing Unit (EPU), you’ll enjoy system-wide power savings. The EPU automatically optimizes power consumption and maximizes savings with Away mode.

Fan Xpert 2+

Flexible Air- and Liquid-Cooling Controls

Fan Xpert 2+ software provides comprehensive control over system fans. Auto-Tuning mode intelligently configures all parameters with a single click. There’s also an Extreme Quiet mode that reduces chassis fan speeds to below the default minimum to keep your system whisper-quiet when performing light tasks. Fans can also be controlled via the UEFI BIOS.

Digi+ VRM Control

Precise Digital Power Control

The Digi+ voltage-regulator module (VRM) delivers real-time control over voltage droop, automatically switching frequency and power-efficiency settings. It also allows you to fine-tune your CPU for ultimate stability and performance.

UEFI BIOS

The renowned ASUS UEFI BIOS provides everything you need to configure, tweak and tune your system. It offers intelligently simplified options for PC DIY beginners, as well as comprehensive features for seasoned veterans.

Advanced Mode

Advanced Tuning for Serious Tweakers

An intuitive Advanced mode offered via the UEFI lets you take complete control. A built-in search feature makes it easy to find options, and various Advanced functions let you intelligently make nuanced adjustments so you can dial in performance just the way you want. 

  • Search Function - Quickly and easily find the option or setting you need.
  • ASUS User Profile - Port configuration settings between different BIOS versions or share them with friends.

EZ Mode

Quick and Simple Setup 

EZ mode displays vital settings and stats and also offers guided wizards, drag-and-drop functionality, and one-click application of important settings — all to help you get your rig up and running in no time.

  • Intuitive Graphical Fan Control - Fine-tune individual fan settings simply by dragging a curve with the mouse.
  • EZ XMP - Improve DRAM performance with one click.

Cooler by Design

Prime B550M-K is engineered with an array of hybrid fan headers and features comprehensive cooling controls that are configurable via Fan Xpert 2+ software or via the UEFI BIOS, ensuring your rig stays cool and stable under intense workloads. 

Multiple Temperature Sources

Each header can dynamically reference three thermal sensors. Fan Xpert 2+ allows you to map the temperature of supported ASUS graphics cards to optimize cooling for GPU- and CPU-intensive tasks.

Smart Protection

A dedicated integrated circuit protects each fan header from overheating and overcurrent. 

4-Pin PWM/DC Fan

Each onboard chassis fan header supports PWM and DC mode.

Build on a Solid Foundation

Prime B550 motherboard provides all the fundamentals to boost daily productivity, so your system will be ready for action with stable power, intuitive cooling and flexible transfer options.

Overvoltage Protection

World-class circuit-protecting power design

An exclusive circuit design with built-in voltage regulators to protect your motherboard from damage caused by unexpected high-level voltages from unstable or inferior power supplies.

DRAM Overcurrent Protection

Short-circuit damage prevention

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

3X corrosion-resistance for greater durability

Corrosion-resistant stainless-steel back I/O panels bonded with chromium oxide have a lifespan that's three times longer than ordinary panels.

LANGuard

Pumped-up throughput 2.5X higher surge tolerance

ASUS LANGuard is a hardware-level network protection feature that integrates advanced signal-coupling technology and premium anti-EMI surface-mounted capacitors to improve throughput and ensure a more reliable connection.

1000+

Low cost, efficient motherboard.

Product arrived in excellent condition. All the parts fit perfectly onto the board. The only problem I had was attaching the I/O shield onto the case and was missing one of the clips that secures it onto the case itself. Although the board was pushing against it anyway once screwed into the case so the I/O shield was secure enough. Would highly recommend for a low budget build.

Four sockets for ram let me use four sticks of 4gb for a huge cost saving. Two sockets for nvme gives high speed ssd with room to upgrade later or striping for speed. The ccl system building filter made it much easier to pick a great processor. I picked a ryzen 5 4600g with 6 cores so that no graphic card was needed.
