Prime B550-PLUS 3rd Generation Ryzen ATX Motherboard from ASUS
Newest Addition to the Prime Series Introducing the ASUS Prime B550-PLUS, expertly engineered to unleash the full potential of 3rd Generation AMD Ryzen processors. Ram-packed with features like the ground-breaking PCI-E 4.0 technology to give you lightning speeds, a robust power design, Type-C Rear IO connectivity, ASUS AURA RGB Header, 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.
Tweak and Tune Your Way
Wide Range of Performance and Tuning OptionsComprehensive 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 – maximising your productivity.
All-Around Energy efficiencyThe Energy Processing Unit (EPU) automatically optimises your power consumption and maximizes energy savings with a simple Away mode — a smart setting that creates an extreme energy-saving scenario by shutting down any unused I/O controllers.
Fan Xpert 4 Fan Xpert 4 software provides comprehensive control over fans, water pumps and all-in-one (AiO) coolers. Whether cooling with air or water, an Auto-Tuning mode intelligently configures all parameters with a single click. There's also an Extreme Quiet mode that reduces all fan speeds to below the default minimum to keep your system whisper-quiet when performing light tasks. Fans, water pumps and AiO coolers can also be controlled via the UEFI BIOS.
Precise Digital Power ControlThe Digi+ voltage-regulator module (VRM) gives real-time control over voltage drop, automatically switching frequency and power-efficiency settings. It also allows you to fine-tune your CPU for ultimate stability and performance.
World Renowned UEFI BIOS
Not just for veteransThe 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 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.
EZ(Easy) ModeEZ 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.
Cooler by Design
Cool to the corePrime B550 series features comprehensive cooling controls that are configurable via Fan Xpert 2+ software or via the UEFI BIOS.
Multiple temperature sources Each header can be set to monitor and react to several thermal sensors, and via Fan Xpert 2+ you can even assign a sensor to monitor the temperature of supported ASUS graphics cards — for optimal cooling during GPU- or CPU-intensive workloads.
4-pin PWM/DC Fan Every onboard header supports auto-detection of PWM or DC fans.
Smart Protection A dedicated integrated circuit protects each fan header from overheating and overcurrent.
Keep your Components Cool for Longer
Extended VRM Heatsinks and Thermal PadsTwo massive VRM heatsinks with underneath thermal pads improve heat transfer from the MOSFETs and chokes for better cooling performance.
Lightning Fast Storage with Dual M.2
Faster booting and app load times PCIe 4.0 M.2 Slot supports up to 22110 and provide NVMe SSD RAID support for an incredible performance boost. Create a RAID configuration with up to 64Gbps PCIe 4.0 storage device to enjoy the fastest data-transfer speeds on the 3rd Generation AMD Ryzen platform.
ASUS SafeSlot Protection
PREMIUM ASUS TECHNOLOGY SafeSlot is the PCIe slot reinvented by ASUS and engineered to provide superior retention and shearing resistance. Manufactured in a single step using 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.
Strengthened Solder PointsStrengthened solder points around the PCIe and DIMM pins.
Connections at your Fingertips
Little Things Make a Big Difference
Trustworthy Stability and Compatibility Prime B550 series adds the nuanced details that improve every experience, from exclusive codecs that provide pristine audio quality to intuitive RGB lighting controls that let you customize your system to create a uniquely personal look.
Overvoltage protectionAn 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 ProtectionOn-board 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/OCorrosion-resistant stainless-steel back I/O panels bonded with chromium oxide have a lifespan that's three times longer than ordinary panels.
LANGuardASUS 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.
