Prime
ASUS Prime series motherboards are expertly engineered to unleash the full potential of the AMD Ryzen 5000 series. Boasting a robust power design, comprehensive cooling solution, 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.
Digi+ VRM 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.
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.
Flexible 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.
VRM Heatsink and Thermal Pads
A VRM heatsink with underneath thermal pad improves heat transfer from the MOSFETs and chokes for better cooling performance.
Cooler by Design
Prime B550 series motherboards feature comprehensive cooling controls that are configurable via Fan Xpert 2+ software or via the UEFI BIOS.
UEFI Bios
The 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 Tuning
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.
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.
Achieve Speed with Onboard M.2
PCIe 4.0 M.2 Slot supports up to 22110 and provides NVMe SSD RAID support for a strong performance boost. Create a RAID configuration with up to two PCIe 4.0 storage devices to enjoy the fastest data-transfer speeds on AMD Ryzen 5000 Series and 3000 Series Processors.
Combined Onboard Features Deliver Elevated Audio
Audio shielding separates analog and digital signal domains, significantly reducing multi-lateral interface, while a separate layer for left and right tracks ensures minimal crosstalk between audio paths. Additionally, premium audio capacitors provide an immersive sound signature, with exceptional fidelity.
SafeSlot Core
SafeSlot core is the ASUS-exclusive PCIe slot. Featuring a fortified design that's anchored to the motherboard by a special hook, SafeSlot Core provides 1.6x stronger retention and 1.3x greater shearing resistance than standard expansion slots.
Aura Sync
A well-tuned enthusiast system deserves a matching aesthetic. ASUS Aura offers full RGB lighting control with a variety of functional presets for RGB LED 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 Header
The addressable Gen 2 header is 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.
Armoury Crate
Armoury Crate is a software utility designed to give you centralized control of supported products. From a single intuitive interface, Armoury Crate allows you to easily customize RGB lighting and effects for every compatible device in your arsenal. The software also provides control of settings for ASUS products, including keyboard and mouse preferences. Armoury Crate even features dedicated product registration and highlights to help you stay in touch with the ASUS community.
