Asus Prime B550M-A WIFI II Motherboard Micro ATX with AMD AM4 Socket

The Asus Prime B550M-A WiFi II motherboard is aimed at users who want a reliable and affordable solution for their computer, while offering high performance and flexibility.

The ASUS Prime series is expertly engineered to unleash the full potential of the 3rd generation AMD Ryzen platform. Featuring a robust power design, comprehensive cooling solutions, and intelligent tuning options, the Prime B550 series motherboards provide everyday users and DIY PC builders with a range of performance options through smart software and firmware features.

VRM Heatsink and Thermal Pads

A VRM heatsink with a thermal pad underneath improves heat transfer from the MOSFETs and chokes for better cooling performance.

System Cooling

The Prime B550 series features comprehensive cooling controls that can be configured via the Fan Xpert 2+ software or through the UEFI BIOS.

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.
A dedicated integrated circuit protects each fan header from overheating and overcurrent.
Each onboard chassis fan header supports both PWM and DC modes.

Storage

The PCIe 4.0 M.2 slot supports up to 22110 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 3rd generation AMD Ryzen platform.

Connectivity

Numerous USB ports support high-spec equipment loaded with peripherals, including 6 USB Type-A slots on the back with fast USB 3.2 Gen 2 connectivity for compatible cases.

Aura Sync

A well-tuned system deserves a corresponding aesthetic. ASUS Aura offers full control of RGB lighting with a variety of functional presets for RGB LED strips connected to the integrated RGB headers. And all of this can be synchronized with an ever-growing portfolio of Aura-capable hardware.

Armoury Crate

Armoury Crate is a new 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 over settings for ASUS products, including keyboard and mouse preferences. Armoury Crate even features dedicated product registration and highlighting to help you stay connected with the ASUS community.

SafeSlot Core

SafeSlot Core is ASUS’s exclusive PCIe slot. Featuring a reinforced design that anchors to the motherboard with a special hook, SafeSlot Core provides 1.6 times stronger retention and 1.3 times greater shearing resistance than standard expansion slots.
