Prime B550M-A (Wi-Fi)
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.
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 features comprehensive cooling controls that are configurable via Fan Xpert 2+ software or via the UEFI BIOS.

● 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 optimise cooling for GPU- and CPU-intensive tasks.
● 4-Pin PWM/DC Fan: Each onboard chassis fan header supports PWM and DC mode.

PCIe 4.0 M.2(up to 64 Gbps)
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 PCIe 4.0 storage device to enjoy the fastest data-transfer speeds on the 3rd Generation AMD Ryzen platform.
Intel® WiFi 6 AX200
The Intel® WiFi 6 AX200 module is compatible with the 802.11ax standard and pushes theoretical peak bandwidth up to an incredible 2.4 Gbps. Perhaps more importantly for power users, it's optimised for more efficient operation on crowded networks with a lot of competing traffic. Pair your motherboard with ASUS WiFi 6 routers to fully experience the networking potential of WiFi 6.
* Actual speed varies, and depends on networking conditions.
USB 3.2 Gen 2 Type-A
Numerous USB ports support high-end rigs loaded with peripherals, including two rear-panel USB Type-A connectors with fast USB 3.2 Gen 2 connectivity for compatible cases.
Addressable Gen 2 RGB Header
The addressable Gen 2 RGB 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.
