PRIME
The ASUS Prime series is expertly engineered to unleash the full potential of AMD Ryzen 5000 Series/ 5000 G-Series/ 4000 G-Series/ 3000 Series processors. Boasting a robust power design, comprehensive cooling solutions, and intelligent tuning options, Prime B550 series motherboards provide everyday 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 an underlying 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 be dynamically mapped to 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 Header
Each onboard chassis fan header supports PWM and DC mode.

PCIe 4.0 M.2 (up to 64 Gbps)
Speed up with onboard M.2

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 a PCIe 4.0 storage device to enjoy the fastest data transfer speeds on AMD Ryzen™ 5000 and 3000 Series processors.

Wi-Fi 6
The Wi-Fi 6 module is compatible with the 802.11ax standard and boosts theoretical peak bandwidth up to an incredible 2.4 Gbps. Perhaps more importantly for power users, it's optimized for more efficient operation in crowded networks with a lot of competing traffic. Pair your motherboard with ASUS WiFi 6 routers to fully experience the network potential of WiFi 6.

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.

Little Things Make a Big Difference
Outshine the Competition
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.
