Product information

Description

The ASUS PRIME B550M-A WIFI II is a micro‑ATX motherboard based on the AMD B550 chipset with Socket AM4 support for AMD Ryzen 3000 and 5000 Series processors. It offers a balanced foundation for daily productivity and DIY PC builds, with robust power delivery, comprehensive cooling options, integrated Wi‑Fi 6, PCIe 4.0 M.2 support and multiple connectivity options including USB 3.2 Gen 2 and Gigabit Ethernet.

Advantages

The board provides flexible tuning via the ASUS UEFI BIOS and Fan Xpert 2+ software, allowing both beginners and advanced users to configure system settings, fan curves and memory performance (EZ XMP). Onboard features include PCIe 4.0 M.2 for high-speed NVMe storage, integrated Wi‑Fi 6 for faster wireless networking, reinforced SafeSlot Core for improved PCIe retention, and enhanced protection such as overvoltage and DRAM overcurrent protection. Audio and RGB control are handled through onboard codecs and Aura Sync with an Addressable Gen 2 header.

Suitable for

  • Home and office PCs that require a compact micro‑ATX motherboard
  • DIY builders seeking a platform for AMD Ryzen 3000/5000 processors
  • Systems needing M.2 NVMe storage with PCIe 4.0 performance
  • Users who want integrated Wi‑Fi 6 and multiple USB 3.2 Gen 2 ports

Key specifications

  • Form factor: Micro ATX
  • Chipset: AMD B550
  • CPU socket: Socket AM4 (supports Ryzen 3000 and 5000 Series)
  • Memory: 4 × DDR4 DIMM slots, up to 128 GB
  • Storage: PCIe 4.0 M.2 (supports up to 22110), SATA III
  • Expansion: 1 × PCIe x16 (Gen3), 2 × PCIe x1 (Gen3)
  • Networking: Wi‑Fi 6 (802.11ax) and Gigabit Ethernet (Realtek)
  • USB: Rear USB Type‑A ports including USB 3.2 Gen 2
  • Protection features: Overvoltage protection, DRAM overcurrent protection, stainless‑steel back I/O

How to use

Install the motherboard into a compatible micro‑ATX case, mount an AM4 CPU and cooler, populate DDR4 DIMMs across the four slots up to 128 GB, and connect storage devices to M.2 and SATA connectors as needed. Use the UEFI BIOS to configure boot order, enable EZ XMP for one‑click memory optimization, and access Advanced mode for manual tuning. Configure fan curves and thermal sensors with Fan Xpert 2+ or via UEFI, and enable or disable onboard RGB lighting with Aura On/Off mode.

Reasons to buy

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.

Precise Digital Power 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.
