AM4 socket for Ryzen 5000 and 3000 series

This ATX motherboard uses the AMD B550 chipset and an AM4 socket. It supports AMD Ryzen 5000 and 3000 series desktop processors plus 5000 and 4000 G-series APUs. Four DDR4 slots accept up to 128 GB of memory in dual-channel mode.

12+2 teamed power stages for sustained delivery

The board employs 12+2 teamed power stages with ProCool connectors, alloy chokes and durable capacitors. This design keeps voltage stable during extended multi-core workloads rather than only in short bursts. PCIe 4.0 x16 and a primary M.2 slot run at full speed from the CPU.

WiFi 6E and 2.5 Gb LAN with LANGuard

On-board WiFi 6E (802.11ax) and Intel 2.5 Gb Ethernet provide high-throughput networking. ASUS LANGuard protects the LAN port against surges. HDMI 2.1 and DisplayPort 1.2 outputs are available when using a processor with integrated graphics.

Highlights

  • Supports AMD Ryzen 5000 and 3000 series processors via AM4 socket

Questions about this item

How loud or hot does the 12+2 teamed power-stage VRM get when the board runs all day?

The 12+2 teamed power stages with ProCool connector, alloy chokes and durable capacitors are designed for sustained loads; actual noise and temperature depend on your CPU cooler, case airflow and ambient conditions.

Which components must I already own for this AM4 board to POST and boot?

You need a compatible AMD Ryzen 5000, 4000 G-Series or 3000 series processor, DDR4 memory modules, an ATX power supply with 24-pin and 8-pin EPS connectors, and a graphics card or a Ryzen G-Series APU for video output.

Will my existing PCIe 3.0 graphics card and SATA SSDs work at full speed in the PCIe 4.0 x16 slot and the six SATA 6Gb/s ports?

Yes — the PCIe 4.0 x16 slot is backward compatible with PCIe 3.0 cards, and all six SATA 6Gb/s ports run at the native SATA III rate for your current drives.
