AMD B550 Micro-ATX motherboard for Ryzen builders

The GIGABYTE GA-B550M PRO-P fits AMD AM4 processors including Ryzen 3000 and 5000 series CPUs. It delivers four DDR4 DIMM slots supporting up to 128 GB of system memory. A single PCI Express x16 slot connects directly to the CPU for graphics or high-speed add-in cards.

Sustained load behaviour

The onboard Realtek 2.5GbE network chip maintains 2.5 Gbit, 1 Gbit or 100 Mbit links without a discrete card. Realtek ALC1200 audio drives up to 7.1 channels and S/PDIF out for extended sessions. Chipset cooling is passive so airflow across the VRM area determines thermal headroom.

Straightforward AM4 install with minimal accessories

The board measures 24.4 cm square and mounts in any Micro-ATX compatible chassis using standard standoffs. Only one SATA cable and the rear I/O shield are included so builders must source additional cables and CPU cooler brackets. Verify AM4 cooler clearance against the VRM heatsink before ordering.

Perguntas sobre este artigo

How loud or hot does the board get when the 2.5 GbE LAN and Realtek ALC1200 audio run continuously?

The motherboard uses a passive chipset heatsink and the Realtek 2.5 GbE plus ALC1200 audio controllers draw little power, so noise and heat stay low during all‑day operation.

Which essential components are not in the box and must already be owned for the system to boot?

The package contains only the board, one SATA cable and the I/O shield; you must supply an AM4 Ryzen processor, DDR4 memory modules, storage drives and an ATX power supply.

Will my existing SATA III SSD and hard drive work at full speed on the four SATA III ports?

Yes, the four SATA III interfaces run at the standard 6 Gb/s rate, so any SATA III SSD or mechanical drive will operate at its rated throughput.
