ASUS PRIME B550-PLUS Motherboard - AMD B550 ATX

ASUS PRIME B550-PLUS Motherboard - AMD B550 ATX delivers a balanced blend of performance and expandability for AMD Ryzen 3000 Series builders seeking a reliable ATX platform.

This PRIME B550-PLUS supports Socket AM4 processors and is optimized for AMD Ryzen 3000 Series CPUs, offering stable power delivery and compatibility for a wide range of Ryzen options.

Memory capacity and flexibility are strong points, with four DIMM slots that accept DDR4-SDRAM up to 128 GB and support ECC and Non-ECC modules. Supported memory clock speeds range from 2133 MHz up to 4600 MHz (with overclocking), enabling high-frequency builds for gaming and content creation.

Storage options include two M.2 slots and six SATA III connectors, with RAID support for levels 0, 1, and 10 to secure or accelerate data as needed. The dual M.2 configuration makes the board suitable for fast NVMe boot drives alongside large-capacity SATA arrays.

Connectivity covers modern needs with multiple USB ports (two USB 2.0, four USB 3.2 Gen 1 Type-A, and two USB 3.2 Gen 2 Type-A), a single HDMI and DisplayPort for discrete or integrated GPU output compatibility, and a Gigabit Ethernet port driven by the Realtek RTL8111H controller. Note that onboard Wi‑Fi is not included.

Audio is delivered in 7.1 channels and the board supports 2‑Way CrossFireX for multi-GPU setups. The ATX form factor, black and silver styling, and UEFI AMI BIOS (256 Mbit) round out a feature set aimed at mainstream and enthusiast builders.

Typical use cases include a versatile gaming rig with high-speed storage and overclocked memory, a content-creation workstation leveraging large RAM capacity and RAID arrays, or a reliable home/office PC requiring Gigabit Ethernet and multiple peripheral connections.
