The ASUS TUF GAMING B550M-PLUS is a microATX motherboard engineered for the AMD AM4 socket, providing support for 3rd Generation AMD Ryzen processors. Built on the B550 chipset, it enables PCI Express 4.0 connectivity for the primary graphics card slot, allowing for maximum bandwidth with compatible components. The board's power delivery system utilizes an 8-pin EPS connector to ensure stable current for the CPU. Its compact form factor is suitable for smaller PC builds without sacrificing core performance features or connectivity.
This motherboard accommodates up to 128 GB of dual-channel DDR4 memory across its four DIMM slots, with support for speeds up to 4400 MHz. For data storage, it is equipped with two M.2 slots for NVMe SSDs and four SATA III ports, with RAID 0, 1, and 10 configurations available. Network connectivity is handled by an integrated 2.5GbE LAN port. The rear I/O panel provides a selection of USB ports, including USB 3.2 Gen 2 Type-A and Type-C, alongside both HDMI and DisplayPort outputs for use with processors that have integrated graphics.
