ASUS TUF Gaming B550M-PLUS AM4 Micro-ATX Motherboard

The ASUS TUF GAMING B550M-PLUS is a Micro ATX motherboard that pairs the AMD B550 chipset with an AM4 socket, ready for 3rd Gen Ryzen processors. It gives builders who prefer a compact case the same performance edge usually reserved for larger boards, making it ideal for a space-conscious gaming tower, a living-room PC, or a streamlined workstation.

Four DIMM slots accept up to 128 GB of DDR4 memory and support overclocking to 4400 MHz, so users can fine-tune speed for demanding titles or multitasking workloads. Two M.2 slots allow fast NVMe storage; the primary slot connects over PCIe 4.0 x4, unlocking full bandwidth on compatible CPUs, while four SATA III ports handle additional drives in RAID 0, 1, or 10.

For graphics and expansion, the board offers a full-length PCIe 4.0 x16 slot plus a secondary PCIe 3.0 x16 and a PCIe 3.0 x1 slot, letting gamers install a powerful GPU, capture card, or other add-on without crowding the layout. HDMI 2.1 and DisplayPort 1.2 provide 4K video output for builds that rely on Ryzen integrated graphics.

Day-to-day connectivity is covered by USB 3.2 Gen 2 Type-A and Type-C ports for fast external drives, along with a 2.5 Gb Ethernet jack that features surge protection to keep multiplayer sessions stable. The Realtek S1200A codec drives 7.1-channel audio, and onboard Aura Sync headers make it easy to coordinate lighting with other ASUS gear. A BIOS FlashBack button even lets you update firmware without a CPU, handy when prepping a board for a new processor straight out of the box.

Whether you are building a first-time gaming rig, refreshing an older system with a Ryzen upgrade, or assembling a compact office PC that still needs muscle, this board delivers balanced features, robust power handling, and the durability that defines the TUF series.
