ASUS TUF GAMING B850M-PLUS mATX Motherboard | AM5 | 4x DDR5 Slots
Description
The ASUS TUF GAMING B850M-PLUS brings AMD's latest B850 chipset to a compact mATX form factor, making it an excellent choice for space-conscious builds that still need modern features. This AM5 socket motherboard supports the full range of current AMD Ryzen processors, including the latest 9000 series, 8000 series, and 7000 series CPUs. Despite its smaller size, it delivers the connectivity and expansion options that matter for gaming and productivity builds.
Memory support is particularly strong, with four DDR5 DIMM slots capable of handling up to 192GB of RAM. The board supports DDR5 speeds up to 8000+ MT/s when overclocked, and crucially includes support for both ECC and non-ECC memory modules. Storage connectivity covers three M.2 slots with varying PCIe generations - one PCIe 5.0 slot for the fastest NVMe drives, plus two PCIe 4.0 slots for additional storage. For graphics cards, you get one PCIe 5.0 x16 slot and one PCIe 4.0 x16 slot, along with a single PCIe 4.0 x1 expansion slot.
The board comes ready to install with mounting screws included, and the TUF Gaming series typically provides solid build quality and reliability. The B850 chipset represents AMD's mainstream offering, sitting between budget A-series boards and premium X-series models, giving you modern features without paying for extreme overclocking capabilities you might not need. All M.2 slots accommodate the standard 2280 form factor, making drive compatibility straightforward.
