ASUS has just launched a whole new range of motherboards based on the AMD B550 chipset, bringing the potential of PCIe 4.0 to all mainstream builds. These AMD B550 motherboards are compatible with 3rd Gen AMD Ryzen CPUs and are available in a wide selection of variants across ASUS' sub-brands.
ROG Strix series
The top of the range would be the ROG Strix series, under which ASUS will be releasing the B550-E Gaming and B550-I Gaming models.
The former is a full-sized ATX with top tier features, including 14+2 power stage VRM, reinforced PCIe x16 SafeSlots, dual M.2 slots, ample USB 3.2 ports, and an Intel-powered 2.5G LAN port.
The latter is a mini-ITX board for small form-factor builds, without compromising on game-centric features. It features a single PCIe 4.0 x16 slot, 8+2 power stage VRM, and a smattering of USB 3.2 Gen 2 Type-C and Type-A ports.
And of course, both boards support Wi-Fi 6 and Bluetooth 5.1 - it's year 2020 after all.
TUF Gaming series
The TUF Gaming B550M-Plus (Wi-Fi) takes most of the B550-Plus' features and fits them into a smaller microATX footprint, including the same pairs of PCIe x16 and M.2 slots. The main difference is that one of the M.2 slots only accommodates standard 80mm devices instead of longer 110mm units; to compensate, the board comes at a more attractive price tag than its full-sized sibling.
The TUF Gaming B550M-Plus comes in 2 variants: with or without Wi-Fi and Bluetooth 5.1 - either way, users will still enjoy 2.5Gbps Ethernet connectivity.
ASUS Prime series
The ASUS Prime series B550 motherboards - the B550M-A (Wi-Fi) and B550M-K -are M-ATX motherboards designed to save space in cramped office or bedroom locations. For the Prime B550M-A, you can choose between options that come with or without Wi-Fi 6 and Bluetooth 5.1 support.
