Some of these B450 motherboards have already been leaked, but here’s the full list.
ASROCK
ASRock has two B450 Fatal1ty Gaming motherboards, the K4 which is a standard ATX form factor and ITX/ac which is a Mini-ITX version. So far, no word on Taichi and other models. We have pictures of Pro4 series though.
ASUS
ASUS has seven B450 motherboards coming. The STRIX F appears to be the best B450 motherboard from ASUS right now. If you prefer Mini ITX version then STRIX I should be your choice. The Prime series are available in three variants, while TUF B450 motherboards come in two flavors.
GIGABYTE
Those boards have already been posted elsewhere, but the list was lacking WiFi variant of AORUS PRO. It’s worth noting that Gigabyte has changed the naming schema for AORUS motherboards (for instance not B450M AORUS, but B450 AORUS M).
MSI
Meanwhile, MSI is preparing nine B450 motherboards. The top-tier features Gaming Pro Carbon AC and three Gaming Plus motherboards in Standard ATX, Micro ATX and Mini ITX form factors. Additionally, we have Bazooka and Mortar for mid-range builds and. The list continues with Pro series, which are ultra-cheap models not designed for gaming.
