Compact AM4 Platform

The ASUS TUF Gaming B450M-PRO S is a Micro ATX motherboard built on the AMD B450 chipset with a Socket AM4 interface. It supports DDR4 memory up to a maximum of 128GB for multitasking headroom. The form factor fits smaller chassis while retaining core connectivity.

Builder Fit

This board suits system assemblers who want a Socket AM4 foundation in a Micro ATX layout with 128GB DDR4 capacity. It is not intended for users who require a full-size ATX board or a different chipset feature set. Buyers needing a newer socket generation or alternative form factor should look elsewhere.

Deciding Spec

The single specification that determines compatibility is the Socket AM4 CPU interface paired with the AMD B450 chipset. Only processors designed for Socket AM4 will install and operate on this motherboard. Verify your CPU matches this socket before purchase.
