Core Platform

The MSI B450 Tomahawk is an ATX motherboard built on the AMD B450 chipset with an AM4 socket. It provides one PCI Express 3.0 x16 slot and a single M.2 connector for expansion. Four DDR4 memory slots support up to 128GB of system memory.

System Builders

This board suits builders assembling a new AM4 system who need a full-size ATX layout and do not require bundled accessories. It is not for buyers who need an I/O shield, SATA cables or a manufacturer warranty in the box. It is also not for builds that require multiple PCIe x16 slots or onboard Wi-Fi.

Memory Capacity

The maximum supported memory is 128GB across four DDR4 slots. This figure determines whether the board can handle the planned workload or if a platform with higher capacity is required.
