Power optimisations and enhanced on-chip capabilities have made AMD’s new AM4 platform a tempting proposition for users who prefer the size benefits of micro-ATX. MSI offers up the £90 B350M Mortar to cater for those users with a 4+2 phase power delivery system and onboard red LED lighting.
The B350M Mortar shares many similarities with comparably priced motherboards in MSI’s B350 Arsenal range. Overall styling is very similar to the ATX-sized B350 Tomahawk and the inclusion of four SATA 6Gbps ports, a single M.2 connector, and USB Type-C add to the list of similarities.
PCIe bifurcation is not supported on the B350 chipset so MSI is clearly tailoring the B350M Mortar to single-card micro-ATX users who want a cost-effective way of overclocking their Ryzen system.
With many of the core features boxes ticked, can the MSI B350M Mortar prove itself as a smart choice for an overclockable micro-ATX AM4 motherboard?
