Introduction

ABSOLUTE SIMPLICITY
B650M PROJECT ZERO moves the power connectors, fan connectors, and other pin headers to the back of the motherboard. This provides a cleaner and neater front view, allowing the motherboard, liquid cooler, and graphics card's aesthetic design to be fully displayed.

LIGHTNING GEN 4 PCI-E
MSI lightning Gen 4 PCI-E represents the bandwidth of a x16 interface to 64GB/s that has doubled compared to its previous generation.

REINFORCED,
HEAVY SOLDERED CONNECTIONS
MSI PCI Express Steel Armor slots are secured to the motherboard with extra solder points and support the weight of heavy graphics cards. When every advantage in games counts, Steel Armor shields the point of contact from electromagnetic interference.
