The MSI MAG B850 TOMAHAWK WIFI is the objective winner of this comparison, securing more individual specification victories than its competitor. While both boards share many identical features, the MSI MAG B850 TOMAHAWK WIFI holds a significant advantage in expansion capability, offering 100% more PCIe x1 slots than the ASRock B850 Steel Legend WiFi. This makes the MSI board the superior choice for users requiring additional connectivity for expansion cards and peripheral hardware.

Users who prioritize extensive expansion options should select the MSI MAG B850 TOMAHAWK WIFI for its superior PCIe slot count. Conversely, the ASRock B850 Steel Legend WiFi is the better option for builders who prioritize power delivery, as it features VRM phases that are 24% better than those found on the MSI alternative. Choosing between these two motherboards depends entirely on whether your specific build requires more expansion slots or enhanced power delivery components.
