You're planning to purchase the MSI B450M Mortar Max motherboard and want to confirm compatibility with your Nvidia GeForce GTX 1660Ti. It looks like it should work, but the PCI-E slots have fewer lanes than some other models, such as the Tomahawk. The numbers you mentioned suggest a lower capacity, which might be a concern if you need more expansion. Let me know if you'd like further details!
The values indicate the PCIe ports, lane count per port, and supported PCIe version. The combination of version and lanes mainly affects GPU performance, but in real scenarios the extra slots and their speeds often don’t change much—especially with common setups like the Mortar or Tomahawk using PCIe 3.0. This shouldn’t be an issue unless you intend to use those ports for storage or other purposes.
