Question

Iron

The Supermicro H11DSi motherboard claims to support pci-e 3.0 and not a word about pci-e 3.1, in turn, in the description of the Intel SSDPEDKX040T701 hard drive, the pci-e 3.1 type is declared, will the disk work on the board?

Answer 1

Here the PCI-E 6.0 specifications are backward compatible with all previous PCI-E including 1.0, and you are talking about 3.0 vs 3.1...
Yes, it should work.
