Can you tell me if I can use a PCIe Gen3 x4 SSD disk (Intel SSDPEDMW400G4R5) in a 8 years old motherboard with a PCIe x8 (Supermicro PDSMA+) slot? There will be any speed caps? Like a SATA III disk on SATA II slot?

1PCIe is backwards compatible. A faster device will run at the slower speeds. So a PCIe x8 device will run at PCIe x4 speeds if plugged into a PCie x4 slot.– RamhoundSep 28, 2015 at 12:38

Thanks a lot @Ramhound! So it will fit but with a speed cap. Answer it so i can accept it...– Alex BogiasSep 28, 2015 at 12:40

As @Ramhound noticed the SSD will be compatible with the slot but it will have a speed decrease
