Hello,
I am going to buy a mainboard with pci-e slots v.2.0 and would like to use a videocard with pci-e v.2.1 with it. Will that work? Massimo |

The only source for incompatibility I know is that PCI Express 2.1 allows for up to 150 W power from a PCI-E slot, up from 75 W in 2.0. So, if you have the videocard in hand, its rated power is over 75 W and it has no extra power connector = not compatible with a PCI-E 2.0 motherboard. No idea if anyone has made such a videocard though. |

All PCI-e revisions are backwards compatible. PCI-e 2.1 is the same speed as PCI-e 2.0 but supports features planned for PCI-e 3.0. |

I already tried and saw that it functioned without smoke. ;-) Massimo |
