I’m looking at quad port 2.5Gbe Intel PCIe cards. These cards seem to be mostly x4 physically (usually PCIe gen 3) whilst I have a PCIe Gen4 X1 slot, which is more the theoretical bandwidth that the card can support. The card needs at the most PCIE Gen 3 X2 == PCIE Gen 4 X1 in terms of bandwidth.

How do I fit the card into a PCIe x1 slot? Won’t it lose performance if all the pins are not connected to the physical PCIe connector? Is there a PCIe x1 riser that the community likes that is somewhat affordable?

Thanks

    I did this but buying these on Amazon is scary. Try to find one that won’t burn your house down.

      Yeah, I definitely wouldn’t recommend putting something power hungry like a GPU in one of these. A NIC will be fine though.

        The ones on Amazon are intended to run GPUs for crypto farms, but they’re all brands you’ve never heard of with dubious claims and they’ve all got at least one review where either the device was defective or something was installed incorrectly and it caused damages.
