    Hi,


    Question 1,

    A PCIe x8 card will physically fit into a PCIe x16 slot, and it will work as expected.

    The extra lanes on the PCIe x16 slot won't cause any issues.

    The card will only use the available 8 lanes and operate at the x8 speed.


    Question 2,

    Please follow the manual in DE5at-net by connecting the 6-pin PCIe external power connector to avoid damage to the board.


    Let me know if further clarification is needed.


    Regards,
