    It doesn’t give you an extra, unless you have an itx board as it just takes the 8 lanes from the second 16x slot and feeds 4x of them to the SSD.

      i thought it would work liek this
      without ssd on gpu
      slot 1: gpu (uses 8x lanes)
      slot 2: dual ssd bifurcation card (4x lanes per ssd)
      total 2 nvme ssd in 2 slots

      with ssd on gpu
      slot 1: gpu + ssd (4x lanes each)
      slot 2: dual ssd bifurcation card (4x lanes per ssd)
      total 3 nvme in 2 slots

      assuming that the gpu only needs 4x lanes of pcie 5.0

      you get an extra ssd in this scenario which would not be possible without a GPU that natively does PCIE 5.0 at 4x.

        Nope, if you use the second 16x slot the first only gets 8 lanes due to bifurcation, so no GPU SSD. If on the other hand we got 4x pcie5 GPUs this would make sense. Sadly there are no PCIe gen 5 GPUs yet, so they all use more gen 4 lanes.
