I've found that you can run the GPU and have it also use the 12V from the PCIe slot, but because a GPU in general is configured for a 75W PCIe slot I went with the solution to completely cut the 12V supply from the PCIe slot.Some GPUs use the PCIe slot for power, the new ASUS GTX950 takes 75W from the slot, so that would be an example of a card that might not work with a PCIe 4x slot on a Thin-ITX board because the standard says, only a 16x slot may provide 75W of power.My solution and the reason I had chosen it is to make sure any GPU that is within the power budget and size constraint can be used regardless of the power it needs/wants from the PCIe slot.edit:Also that Powered riser you linked should work just fine, it is basically the exact solution I had used, only I had made a single PCB powered riser not a flexible powered riser
