In the Amazon product reviews, few people wrote that it doesn't work.
I don't expect this to work in all motherboards because it will be drawing the whole power for the GPUs through a single PCIe slot, there is something similar to this on amazon too that has power cable on it, that should work instead of this, remember, the reason why riser works better is because you have to power it using molex or other
i confirm this works with gigabyte h110-d3a other mobo i did not test. i just bought and plugged there while ago
