PCI-E Bifurcation Adapters

[chuckthetekkie]

I have an ASRock Rack TRX40D8-2N2T motherboard and I need to take one of the X16 PCI-E slots and bifurcate it to two X8 slots but I am having a real hard time finding something that would do the job. I am using the Fractal Meshify 2 XL Case so it has 3 vertical slots which would work great for holding the 2 HBA PCI-E cards I want to use with the adapter.

 

Do any Bifurcation Adapters exist that would work for what I am trying to do?

a ebay/amazon/google search for "PCIe Bifurcation riser" finds many results in many configurations.

Are there any that are PCIe GEN 4?
