Hello! First-time poster. I searched around a bit and only found info around a year old. Curious if anyone can help with my situation:

Does anyone know of a motherboard which is Mini-ITX form factor, AM4 socket, and supports PCI-E Bifurcation?

I believe I need 4x4x4x4 Bifurcation to support this card presenting all 4 drives to the OS: https://www.asus.com/ca-en/Motherboard-Accessories/HYPER-M-2-X16-CARD-V2/

I could potentially also use Micro ATX, haven't looked into it much yet, but need a case under 13"x13"x15" or 330mm x 330mm x 380mm. The smaller the better, for more airflow, this is going onto a Kallax shelf https://www.ikea.com/ca/en/p/kallax-shelf-unit-black-brown-10275862/.

Also, is there any reason this would not work with an AMD Ryzen7 3700X?

Thanks!

Hi Weaseal.

I'm just finishing a build with Ryzen 3700X, Asrock X570 Phantom Gaming ITX, and x8x8 Bifurcation. Took a little playing with BIOS settings but it's working well now. It does not support x4x4x4x4 and the motherboard chipset heatsinks and right angle SATA connectors made it a slightly tricky build.

I agree, it looks like that card requires motherboard bifurcation support. Hope the build works out for you!
