JMT PCI-E 4.0 x16 1 to 2 Expansion Card Gen3 Split Card PCIe-Bifurcation x16 to x8x8 with 20mm Spaced Slots CPU4P Power Supply Port (+4Pin Cable)

With the addition of a x16 riser, this works great with my Z490 Phantom Gaming-ITX/TB3 motherboard. My ITX case (Nanoxia Project S Mini) came without a riser and to make matters worse, the pcie slots are oriented backwards (card end connector away from motherboard). This bifurication card allowed me to securely mount a single slot Nvidia Quadro card and a four port Elgato capture card.Initially I used a riser cable from another brand as it was the only one I could find that would tolerate a complete 180 turn and still fit without unsafe bending. I had issues with the PC locking up using that setup. Switching to the "JMT PCIE 4.0 X16 Extension Cable...", although pricey, fixed the crashing issues. I definitely recommend keeping the whole chain JMT brand, even if its going to cost you a bit more.

Connector doesn't extend out enough to use with even just one GPU. You'd need THREE riser cables on top of this to even attempt to use it.

mine could not negotiate beyond gen 1, on one port. Other than that it seemed nicely built. However I returned it. Another style worked fine. I wanted this wider style but didn't try again. Bad luck?

It works well! Just make sure your motherboard supports it.

setup:MITX pcie4.0 bus to bifurcation X8X8 gen 4 for sff pc.Split for rtx4070super and sound blaster AE9.Plug and play on Asus and Asrock after bios setting.Works flawlessly from mother board bus to riser to this splitter. No divers issues.Recommended for this use.

Connected with a 16x riser cable to a mATX mobo capable of 8x/8x bifurcation. Fits in 2U case next to mobo and works a treat.I get my full 2x 8lane PCIe slots after all.

Configured motherboard for x8x8 bifurcation on the x16 slot.Plugged one GPU into expansion card to test.Seconds after powering on PC the card shorted and the PC shutdown.PC fails to post. Incredibly expensive mistake

Pcie 4 bifurcation works.Easy to install and use.
