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 (with 4Pin Cable Higher)

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.

Does not split - passes all the data through to a single card.

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.

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.

Mine did not work. The PC would not boot with it plugged in. The SATA power port and PCI-E x16 Slots were very loose. I believe the soldering job was poor and losing contact. Wasted $45. I wouldn't recommend this product.

Pcie 4 bifurcation works. Easy to install and use.

Stated 4.0 but read on from the title. As i think the lister of the item is trying to hit search results. This is for Gen3 and as such it will ever not work, like in my situation, or you will have slower speeds.

J'ai une carte mATX pour construire mon DIY NAS. Je n'ai qu'un port PCIE x16 sur cette carte mère. - il y a un port X4 pour une carte intel 2 ports RJ45 10Gb/s - un port nvme transformé en port PCIE x4 pour une carte SFP+ 10Gb/s Pas besoin de carte graphique, donc j'aimerais utilisé ce port (16 lignes) pour autre chose. 1 carte HBA (4X4 ports SATA) pour les disques, c'est bien, mais c'est une carte x8 et n'est pas optimal pour du disque en miroir. 2 HBA seraient plus utiles, mais il faut 2 ports x8. Et ben voilà, cette carte est exactement fait pour ça : diviser x16 en x8 + x8. bien sûr, il faut activer la bifurcation dans le BIOS en fonction du résultat voulu : ici 2 fois x8. j'ai essayé le 4 fois X4, mais d'après mes lectures, certaine puces intel ne permettent que x8x4x4. Sur les photos, on voit (CPU watercoolé): - cable rizer pour brancher cette carte de bifurcation pcie - 2 carte HBA SAS sur cette carte de bifurcation - NAS boitier fermé à moins de 30° en vitesse de croisière.
