Features:
1, PCIE X16 full bandwidth 4. 0 , GEN*3 protocol, compatible with gen3\gen4(Specific circumstances are required to fully operate in GEN4 state).
2,Conditions of use: Motherboard BlO*S supports changing PCIE operating mode to X8X8.
2,Gold finger sinking process, increase gold thickness to 5U.
3,Adopt new generation GEN*4 connector with dust plug and snap.
4,With clock splitting IC.
5,With power on LED indicator.
6,With CPU4P auxiliary power supply port.
7, 2cm slot spacing. Supports PCIE extension cable adapter.
Instructions for use：
1.Have a motherboard with vifurcation, make sure the motherboard is in the support list of the product.
2. Enter the motherboard BIOS and set for the PCIE slots to X8X8 mode.
3. Make sure the adapter is installed into the slot that is set to X8X8, not another PCIE slot.
Warm Tips:
1. If the two graphics cards are not running, you can set the PCIE speed to GEN3 and try it.
2. the device does not consume power, the motherboard provides a maximum of 75W to the PCIE, 75W if distributed to the two GPUs will result in insufficient power at the PCIE end, so additional supplementation is required, no matter how much supplementation you provide, it will only get what is needed.

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.

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.

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.

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/sPas 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.

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

It works as described and extends a PCIE slot. I have 2 PCIE 4 to 1 plugged into it and it works great!
