## Description

JMT PCI-E 4.0 x16 1 to 2 Expansion Card Gen*3 Split Card PCIe-Bifurcation x16 to x8x8 with 20mm Spaced Slots CPU4P Power Supply Port 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.

Review: Works great in an ITX case with cramped quarters! - 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.
Review: Poor QA, PC only boots without it plugged in. Fails to work. - 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.

### ⭐ Poor QA, PC only boots without it plugged in. Fails to work.
*by A***J on January 17, 2026*

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.

### ⭐⭐⭐ mine could not negotiate beyond gen 1, on one port.
*by B***L on May 27, 2025*

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?
