## 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.

## Customer Reviews

### ⭐ Poor QA, PC only boots without it plugged in. Fails to work.
*by  on Reviewed in the United States 17 January 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.

### ⭐⭐⭐⭐⭐ Perfect. Does exactly what I need
*by  on Reviewed in the United States 4 January 2025*

Pcie 4 bifurcation works.Easy to install and use.

### ⭐ Doesn't work as intended
*by  on Reviewed in the United States 14 April 2026*

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