PCI-E 4.0 X16 Riser Cable PCI Express Double Reverse GPU Extender Silver Cord for ITX A4 PC Case RTX4090 RX6800xt Graphics Card

Brand: ADT-Link 
Model: K33JK-SI

Product Name: PCI-E 4.0 x16 male to x16 female extension cable
Cable length:10-30cm length, the length can be customized , pls contact us for quotation.

Application: PCIe x16 graphics video card to PCIe x16 slot extension riser cable
Suitable graphics card: RTX4090 RX6800xt, supports PCIE4.0 graphics card
Compatible chassis: A4 ITX custom chassis, please contact the seller to purchase the according cable model and length

Usage restrictions:

1. Only the ITX motherboard and its accompanying mini chassis can be installed and used.

2. Graphics cards or motherboards older than four years are not supported.

3. PCIe4.0 has high requirements for equipment. As long as the extension cable is connected, the signal will be attenuated. This product does not guarantee the full speed of PCIe4.0. If the equipment is aging, the signal is poor or the environment is not good, please use it at a reduced speed.

Description of wire length and hole distance:
The length in the options refers to the length of wire, excluding PCB and connector's length. The length of the wire should refer to the size of the red arrow in the figure below. The spacing between screw holes is marked with the dimensions of the green arrow

Summary of technical issues
 
1)What is the quality of the wire? Is there a shield?
With metal layer shielding, the use of advanced EMI shielding conductive polymer, new materials for EMI shielding, flat cable design. This technique allows each cable to be fully covered by an EMI shield of conducting polymers to prevent incoming or outgoing electromagnetic frequency emission, minimize interference and performance degradation, and reduce the weight of the wire.

2) Is the wire soft? Is it bendable?
The wire can be bent and folded without affecting the use. Wire pulling torsion is prohibited

3)Why is the performance poor after connecting the extension cord? Or is it stuck or doesn't work?
Connected to the graphics card extension cable performance is insufficient or abnormal, there are three common problems:
1. The extension cable is incorrectly assembled. The graphics card extension cable should be installed in the graphics card slot nearest the CPU
2. The gold finger or motherboard slot terminal of the graphics card is not in good contact or oxide, resulting in slow stuck, gold finger contact point should be clean
3. Motherboard aging, aging graphics card, equipment more than 3 years do not recommend the use of extension cable. Equipment aging or signal is poor, please slow down the use

4)The difference between the industrial version and the foreign trade version?
And the difference between standard materials and materials to meet international standards and international certification
Industrial version of hard gold plating 20u plug resistance and long-term use can still maintain product stability in line with IPC industrial standards, according to IPC standard PCB plate material needs to be green
Foreign trade version for foreign sales requirements, UL/ROHS/CE/FCC certification, suitable for foreign trade sales unimpeded

5) Model K33QK with chip and K33JK no chip difference?
K series products all use PCIE5.0 cable wire, but considering that the signal attenuation may still fail to meet the requirements of PCIe 5.0 after the extension cable is added, model K33QK products have chips. Using Taiwan PHISON's PS7101 PCIe 5.0 Redriver Signal Repeater IC, this chip adjusts and compensates to regenerate signals to avoid signal failure caused by excessive cable loss
