The length of the product refers to the length of the cable and does not include the PCB and connectors.
Technical questions in a nutshell
What is the quality of the wire? Is it shielded?
Yes, there is metal layer shielding with advanced EMI shielding conductive polymers, new materials for EMI shielding and flat cable design. This technology allows each cable to be completely covered by an EMI shield of conductive polymer to prevent incoming or outgoing emissions of electromagnetic frequencies, to miniaturise interference and performance degradation and to reduce the weight of the rows of cables.
Is the wire soft? Is it bendable?
Yes, the cable is a PCIe cable, the black version is 1.3 mm thick, the silver version is 1.4 mm thick and the blue version is 0.85 mm thick, the cable can be bent or folded and does not affect the use.
Why is the performance of the extension cable poorer when connected? Or is it slow or unusable?
There are three common problems with inadequate performance or abnormal functionality after connecting a graphics card extension cable.
1. The extension cable is incorrectly assembled, the graphics extension cable should be installed in the graphics slot closest to the CPU, the other slots have poor performance.
2. graphics card gold fingers or motherboard slot terminal contact is not good or have oxide, resulting in a slow card lag, gold finger contact points should be clean.
3. motherboard aging, aging graphics card, equipment more than 3 years is not recommended to use this extension cable. Equipment aging or signal is poor please reduce the speed of use.
