Technical FAQ:
Does the ADT K47SF-BK support PCIe 5.0?
Laboratory testing confirms full PCIe 5.0 speed capability.
Our store's test data is as follows:

What is the cable quality like? Is it shielded?
It features metal layer shielding using advanced EMI shielding conductive polymer—a new material for EMI shielding—with a flat cable design. This technology allows each cable to be fully covered by the conductive polymer's electromagnetic interference shielding, preventing incident or emitted electromagnetic frequencies, minimizing interference and performance degradation, and reducing cable weight.


Is the cable flexible? Can it be bent?
The cable is ADT's proprietary fifth-generation PCIe-specific black slim cable, 0.8mm thick. It is highly flexible and bendable without affecting functionality.


Is the PCB too long? Can it be shortened?
The PCB can be cut along the white line indicated by the arrow, maintaining structural compatibility.
