Cable length Description:
The length of the wire refers to the part of the visible wire. It does not include the PCB and the connector. For the wire length, please refer to the blue arrow in the figure below.

Can the PCB be shortened?
Yes, the PCB on one end of the K49SA M.2 can be cut according to the white line indicated by the arrow, and the minimum supported size is 2230

Can K49SA-BK support PCIe 4.0?
The laboratory test shows that it can reach the full speed of PCIe4.0. The difference between the 3DMARK running score after the graphics card dock adapter and the direct plug-in running score is only 1%
The actual test data of our store is as follows:

Test equipment: 7600x + 4070 + Xingu 850W power supply (direct plug)

Test equipment: 7600x + K49SA + F9G + F9934 + 4070 + Xingu 850W power supply (using graphics card dock adapter)

How is the quality of the cable? Is it shielded?
It has a metal layer shield, uses advanced EMI shielding conductive polymer, a new type of material for EMI shielding, and a flat cable design. This technology allows each cable to be completely covered by the electromagnetic interference shielding of the conductive polymer to prevent the incident or outgoing emission of electromagnetic frequencies, minimize interference and performance degradation, and reduce the weight of the cable.

Is the cable soft? Can it be bent?
The cable is the fifth-generation PCIe dedicated cable independently developed by ADT
It is a thin black version with a thickness of 0.8mm. The cable is very soft and bendable, which does not affect its use.
