Internal computer cabling:

Which cables are available?

Internal PC cables form the core network of a computer. In the following section, you will find the most common variants and their properties and areas of application.


InLine offers a wide range of connection and adaptation options for internal cabling. Below are some examples of products for a technically flawless and clearly organised power supply. Our entire range with a variety of other solutions, such as 20-pin to 24-pin power supply mainboard adapters and Wake-On-LAN cables, which start the computer from the network, and SCSI cables, and, and, and ...

SATA cables


SATA is a transmission standard for data exchange between mainboards and internal drives (CD, DVD, SSD, HDD, etc.). The three most common protocols differ primarily in terms of data throughput (1.5 Gbit/s, 3.0 Gbit/s and 6.0 Gbit/s). They are upwards and downwards compatible with each other, whereby the system operates at the speed of the slowest component.
InLine offers a wide range of high-quality SATA cables with application-specific features such as optional shielding, safety tabs, different lengths and various connectors. External devices can also be connected to the PC using special eSATA cables. They differ from the internal variants primarily in terms of the connectors.
