Cables are used to connect devices. There are various types of cables that we sell and each cable performs a different function. These available cable types are Power Cables, Data cables, Interface Cables, Adapter Cables or I/O Cables. You will find the cable type listed in the Technical Specifications section of the page. It is important to note that the available cables can either be external or internal. Internal cables are cables that are housed within the computer chassis. These cables connect internal devices and mostly apply to desktops or servers. It is important to know the length of these cables or the form factor they are compatible with. External cables are external to a system and can apply to all computer types. Examples of external cable are power cords and connectors for projectors. All the important attributes of cables are listed in the Technical Specifications section of this page. To ensure compatibility of a cable with your system, we recommend that you use the System Drill Down or the Service Tag look up feature in the Parts For Your Dell tool. These features allow us to establish the system type, form factor, and connection type compatibility of the cable.
