Genuine Dell OEM USB IO Ribbon Cable

This is a genuine Dell OEM ribbon cable designed for the XPS 15z N511Z laptop. It connects the USB IO circuit board to the mainboard. The part is a working pull that has been tested for functionality. It is intended for repair technicians or owners replacing a damaged cable.

Sustained reliability as a board interconnect

As a passive ribbon cable, its behaviour under sustained load is defined by signal integrity rather than thermal limits. It maintains consistent data and power transmission between the USB IO board and motherboard during continuous use. There are no active components to throttle or degrade over extended sessions. The tested pull condition confirms the conductors and connectors remain intact.

Exact model compatibility decides fit

The single specification that determines whether this is the correct part is compatibility with the Dell XPS 15z N511Z (L511z) chassis. It connects specifically to USB IO boards such as KTYJ8 or GRWM0. Builders working on other Dell models or different XPS generations cannot use this cable. Buyers who need a different connector pinout or length must source an alternative part.
