DELL XPS 730 USB Cable IO Master Panel to Motherboard RU493

Genuine Dell XPS 730 Master Panel Cable

This genuine Dell RU493 cable connects the front I/O master panel to the motherboard inside a Dell XPS 730 desktop. It restores the data path that enables the front USB ports to function correctly. The part is an OEM component built for that specific model, so fit and signalling are guaranteed without adapters. It is sold new in a lot of two cables.

Black Connector Built for Exact Routing

The black master-panel connector matches the original routing and keying inside the XPS 730 chassis, so installation follows the factory cable path. No extra brackets or soldering are required; the plug seats directly into the motherboard header and the panel PCB. Because the cable is model-specific, there is no risk of pin-out mismatch or loose retention clips. The second cable in the lot provides a spare for future service.

Replaces a Faulty or Missing Front USB Link

This cable replaces the original link when front USB ports stop responding due to a damaged or missing harness. The upgrade is worth it when diagnostics show the motherboard header is live but the panel remains dead, or when a chassis swap leaves the system without the correct internal cable. It does not add ports or change the USB standard supported by the board. Builders needing additional front-panel headers or a different connector type cannot use this part.
