Vszerda Molex 4pin Power Extension Cable 14 Inches

This 14-inch extension cable adds reach to a standard Molex 4-pin LP4 power lead inside a desktop PC. It uses 18AWG copper conductors to carry 12V and 5V lines to hard drives, optical drives or other peripherals. The female-to-male connectors plug directly into an existing PSU cable and the device power socket. It suits builders who need extra length for routing behind motherboard trays or into larger cases.

Upgrade from short stock leads and tight routing

Replace a too-short factory cable when a drive bay sits farther from the power supply than the original harness allows. The 14-inch extension bridges that gap without splicing or crimping new connectors. The jump is worth it whenever cable tension risks pulling a connector loose or prevents a clean side-panel fit. It does not add new power rails, so systems needing additional Molex sockets require a splitter or a PSU with more native outputs.

Simple push-on fit with polarity keying

Installation takes seconds: align the keyed female end with the PSU cable and press until the latch clicks, then connect the male end to the drive. The polarised housing prevents reverse insertion, so wiring errors are unlikely if the connectors seat fully. The main failure mode is a loose latch that lets vibration unseat the plug, causing intermittent power to the drive. Routing the cable away from sharp chassis edges protects the 18AWG insulation from abrasion over time.

Questions about this item

What clearance is needed for the 14-inch Molex 4-pin extension cable?

The cable adds 14 inches of reach between the PSU and the drive, so allow at least that much free space along the routing path.

Which way round do the Molex 4-pin female and male connectors go during installation?

Plug the female end onto the existing PSU Molex lead first, then connect the male end to the drive; reversing them leaves the drive unpowered.

When should the 18AWG copper extension cable be replaced?

Replace it if the insulation cracks, pins become loose, or voltage drop causes drive instability.
