4Pin Female to 5V USB Male Adapter Cable, USB to 4 Pin Molex Fan Power Connector Cord, Computer Case Chassis Cooling Fan Power Supply Conversion Adapter Wire

This 4Pin Female to USB Male power adapter cable is an ideal conversion accessory for DIY computer chassis modification. It can convert standard 5V USB power into power supply for equipment with 4Pin Molex interface. You can connect it to USB ports on PC, power bank, notebook and other devices to drive chassis cooling fans, decorative LED light strips and other low-power peripherals conveniently.

Built with premium conductive copper core, the cable guarantees stable 5V power delivery, effectively avoiding fan stalling, flickering and unstable operation caused by poor power connection. The flexible wear-resistant outer casing resists repeated bending and abrasion, adapting to limited installation space inside the computer case. Precision molded connectors maintain tight contact to prevent intermittent power failure.

Plug and play without extra drivers or complicated setup. Perfect for users who want to add silent cooling fans or ambient lighting without modifying the power supply. Great for desktop chassis decoration, small cooling equipment and portable low-power device power supply.
