Document What is this?USB to 4-Pin PWM 5V fan power adapter cable is designed to power 3-pin/4-pin PC case fans with USB Type-A ports. It supports both 3-pin and 4-pin fan connectors, enabling direct power supply from USB sources to cooling fans.What will I get?You will receive a 2 pack of USB to 4 Pin-molex Port PWM 12 voltage step-up fan power adapter cables with Switch. Each cable features a USB-A connector on one end and a 4-pin PWM fan connector (3-pin/4-pin fans) on the other. The black PVC cable length: 30cm/11.8", Outer Diameter: 3.5mm, Output voltage: 12V.Is there any advantage of the product?This adapter transforms the 5V voltage supplied by the USB port into the 12V voltage used by the computer fan with a boost module, without affecting the fan's original speed or the brightness of the lights. Key advantages include PWM compatibility, 3-pin/4-pin connector support. The PVC design enhances durability, while the compact size ensures easy integration into PC builds or USB-powered devices.How to use it?Connect the USB-A end to a USB port, and the 4-pin connector to your fan. Ensure the fan’s starting voltage is rated voltage. For optimal cooling, pair with PWM-compatible fans and avoid overloading beyond rated power.What should I notice?Only use with fans rated voltage, verify fan compatibility with 3-pin/4-pin connectors. Avoid bending the cable excessively to prevent damage to the tinned copper wires. Test with a single fan before connecting multiple devices.
