Power Delivery

This USB to fan adapter cable converts a standard 5V USB Type A port into a 12V output capable of delivering 0.4A. It enables full-speed operation of 3-pin or 4-pin PWM case fans directly from USB power sources.

Cable Specifications

Each cable measures 30cm in length and uses 22AWG pure copper conductors with PVC insulation rated to 80 centigrade. The braided sleeve and injection-moulded connectors protect the cores and reduce wire visibility inside a build.

Included Accessories

The pack contains two identical step-up cables, allowing two fans or a fan plus a hub to be powered simultaneously. No software or drivers are required for plug-and-play operation.

Questions about this item

What does the 12V 0.4A step-up rating mean when the cable is plugged into a standard USB port?

The built-in boost circuit converts the 5V USB supply to 12V at up to 0.4A, letting a 3-pin or 4-pin PWM fan run at full speed without a motherboard header.

How does the USB Type-A interface limit the power available to the fan?

A standard USB-A port supplies 5V; the cable's internal circuit steps this to 12V but caps output at 0.4A, so fans drawing more current will not reach full RPM.

Will the 30cm length and 22AWG conductors fit cleanly inside a typical PC case?

At 30cm the sleeved cable reaches most fan mounts without slack, and the 22AWG pure-copper cores handle the 0.4A load while the PVC insulation is rated to 80°C.
