Power from USB to Molex

This Vszerda 2464 cable converts a standard USB 5V port into a 12V 4-pin Molex output using an internal step-up circuit. Each cable delivers up to 0.4A at 12V for a maximum of 11W, letting you run PC fans or fan hubs directly from a motherboard header or laptop port. The 30cm length suits internal chassis routing.

Build integration and constraints

The male-to-male PVC-insulated cable uses 22AWG tin-plated copper conductors with a 3.5mm outer diameter for flexible installation. It requires only a free USB-A port and a 4-pin Molex device, drawing 5V input to generate the 12V rail without an external power supply. No software or drivers are needed for operation.

Bundled value and usage

The pack includes two identical 30cm adapters, doubling the number of fans or hubs you can power from available USB ports. This enables dual-fan configurations for case airflow or DIY laptop cooling-pad modifications without occupying motherboard fan headers. The plug-and-play design means immediate function upon connection.

Questions about this item

What is the maximum power the step-up circuit can deliver before it limits output?

The built-in boost circuit is rated for a maximum of 11 W, which corresponds to 12 V at 0.4 A.

How much heat or noise does the cable generate when running a fan continuously?

The cable itself is passive PVC-insulated wiring with a small boost module; it produces no audible noise and only minimal warmth at the 11 W limit.

Which USB port standard must the host provide to supply the required 5 V input?

Any standard USB-A port delivering 5 V can power the adapter; no special protocol or higher-voltage port is needed.
