Enfain 20-pin to dual USB 3.0 male adapter cable

SKU CH-B3ZH-C6CDC

Connects a motherboard 20-pin header to two USB 3.0 male plugs for front-panel expansion using 9-core shielded cable

  • Converts rear USB 3.0 to front 20-pin header for chassis expansion
  • 19-pin male to dual USB 3.0 male connectors enable front-panel connectivity
  • 9-core tinned copper wire with double shielding ensures stable data transmission
  • Optimised cable length prevents high-frequency signal rebound and minimises loss
  • 100% electrical testing and environmentally compliant materials guarantee reliability

Motherboard 20-pin to dual USB 3.0 adapter

This cable converts a rear USB 3.0 Type-A port into a standard 20-pin header for a front-panel USB 3.0 expansion. It is built for PC builders who need to add front USB 3.0 connectivity when the motherboard lacks a native 20-pin header. The adapter bridges the rear I/O to the chassis front panel without requiring an additional controller card.

Signal integrity with double shielding

The cable uses USB Association standard 9-core tinned copper conductors wrapped in aluminum foil and braided shielding. This construction reduces signal loss and prevents high-frequency signal rebound during differential transmission. The wire length is optimised to maintain stable USB 3.0 data rates across the conversion.

Tested materials and environmental compliance

All raw materials meet environmental requirements and every unit undergoes 100 percent electrical testing before shipment. The package includes the conversion cable itself with a 19-pin male connector and dual USB 3.0 male plugs. No driver discs or configuration utilities are bundled with this hardware adapter.

Questions about this item

How do I plug the 20-pin end into the motherboard header without bending pins?

Align the keyed 20-pin connector with the motherboard's 20P header, press straight down until seated, then connect the two USB 3.0 male plugs to rear ports; the key prevents reverse insertion.

Will the aluminum-foil-and-braid shielding degrade over time?

The double shielding is built into the 9-core tinned copper cable and requires no maintenance; it remains effective for the cable's service life.

At what cable length does signal loss appear first during sustained transfers?

The supplier tested and set the wire length to minimise differential-signal loss and eliminate high-frequency rebound, so the designed length is the limit.
