SKU CH-34QN-SVWA2

Adds two internal USB 3.0 Type-A ports from a single 20-pin motherboard header with 1.64FT cable and screw-mount brackets

  • Connection typeLighting Connector to USB A
  • Add two internal USB 3.0 ports via a single 20-pin motherboard header
  • 5Gbps data transfer speed for fast internal device connectivity
  • 64FT cable length reduces strain on the motherboard header
  • Mounting holes and screws included for secure PC case installation
  • Cleaner internal build by connecting devices directly to the motherboard

Internal USB 3.0 expansion

This adapter converts a single 20-pin motherboard header into two USB 3.0 Type-A female ports for internal devices such as card readers or hard drives. The 1.64FT cable length reduces strain on the header for a reliable connection. Female headers include mounting holes and screws for secure PC case installation. It is suited for builders adding front-panel or internal USB 3.0 ports.

Sustained data throughput

The cable complies with USB 3.0 specifications and supports data transfer speeds up to 5Gbps across both downstream ports. Performance remains consistent during extended file transfers because the direct header connection avoids external cable runs. Both ports share the single 20-pin upstream bandwidth, so simultaneous heavy use on both devices divides the available throughput.

Thermals and power draw

The passive adapter draws power directly from the motherboard header and adds no active cooling or noise. Power delivery follows the USB 3.0 specification limits of the host header. No additional power connectors or external supply are required for operation.

Questions about this item

Does the 1.64FT cable length help keep the 20-pin header cool during all-day use?

The 1.64FT length reduces strain on the motherboard 20-pin header, supporting a reliable connection during continuous operation.

Must my motherboard already have a 20-pin USB 3.0 header for this adapter to work?

Yes, the adapter plugs into an existing motherboard 20-pin USB 3.0 header to provide two Type A female ports.

Will my older USB 2.0 internal devices work with the two USB 3.0 Type A ports on this cable?

The USB 3.0 Type A female ports are backward compatible, so USB 2.0 internal devices will function when connected.
