Internal USB 3.0 header adapter

This 20-pin to dual USB 3.0 Type-A cable adds two internal female ports to a single motherboard header. It is intended for builders who want to connect internal card readers or hard drives without routing cables outside the case. The 10-inch length reduces strain on the header for a more reliable installation. The black cable suits standard internal aesthetics.

One header splits into two ports

The adapter converts one internal USB 3.0 20-pin female header into two downstream USB 3.0 Type-A female connectors. This specific split is the deciding factor: the motherboard must provide a single 20-pin USB 3.0 header to support both ports simultaneously. No additional headers or external power are required for the connection.

Sustained 5 Gbps transfer rate

The cable complies with USB 3.0 specifications and maintains a 5 Gbps data transfer speed under continuous load. Internal devices such as card readers or hard drives can operate at full interface bandwidth without throttling from the splitter. The short 25 cm run helps preserve signal integrity during prolonged read or write sessions.

FeaturesConnect 2 internal USB 3.0 devices (internal card reader, hard drive) directly to a motherboard header connection. The Internal USB 3.0 Adapter Cable extends a 20-pin motherboard USB 3.0 header connection and enables you to add 2 internal female USB 3.0 (Type A) ports. With the addition of the 2 internal USB 3.0 ports, you can connect your internal devices (internal card reader, hard drive, etc.) directly to your motherboard, which allows for a cleaner installation, avoiding the need to run your cables outside the system case to external USB 3.0 ports.

Questions about this item

What does the 5 Gbps speed rating mean when this cable is installed in a system?

It provides up to 5 Gbps per port, so each connected internal device such as a card reader or hard drive can transfer data at full USB 3.0 bandwidth.

Which USB standard does the 20-pin header and the two Type-A ports follow, and what does that limit in practice?

Both the header and the two downstream ports are USB 3.0 compliant, capping each port at 5 Gbps and preventing use of USB 3.1 or 3.2 features.

What motherboard header and case space are required to fit this 10-inch cable?

A USB 3.0 20-pin male header on the motherboard and enough internal clearance for two Type-A female ports plus 10 inches of cable routing.
