Internal USB 3.0 header adapter

This 20-pin to dual Type A cable adds two internal USB 3.0 ports to a motherboard header. It is built for system builders who want to connect internal card readers or drives without routing cables outside the case. The 50 cm length reduces strain on the header for a reliable link.

Build integration and clearance

The adapter plugs into a single 20-pin USB 3.0 header and splits it into two female Type A connectors. Mounting holes and screws on the female headers allow secure installation in a PC case. This frees external ports and keeps internal wiring tidy inside the chassis.

Mounting hardware included

Supplied screws and pre-drilled holes on the USB headers let you fix the ports directly to the case. No extra brackets or adhesives are required. The hardware turns the cable into a permanent internal I/O panel for front-panel or drive-bay devices.

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.
