Internal USB-C Upgrade

This adapter converts a motherboard or graphics-card 9-pin USB header into a standard USB-C port using a 50 cm 26AWG shielded cable. It targets builders adding front-panel USB-C connectivity or routing internal Type-C devices such as lighting controllers and card readers. Two cables are included for dual-header installations.

Shielded Build and Pin-Out

Tinned-copper conductors and double shielding reduce signal attenuation across the 1.6 ft length. The DuPont 4-pin female connector follows a fixed red V+, white D-, green D+, black GND sequence from the red end, so incorrect insertion is avoided by checking orientation before power-up. Plug-and-play operation requires no drivers or BIOS changes.

Header-Bound Bandwidth

The link is limited by the host header’s USB specification; no faster signalling is added by the adapter itself. Length and wire gauge cap practical throughput to whatever the motherboard or graphics-card header already delivers. Buyers needing higher internal bandwidth or additional independent ports must address those constraints at the header level.

Questions about this item

What USB standard does the 9-pin header on this cable support?

The cable connects a motherboard USB 9-pin header to a USB Type-C port using 26AWG shielded wire with tinned copper conductors for stable data transmission.

What clearance and pin layout does the DuPont connector need?

The DuPont 4-pin female connector follows a red V+, white D-, green D+, black GND pin order starting from the red end and requires a standard 9-pin header on the motherboard or graphics card.

How do I install the cable without reversing the DuPont pins?

Align the red wire to the V+ pin on the 9-pin header, then plug the USB Type-C end into the device; the 50 cm length gives enough slack to route inside the chassis.
