Internal 19/20-pin header cable with USB-C and USB-A rear ports, 50cm

LORDWORLD

LORDWORLD USB 3.0 19/20-Pin to USB-C & USB-A 50cm

SKU CH-MD11-7SEE2

Adds a rear-panel USB-C and USB-A port pair running at 5 Gbps from a motherboard 19/20-pin header

  • Adds rear USB-C and USB-A ports from a motherboard 19/20-pin header
  • 5 Gbps data speed for SSDs and hard drives via both connectors
  • Backward compatible with USB 2.0 at 480 Mbps and USB 1.1 at 1.5 Mbps
  • 50 cm cable reaches most chassis layouts without strain
  • Type-C port is data-only — no video, docking or power delivery

19/20-Pin to USB-C & USB-A Adapter

This adapter converts a motherboard 19 or 20-pin internal header into one external USB Type-C port and one USB Type-A port on a PCI bracket. It operates at USB 3.0 Super-Speed 5Gbps and remains backward compatible with USB 2.0 and USB 1.1 devices. Builders adding front-panel or rear I/O connectivity to a desktop system will find it fits a standard expansion slot.

Suited for desktop builders needing extra USB ports

Ideal for integrators who want to expose a 19/20-pin header as both Type-C and Type-A sockets without occupying a drive bay. The Type-C connector carries data only; it does not deliver Power Delivery, carry DisplayPort Alt Mode video, or support audio and docking functions. Buyers who require charging, video output or dock connectivity through the Type-C port should look elsewhere.

5Gbps data rate over USB 3.0

The link runs at USB 3.0 Super-Speed 5Gbps, with fallback to 480Mbps and 1.5Mbps for older peripherals. This single throughput figure determines whether external SSDs, hard drives or other storage devices can reach their rated transfer performance when connected through either port.

Highlights

  • Backward compatible with USB 2.0 at 480 Mbps and USB 1.1 at 1.5 Mbps
  • 50 cm cable reaches most chassis layouts without strain

Questions about this item

Does the 50 cm cable add noticeable heat or power draw when the USB 3.0 ports run all day?

The adapter is a passive cable assembly; it draws no extra power beyond what the motherboard header already provides and generates no measurable heat of its own.

What motherboard header must my board already have for this adapter to work?

Your motherboard needs a standard 19-pin or 20-pin internal USB 3.0 header to plug the cable into.

Will the Type-C port work with my older USB 2.0 flash drives and external hard disks?

Yes, the port is backward compatible with USB 2.0 at 480 Mbps and USB 1.1 at 1.5 Mbps, so legacy devices function normally.
