Flat blue ribbon cable with 20-pin motherboard header plug and stacked dual USB-A ports with screw holes

Fervit USB 3.0 Motherboard 20-Pin Header to Dual USB-A Female Cable 50cm

SKU CH-9WQP-4EXXZ

Connects a motherboard 20-pin header to two USB 3.0 Type-A ports, delivering up to 5Gbps throughput with a 50cm flat cable

  • Ultra-flat 50cm cable saves space inside tight cases
  • Dual USB 3.0 Type-A ports from one 20-pin motherboard header
  • Up to 5Gbps throughput with USB 3.0 host and device
  • DIP connector with fixed feet secures PCB connection
  • Two screw holes on female end allow firm chassis mounting

Product Purpose

This cable converts a single motherboard 20-pin header into two USB 3.0 Type-A ports for front-panel or custom chassis use. It suits builders adding front-panel connectivity to cases that lack native USB 3.0 headers or extending ports to a drive bay bracket.

Speed Limit

Throughput reaches 5Gbps when both host controller and attached device support USB 3.0, otherwise the link falls back to USB 2.0 speeds. The flat ribbon design meets the USB 3.0 base specification but offers no active signal conditioning beyond the 50cm length.

Installation Notes

The DIP-style header with fixed feet plugs directly onto the 19-pin section of a 20-pin motherboard connector; align the keyed notch to avoid bent pins. Two screw holes on the female bracket secure the ports to a chassis cut-out, and the ultra-flat ribbon eases routing behind motherboard trays. Builders needing more than two ports or a longer reach must use a different solution.

Questions about this item

Should I choose the 20-pin or 19-pin header version for my motherboard?

The cable plugs into a standard 20-pin USB 3.0 header; the 19-pin reference in the title simply notes the keyed pin layout used by most boards.

What does the 5 Gbps throughput mean when the cable is installed in my PC?

It delivers up to 5 Gbps transfer speed when both the motherboard header and the connected device support USB 3.0, which is ten times faster than USB 2.0.

Which USB standard does the 20-pin header use and what does it limit in practice?

The header follows the USB 3.0 base specification, capping real-world throughput at 5 Gbps and providing two Type-A ports for front-panel access.
