SMUGDESK USB 2.0 to 3.2 Gen 1 Header Adapter 2-Pack

SKU CH-9ZDZ-DDKAT

Two-pack adapters convert a motherboard USB 2.0 header to a 20-pin Type-E connector for front-panel USB-C ports at up to 480 Mbps

  • Add front-panel USB-C without a Type-E header
  • Driver-free plug-and-play installation
  • Two adapters included for dual-port cases
  • Up to 480 Mbps transfer via USB 2.0 header
  • Compact 0.94 x 0.51 x 0.19 in design

USB 2.0 to 3.2 Gen 1 Header Adapter 2-Pack

This two-pack converts a motherboard USB 2.0 9-pin header into a USB 3.2 Gen 1 Type-E connector. It targets builders whose case front panel includes a USB-C port but whose board lacks a native Type-E header. Each adapter is plug-and-play with no driver installation required. The pack supplies two identical converters for dual-port cases or spare parts.

9-pin female to 20-pin A-key Type-E converter

The adapter bridges a standard internal USB 2.0 header to the 20-pin A-key Type-E socket used by modern front-panel USB-C ports. Its compact dimensions of .94 by .51 by .19 inches fit tight header zones without blocking adjacent connectors. Because the link runs over USB 2.0 wiring, the front-panel USB-C port operates at up to 480 Mbps rather than full 3.2 Gen 1 speed. The passive design needs no external power.

Check motherboard header

Verify your motherboard provides a free USB 2.0 9-pin header and that the case front-panel cable terminates in a USB 3.2 Gen 1 Type-E plug. This adapter will not work with USB 3.0 19-pin headers or proprietary case connectors. Transfer speed is limited to USB 2.0 rates, so users needing 5 Gbps throughput should confirm their board has a native Type-E header instead.

Questions about this item

What speed does the USB 2.0 9-pin header limit the front-panel USB-C ports to?

The adapter connects a 20-pin Type-E front-panel header to a USB 2.0 9-pin motherboard header, so the USB-C ports run at up to 480 Mbps.

Will the 0.94 × 0.51 × 0.19 in adapter fit behind a crowded front-panel PCB?

At 0.94 in long, 0.51 in wide and 0.19 in high, the low-profile board slips into tight front-panel cut-outs without fouling neighbouring headers.

Which way round does the 20-pin A-key plug go onto the case header?

The A-key notch on the 20-pin connector only mates one way; line up the missing pin with the key on the case header before pressing home.
