Manw USB 2.0 9-Pin to Type-E 20-Pin Header Adapter (Type A)

SKU CH-266A-C5VF6

Converts a motherboard USB 2.0 9-pin header to a front-panel Type-E 20-pin connector with a USB 2.0 Type-A female port, limited to 480Mbps

  • Converts motherboard USB 2.0 9-pin header to front-panel Type-E 20-pin connector
  • Provides USB 2.0 Type-A female output for legacy device compatibility
  • Delivers 480 Mbps transfer rate matching native USB 2.0 specification
  • Requires motherboard or expansion card with 9-pin 2.54 mm socket
  • Cannot increase speed beyond USB 2.0 due to 9-pin interface limitation

USB 2.0 header adapter for front-panel Type-E ports

This adapter converts a motherboard USB 2.0 9-pin header into a front-panel Type-E 20-pin connector with an A-key layout. It is intended for builders whose case provides a USB 3.2 Type-E front cable but whose board only offers legacy 9-pin USB 2.0 headers. The device requires a motherboard or expansion card with a 9-pin 2.54 mm socket and a chassis equipped with a Type-E cable. It adds no new controller; it only re-routes the existing USB 2.0 signals.

480 Mbps throughput ceiling with USB 2.0 headroom

The adapter passes USB 2.0 data at up to 480 Mbps, which is the native rate of the 9-pin source header. Because the input is limited to USB 2.0 signalling, the Type-E output cannot exceed this speed and will not accelerate transfers to USB 3.2 levels. It comfortably handles keyboards, mice, printers and USB 2.0 flash drives connected to the front panel. It runs out of headroom for high-bandwidth devices such as external SSDs or video capture gear that need SuperSpeed rates.

A-key Type-E pin-out decides mechanical fit

The single specification that determines compatibility is the A-key pin arrangement on the Type-E 20-pin output. Only front-panel cables or enclosures wired to the same A-key layout will mate correctly; B-key or differently keyed Type-E connectors will not align. No other electrical parameter overrides this mechanical constraint, so verifying the case cable keying against the adapter’s A-key design is the decisive step before purchase.

Questions about this item

Will the Manw adapter work with my motherboard's existing USB 2.0 9-pin header?

Yes, it plugs into any standard USB 2.0 9-pin header with 2.54 mm pitch and converts it to a front-panel Type-E 20-pin connector.

How can I confirm the adapter is delivering USB 2.0 speeds after installation?

Connect a USB 2.0 device to the Type-A female port and verify the system reports a 480 Mbps link speed in Device Manager or lsusb.

Does the package include the Type-E cable for my chassis front panel, or must I buy it separately?

The adapter only provides the Type-E 20-pin header; the chassis Type-E cable is not included and must be sourced separately.
