Manw USB 3.0 19Pin to Dual USB 2.0 9Pin Splitter Cable

SKU CH-QT0S-JBRAQ

Splits one 19-pin USB 3.0 motherboard header into two USB 2.0 9Pin ports running at 480Mbps for extra internal connections

  • Converts one 19Pin USB 3.0 header into two USB 2.0 ports
  • Delivers 480Mbps bandwidth for front panel USB and internal peripherals
  • Gold-plated pin terminals prevent poor contact inside the PC case
  • Compact internal design saves limited motherboard header resources
  • Driver-free plug-and-play installation for desktop assembly and upgrades

USB 3.0 Header to Dual USB 2.0 Splitter

This adapter converts a single motherboard 19Pin USB 3.0 internal header into two independent USB 2.0 9Pin female ports. It is designed for PC builders who have exhausted their native USB 2.0 headers during a case refit or hardware upgrade. The compact Y-type cable installs internally without any driver requirement. It provides a practical way to expand front-panel connectivity or connect internal accessories.

Runs at USB 2.0 480Mbps Bandwidth

The splitter operates under the USB 2.0 specification, limiting each port to 480Mbps transfer speed regardless of the source header version. Gold-plated pin terminals are used to maintain reliable contact and prevent intermittent connections inside the chassis. This bandwidth suits front panel USB ports, RGB controllers, fan hubs and similar low-speed internal peripherals. Higher-speed USB 3.0 devices will not benefit from the 3.0 header's potential throughput.

Suits Builders Needing Extra USB 2.0 Headers

This cable suits anyone adding front USB ports, lighting controllers or other internal USB 2.0 devices when the motherboard lacks sufficient 9Pin headers. It is not for users who require USB 3.0 transfer rates for internal drives or high-speed peripherals. Builders without a spare 19Pin USB 3.0 header on their motherboard cannot use this adapter. Buyers who want more storage or need to connect high-bandwidth internal devices should look at other solutions.

Questions about this item

What does the 480 Mbps bandwidth mean for devices plugged into the two ports?

The 480 Mbps limit is shared between both USB 2.0 ports, so each connected device runs at standard USB 2.0 speed and total throughput cannot exceed that figure.

Which header standard does the 19-pin plug connect to and what speed does it actually deliver?

The 19-pin plug fits a motherboard USB 3.0 internal header, but the adapter only passes USB 2.0 signals, capping every port at 480 Mbps regardless of the header version.

What motherboard header and case clearance does the splitter need to install?

It requires one free 19-pin USB 3.0 header on the motherboard and enough space behind the front panel for the compact Y-cable and two 9-pin female connectors.
