What this cable does

The BUCIER 20 Pin Y Splitter adds two USB 3.0 Type-A ports to a desktop by connecting directly to a motherboard 20-pin header. It suits builders who need front-panel or internal USB access without occupying rear I/O slots. The 30 cm blue cable carries one 20-pin female header to dual USB 3.0 A female jacks in a single 1-pack.

Speed and compatibility limits

The link supports up to 5.0 Gbps (500 MB/s) with USB 3.0 devices and remains backward compatible with USB 2.0 and USB 1.1 peripherals. Bandwidth is shared between the two ports, so simultaneous high-throughput transfers will divide the available 5.0 Gbps. The 30 cm length restricts routing to nearby headers; longer runs need a different cable.

When to choose this adapter

This splitter upgrades a system that has a spare 20-pin header but lacks front USB 3.0 ports, replacing makeshift rear-panel cables or missing connectors. It is not for builds that require more than two additional ports, need external drive enclosures with dedicated controllers, or must route cables beyond 30 cm from the header.

Questions about this item

Will the 20-pin header on this Y splitter fit the USB 3.0 header on my older motherboard?

Yes, the 20-pin female header connects directly to a standard motherboard USB 3.0 20-pin header and is backward compatible with USB 2.0 and 1.1 peripherals.

How can I verify the cable is delivering USB 3.0 speeds after I plug it in?

Connect a USB 3.0 flash drive and check that the transfer rate approaches 5.0 Gbps (500 MB/s) in your operating system's file-copy dialog or benchmark tool.

Does the package include mounting brackets or screws for the two USB 3.0 Type-A ports?

The box contains only the 30 cm Y splitter cable with one 20-pin female header and two USB 3.0 Type-A female jacks; brackets and screws are not included.
