Front-Panel USB 3.0 Splitter

This adapter connects a single motherboard 19/20-pin USB 3.0 header to two front-panel ports: one 20-pin header and one Type-E header. It lets builders add extra USB 3.0 connectors to a case without using a second motherboard header. A SATA power cable is included to supply the additional port. The unit is built on a compact plastic PCB.

Builders adding front USB 3.0 ports

Suits anyone whose motherboard has only one 19/20-pin USB 3.0 header but whose case or hub needs both a 20-pin and a Type-E connection. It also helps when a single header must feed a card reader and a front panel at the same time. Not for systems that lack a 19/20-pin USB 3.0 header entirely, or for installations that require more than two downstream ports.

5 Gbps shared bandwidth

The splitter delivers up to 5 Gbps total throughput, shared between the two output ports. Simultaneous transfers on both ports will divide this bandwidth. If your workflow demands full 5 Gbps on each port at once, a motherboard with two native headers is the appropriate choice.

Questions about this item

Should I pick the 19Pin or 20Pin header for my motherboard?

The adapter fits a single 19/20Pin motherboard header and splits it into one 20Pin and one Type-E front-panel port, so it works with either keying.

What does the 5Gbps rating mean for file transfers on this adapter?

It delivers USB 3.0 SuperSpeed up to 5Gbps, roughly ten times the throughput of USB 2.0, with simultaneous two-way data flow.

Does the SATA power cable affect the USB 3.0 data rate?

The SATA power lead only supplies extra current for connected devices; the USB 3.0 signalling remains at 5Gbps regardless.
