Splitter Cable for USB 3.0 Headers

This ShengEN splitter cable connects a single 19-pin motherboard header to two USB 3.0 20-pin ports. It is built for system builders who need to add front-panel USB 3.0 connectors when the board only provides one internal header. The 12cm length suits compact chassis routing.

Upgrade from Single-Header Limitations

The cable replaces a direct one-to-one header cable when a case offers two USB 3.0 front ports but the motherboard exposes only one 19-pin header. The jump is worth it when the builder wants both front ports active without adding a PCIe USB controller card. It draws power through the existing header so no extra power connection is required.

Dual-Port Headroom with 18AWG Conductors

The 18AWG wiring supports the current needed for two simultaneous USB 3.0 devices at standard specification. It comfortably handles flash drives, external SSDs and phone charging on both ports. Headroom runs out if multiple high-draw devices exceed the motherboard header's own current limit, which the cable cannot increase.

Questions about this item

Will the 12 cm cable reach my motherboard's 19-pin header from the front-panel USB 3.0 20-pin connectors?

The cable is 12 cm long; measure the distance between your motherboard's 19-pin header and the front-panel 20-pin ports to confirm reach.

Which side of the splitter plugs into the motherboard header and which side connects to the front panel?

Connect the single 19-pin end to the motherboard header and the two 20-pin ends to the front-panel USB 3.0 ports; reversing them will not work.

Does the 18 AWG wire need replacement after a certain number of insertions?

The 18 AWG conductors are rated for standard PC build cycles; no scheduled replacement is required unless physical damage or intermittent connectivity appears.
