Internal USB 3.0 header splitter

The Lirealar cable turns one motherboard USB 3.0 19/20 pin header into two female ports using a 1 to 2 Y splitter design. It is built for DIY builders who need extra internal USB 3.0 connections for front-panel ports or SLI configurations. The 5.9 inch flat ribbon keeps routing tidy inside the case.

Single-header expansion limit

Only one USB 3.0 19/20 pin male connector plugs into the motherboard, so total bandwidth stays at 5Gbps shared across both female ports. The supplier notes the header fit can be loose on some boards because pin layouts differ slightly. Buyers who need more than two ports or guaranteed tight retention on every motherboard cannot use this cable.

Sustained full-duplex transfer

The flat ribbon carries four differential signal pairs that support simultaneous bi-directional data flow at up to 5Gbps. Black ribbon construction resists heat build-up better than individual crimped wires during long file moves or continuous device syncing. Signal integrity holds without the degradation seen on loose, round-wire adapters under extended load.

Questions about this item

What does the 5 Gbps transfer rate mean for real-world file copies?

The cable carries USB 3.0 signals at up to 5 Gbps, so connected front-panel ports or devices can reach typical USB 3.0 speeds of several hundred megabytes per second in actual use.

Which header standard does the 19/20 pin connector follow and what does it limit?

It uses the standard USB 3.0 19/20 pin motherboard header, which caps the link at 5 Gbps and provides two downstream ports from one header.

How much clearance does the 5.9 inch flat ribbon need inside the case?

The 5.9 inch black flat ribbon is thin and flexible, so it fits behind motherboard trays or along cable channels without blocking airflow or larger components.
