Splits one motherboard USB 3.0 header into two with a 5.9 inch flat-ribbon cable for 5Gbps internal connections

  • Connector TypeLighting Connector to USB A
  • Dual-header Y splitter adds a second USB 3.0 front-panel connection
  • 5 Gbps transfer rate keeps external drives at full speed
  • Full-duplex signalling enables simultaneous read and write traffic
  • 15 cm flat ribbon cable routes cleanly inside tight cases
  • Male 19/20-pin to female 19/20-pin fits standard motherboard headers

Internal USB 3.0 header splitter

This 19/20-pin Y-splitter cable turns one motherboard USB 3.0 header into two front-panel ports. It is aimed at PC builders adding extra case ports or running SLI setups that need additional header connections. The 5.9 inch flat ribbon keeps internal routing tidy and flexible.

5 Gbps transfer ceiling

The cable is rated for up to 5 Gbps data throughput, matching the USB 3.0 specification. It supports full-duplex, simultaneous bi-directional signalling across four differential pairs. Performance will not exceed this ceiling regardless of attached devices.

Two front-panel ports from one header

The splitter comfortably feeds two standard front-panel USB 3.0 connectors for everyday peripherals and storage. Bandwidth is shared, so heavy concurrent transfers on both ports will saturate the single 5 Gbps link. The short length limits placement to nearby headers only.

Questions about this item

What does the 5 Gbps transfer rate mean when the splitter is installed in a real system?

The 5 Gbps figure is the maximum theoretical throughput of the USB 3.0 link; actual file-transfer speeds depend on the connected drives, motherboard controller and system load.

Which USB standard does the 19/20-pin header follow, and what does that limit in practice?

The cable uses the USB 3.0 19/20-pin header standard, capping the link at 5 Gbps and requiring a matching motherboard header for operation.

What clearance or mounting space does the 5.9-inch flat ribbon need inside the case?

The 5.9-inch black flat ribbon is flexible enough to route behind the motherboard tray or along drive cages, needing only enough slack to reach two front-panel USB 3.0 ports.
