Front-panel USB 3.0 splitter

This cable converts a single motherboard 19/20-pin header into two USB 3.0 Type-A ports with screw mounting holes. It suits builders adding front-panel connectivity to a custom case or replacing a damaged header cable. The 50 cm length reaches most mid-tower layouts without excess slack.

Sustained 5 Gbps throughput

Rated at 5 Gbps, the link maintains full USB 3.0 speed during large file transfers to external drives or high-resolution media reads. Backward compatibility with USB 2.0 at 480 Mbps ensures older peripherals still function when plugged into the same ports.

Replaces add-in expansion cards

Using the existing motherboard header avoids the cost and PCIe slot consumption of a separate USB controller card. The jump is worthwhile when the board has a spare 19/20-pin header and the case front panel lacks native USB 3.0 ports.

Questions about this item

Does the 50 cm cable add noticeable heat or power draw when the two USB 3.0 ports run all day?

The passive 50 cm extension draws no extra power and generates no measurable heat; it simply carries the motherboard’s existing 5 Gbps USB 3.0 signal to the front panel.

What must my motherboard already have for this 19/20-pin header splitter to work?

An internal 19-pin or 20-pin USB 3.0 header on the motherboard is required; the cable plugs directly into that header and provides two screw-mount Type-A ports.

Will USB 2.0 flash drives and wireless dongles still work at full 480 Mbps through the two front-panel ports?

Yes, the adapter is backward compatible with USB 2.0, so older peripherals operate at their native 480 Mbps without any configuration.
