Connectivity for PC builders

This cable adds two USB 3.0 Type-A ports to a desktop by connecting a 20-pin motherboard header to dual male plugs. It suits builders who want front-panel or external access without opening the case for every device.

Passive operation

The copper construction carries signals without active electronics, so it draws no extra power and adds no fan noise. Thermals are unaffected because the adapter simply extends the existing header connection.

Replaces missing front ports

It upgrades systems that lack usable front-panel USB 3.0 headers or have damaged connectors. The jump is worth it when the board has a spare 20-pin header but the chassis provides no matching ports.

Questions about this item

How do I connect the 20-pin header to the motherboard correctly?

Align the 20-pin female header with the motherboard USB 3.0 header, matching the missing pin to the blocked hole; press straight down until it seats fully.

Will the copper conductors or connectors need replacement over time?

The copper construction and USB 3.0 Type-A male jacks are passive; no scheduled maintenance or replacement is required under normal use.

What throughput limit appears first during sustained large-file transfers?

The USB 3.0 interface caps sustained throughput at 5.0 Gbps (500 MB/s), which is the first bottleneck you will encounter.
