Internal USB 3.0 header adapter

This cable converts a single motherboard 20 pin header into two external USB 3.0 ports. It is intended for builders adding front-panel or bracket-mounted connectors to a desktop chassis. The screw-mount female ends allow secure attachment to a panel or bracket. The 40 cm length suits typical mid-tower routing from the header to the front.

Thermals noise and power

The assembly is a passive copper cable with no active components, so it generates no heat and produces no audible noise. It draws no auxiliary power beyond the 5 V supply already provided by the motherboard header. Normal operation adds no measurable thermal load inside the case.

Mounting hardware benefit

Two pre-drilled screw holes on each female connector let you fasten the ports firmly to a bracket or case cut-out without adhesives or friction-fit clips. This prevents the ports from pushing inward when a device is inserted and keeps the alignment stable over repeated plug cycles. No software or driver installation is required for the cable itself.

Questions about this item

How do I mount the dual USB 3.0 ports to a case panel using the screw holes?

Align the two screw holes on the female USB 3.0 bracket with the panel cut-out, insert screws through the holes, and tighten them to secure the ports before connecting the 20-pin header to the motherboard.

Will the 40 cm cable reach a front-panel cut-out on a full-tower chassis?

The 40 cm length is designed for standard mid-tower front-panel layouts; measure the routing path from the motherboard 20-pin header to the cut-out to confirm it reaches without tension.

What limits sustained transfer speed when both ports are used simultaneously?

Both ports share the single 20-pin USB 3.0 header bandwidth, so simultaneous heavy transfers on the two ports will be limited by that shared 5 Gbps upstream link.
