Motherboard 20-pin to USB-C adapter

This EN-Labs adapter connects an internal motherboard USB 20-pin header to an external USB 3.1 Gen 1 Type-C female port. It mounts through a standard PCI slot cover bracket for a secure rear-panel installation. The 50 cm cable length suits typical chassis layouts.

Passive signal conversion

The adapter carries USB 3.1 Gen 1 signals without active components, so it draws no additional power and produces no noise. Thermals are irrelevant because the device simply routes the existing header lanes through the bracket.

Sustained 5 Gbps throughput

Under continuous load the link maintains the rated 5 Gbps data rate as defined by the USB 3.1 Gen 1 specification. Performance is limited by the motherboard header implementation rather than the adapter itself.

Questions about this item

How do I connect the 20-pin header to my motherboard and secure the bracket without bending the pins?

Align the keyed 20-pin connector with the motherboard USB header, press straight down until seated, then fasten the PCI slot cover bracket to the case with a single screw.

Will the Type-C female port or the 50 cm cable need replacement after repeated plugging cycles?

The Type-C female port is rated for standard insertion cycles; the fixed 50 cm cable assembly has no user-serviceable parts and is replaced as a unit if damaged.

What throughput limit appears first when transferring large files continuously at 5 Gbps?

Sustained transfers are capped by the USB 3.1 Gen 1 5 Gbps interface; real-world throughput will hit that ceiling before cable length or connector resistance becomes a factor.
