What this cable does

This Fervit adapter converts a USB 2.0 9-pin header into a USB 3.0 20-pin connection. It is intended for builders who need to link a modern front-panel or internal device to an older motherboard header. The reversible female connector simplifies installation by removing orientation concerns. The 20-pin housing helps shield the port from dust and debris.

What to verify before ordering

Confirm that your motherboard provides a standard USB 2.0 9-pin header for the input side of this cable. Check that the target device or front-panel module requires a USB 3.0 20-pin interface. Ensure there is enough physical space around the header to accommodate the housing. This adapter does not add USB 3.0 controller functionality where none exists.

Thermals noise and power

The cable is a passive wiring assembly with no active components, so it generates no heat and produces no audible noise. It draws no auxiliary power beyond the minimal signal current supplied by the motherboard header. Normal operation imposes no additional thermal load on the system. The 20-pin housing offers basic physical protection for the connected port.

Questions about this item

Does the package include both cables or do I need to order a second set?

The listing specifies 2pcs, so two adapter cables are supplied in one package.

Should I pick the 9-pin or the 20-pin end for my motherboard header?

Connect the 9-pin plug to the board's USB 2.0 header and the 20-pin receptacle to the device or front-panel cable.

Will plugging this into a USB 2.0 header actually give me USB 3.0 speeds?

No — the adapter only changes the physical connector; transfer rates remain at USB 2.0 levels.
