USB 3.0 19-Pin to 9-Pin Header Adapter: Does It Work?

USB 3.0 19-pin to USB 2.0 9-pin motherboard header adapter

Photos coming soon.

The short version

Buy it if

Builders moving an older motherboard into a case with USB 3.0 front ports
Anyone whose front USB ports are dead because the board lacks a 19-pin header

Skip it if

You need USB 3.0 transfer speeds from the front ports
Your motherboard manual lists a flexible USB 2.0 header that accepts a front USB 3.0 panel directly

What owners like

Forum answers confirm it gets front USB 3.0 ports working on a board with only USB 2.0 headers
Straightforward fix when the case and motherboard headers do not match

Common complaints

Front ports drop to USB 2.0 speed, and USB 3.0 devices fall back to the slower standard
Some buyers did not need one, because certain boards, such as some ASRock models, have a flexible USB 2.0 header that already accepts a front USB 3.0 panel

Based on two Tom's Hardware forum threads on fitting USB 3.0 front panels to USB 2.0 boards, and the retailer listing.

What it does

A short generic internal cable that lets a PC case's USB 3.0 front panel plug into a motherboard that only has USB 2.0 9-pin headers.

Adapts the connector only, it does not add USB 3.0 capability
Short internal lead that stays tucked inside the case
No drivers or software needed
Sold by several generic brands, often in 2 or 3 packs

A cheap, simple fix for building an older or budget motherboard into a newer case whose front USB ports use the blue 19-pin plug. The trade-off is speed: the front ports run at USB 2.0 rates of 480 Mbps, so anyone who needs USB 3.0 speeds from the front needs a PCIe card with an internal 19-pin header instead.

How it compares

SIIG LB-US0214-S1 USB 3.0 PCIe card with 19-pin headerGives the front panel real 5 Gbps USB 3.0 speed through a PCIe x1 slot, at a higher cost$$

Motherboard side: USB 2.0 9-pin female (fits the board's 9-pin header)
Speed: USB 2.0, up to 480 Mbps
Length: About 15 cm
Cable: Shielded, PVC jacket, moulded connectors

Worth knowing

Listings come in 19-pin male and 19-pin female versions; match the gender to your case cable and motherboard header

Questions

Can a USB 3.0 front panel cable plug into a USB 2.0 header?

Not directly, the plugs are different. An adapter like this makes the connection, and the ports then run at USB 2.0 speed.

Will this make the front ports USB 3.0 fast?

No. It only adapts the connector, so speed tops out at USB 2.0 rates of 480 Mbps.

Which gender is the right one?

For a case's 19-pin plug going to a board's 9-pin header, look for 19-pin male to 9-pin female. Listings are sold in both genders, so check before buying.

How to get real USB 3.0 on the front panel?

Add a PCIe USB 3.0 card that has an internal 19-pin header, such as the SIIG LB-US0214-S1, and plug the case cable into that.
