Ruth's sister Front PCI-E To 19/20 Pin Header Adapter internal power cable
Adds two internal USB 3.0 ports to a front-panel 19-pin header via a PCI Express 2.0 x1 card with 5 Gbps throughput
- Adds two front-panel USB 3.0 ports via 19-pin header
- Connects to PCIe slot for 5000 Mbps throughput
- Works with USB 2.0 and 1.1 devices automatically
- Draws power from the slot, no extra cable needed
- Uses xHCI 0.95 controller for stable operation
Front PCI-E To 19/20 Pin Header Adapter
This adapter connects a motherboard PCI Express slot to an internal 19-pin USB 3.0 header. It adds two front-panel USB 3.0 Type-A ports without requiring an external power connector. The card complies with the USB 3.0 Specification Revision 1.0 and PCI Express 2.0. A control chip enables 5 Gbps super-speed operation.
Builders adding front USB 3.0 ports
Suitable for desktop builders whose chassis has a 19-pin header but no front USB 3.0 ports. The xHCI 0.95 controller supports hot-plug and supplies up to 5 V 900 mA per port. Not suitable for systems lacking a free PCI Express slot or a 19-pin front-panel header. Buyers who need more than two additional ports should look elsewhere.
Dual-port 5 Gbps USB 3.0 expansion
The single specification that decides fit is the 19-pin internal header on the motherboard or front-panel module. Without that exact header the card cannot be connected. The adapter delivers two USB 3.0 ports at 5000 Mbps and remains backward compatible with 480 Mbps and 12 Mbps devices.

Questions about this item
Does the adapter draw extra power or generate noticeable heat when the front-panel USB 3.0 ports run at 5000 Mbps all day?
No external power supply is required; the adapter takes up to 5 V 900 mA from the PCI Express slot, so heat and power draw stay minimal during continuous 5 Gbps transfers.
What must already be inside the case for this 19-pin header adapter to work?
A free PCI Express 2.0 slot and a motherboard USB 3.0 19-pin internal header are needed; the card plugs into the slot and the header cable connects to the board.
Will the card work alongside older USB 1.1 peripherals that only manage 12 Mbps?
Yes, the controller is downward compatible with USB 1.1 and 1.0, so legacy devices still enumerate at 12 Mbps or 1.5 Mbps while the front-panel ports run at 5 Gbps.
