Add two internal USB 3.0 headers

This PCIe x1 card adds two 19-pin USB 3.0 headers to a desktop with a free PCIe slot. Each header can feed two front-panel or internal ports for up to four USB 3.0 connections. The VL805 controller handles the conversion and fits x1, x4, x8 or x16 slots. It draws power from the slot so no extra cable is required.

Sustained 5 Gbps per header

Both headers share the single PCIe x1 lane and the VL805 controller rated for 5 Gbps SuperSpeed. Under continuous load the bus caps aggregate throughput at that rate, so simultaneous heavy transfers on all four ports will contend for the same bandwidth. The card needs no external power, so thermal limits follow the slot specification rather than a dedicated supply.

PCIe x1 lane and USB 2.0 fallback

The x1 interface sets a hard ceiling of 5 Gbps total across both headers, and the card will not fit a legacy PCI slot. Connected devices fall back to USB 2.0 at 480 Mbps or USB 1.1 at 12 Mbps when SuperSpeed is unavailable. Supported operating systems include Windows XP through Windows 10, so newer releases may require unverified drivers.

이 상품에 대한 질문

Does the VL805 chipset draw extra power or run hot when both 19-pin headers are active all day?

No external power supply is needed and the card draws all power from the PCIe x1 slot, so heat and power stay within slot limits.

What must my motherboard already have for the two 19-pin headers to work?

A free PCIe x1, x4, x8 or x16 slot and internal 19-pin USB 3.0 front-panel connectors on the case or board.

Will USB 1.0 and 2.0 devices plugged into the new headers still transfer at their original 1.5, 12 or 480 Mbps speeds?

Yes, the VL805 controller is backwards compatible with USB 1.0, 1.1 and 2.0, so legacy devices keep their native transfer rates.
