Seven-port USB 3.0 expansion card for desktop PCs

This PCI-Express add-in card adds seven USB 3.0 ports to a desktop computer, letting users connect multiple external drives, peripherals or accessories at once. It fits a standard PCIe slot and targets builders who need more high-speed USB ports than their motherboard provides.

PCI Express 2.0 x1 interface with dual NEC chipset

The card conforms to the PCI Express 2.0 standard and uses a dual NEC chipset to deliver seven independent USB 3.0 channels. Each port supports the USB 3.0 specification with a 5 Gbps signalling rate and remains backward compatible with USB 2.0 and 1.1 devices.

Two onboard power modules supply 5 V / 2 A per port

Integrated power modules provide up to 2 A of 5 V current to each USB port, so external hard drives or charging devices can operate without an extra power adapter. The card includes drivers certified for 32-bit and 64-bit Windows XP, 7, 8, 8.1 and 10 as well as Linux.

Questions about this item

What does the 5Gbps rate actually deliver when the card is installed in a desktop?

The 5Gbps figure is the USB 3.0 signalling ceiling; real-world throughput depends on the host PCIe 2.0 lane, the connected devices and cable quality, so sustained transfer speeds will typically sit below that maximum.

Which PCI Express standard does the card use and how does it limit bandwidth?

The card conforms to PCI Express 2.0, so a single lane caps at 5GT/s; this matches the USB 3.0 5Gbps target but leaves no headroom for multiple ports running at full speed simultaneously.

What slot and power connections are needed to mount the card?

It requires a free PCI Express x1 (or larger) slot and draws all required power from the two onboard power modules, so no extra power cable from the PSU is necessary.
