Two USB 3.0 Ports via PCIe

This StarTech.com PEXUSB3S23 expansion card adds two external USB 3.0 Type-A ports to a desktop computer through an available PCI Express x1 slot. The card supports SuperSpeed data rates up to 5.0 Gbps and includes an optional 15-pin SATA power connector that can supply up to 900mA per port for power-hungry peripherals. A low-profile bracket is supplied for installation in compact chassis.

Upgrade from USB 2.0 or Missing Ports

The card replaces older USB 2.0 add-in cards or fills the gap on motherboards that lack native USB 3.0 headers, delivering a tenfold increase in theoretical bandwidth to 5 Gbps. The jump is worthwhile when you regularly move large files to external drives, use high-speed docks, or need the higher current available from the SATA-powered ports for charging devices.

Check Slot, OS and Power Cable

Verify that your system has a free PCI Express x1 slot (or larger) and that you are running a supported Windows version such as Windows 7, 8, Vista, XP, Server 2003 or Server 2008 R2 in either 32-bit or 64-bit editions. Ensure a spare SATA power lead from the power supply can reach the card if you intend to use the optional 900mA per-port power feature.

Questions sur cet article

Does the PEXUSB3S23 fit a low-profile PCIe x1 slot?

Yes, the card includes a low-profile bracket and uses a PCI Express x1 male edge connector for half-height chassis.

How do I connect the optional SATA power plug on the PEXUSB3S23?

Attach a standard 15-pin SATA power cable from the PSU to the card's internal connector before closing the case; skipping this step limits each USB port to less than 900 mA.

When should I replace the driver CD supplied with the PEXUSB3S23?

The CD contains drivers for Windows XP through 8 and Server 2003/2008; download updated drivers from the manufacturer if you move to a newer OS.
