Product information

Description

The StarTech PEXUSB3S25 PCIe USB 3.0 Card Adapter adds two SuperSpeed USB 3.0 ports to a PCI Express-enabled desktop or small form-factor computer. The card supports USB 3.0 data rates up to 5 Gbps, is backward compatible with USB 2.0/1.1 devices, and includes an optional LP4 power connector to provide up to 900 mA per port for bus-powered USB 3.0 devices (500 mA for USB 2.0). The adapter ships with both a full‑height and a low‑profile bracket for flexible installation.

Advantages

The PCIe USB 3.0 controller supports UASP (USB Attached SCSI Protocol) to improve throughput and reduce processor load compared with traditional USB Bulk‑Only Transport; in StarTech testing UASP delivered up to 70% faster read and 40% faster write performance and reduced CPU usage by up to 80% under peak conditions. The dual‑profile design fits standard and small form‑factor cases, and the optional LP4 power input enables reliable operation of higher-power USB devices.

Suitable for

Adding two USB 3.0 ports to desktop or small form‑factor PCs
Connecting external SSDs, HDDs, and high‑speed USB storage enclosures
Providing extra ports for USB peripherals that require higher power
Upgrading systems to USB 3.0 / USB 3.2 Gen 1 speeds

How to use

Power down and unplug the computer, open the case, and install the PCIe card into an available PCI Express slot. Secure the card with the bracket screw and attach either the full‑height or low‑profile bracket as required by your chassis. If connecting bus‑powered devices that need additional current, attach the system power supply using the optional LP4 (Molex) connector. Close the case, power on the system, and install any necessary drivers for your operating system. For best performance with UASP, use a UASP‑capable operating system and UASP‑enabled storage enclosure.

Usage recommendations

For optimal transfer speeds and reduced CPU usage, use the card with UASP‑capable devices and an operating system that supports UASP (for example Windows 8/8.1/10/Server 2012 and later or Linux kernel 2.6.37+). When installing in small form‑factor systems, ensure you use the included low‑profile bracket and confirm available PCIe lane type and space before installation.
