Description
Product Overview
The StarTech.com PEXUSB3S4V is a high‑performance PCI Express expansion card designed to bring the latest USB 3.0 technology to legacy and modern desktop computers alike. Built around a robust Intel chipset, the card provides four external SuperSpeed ports that operate at up to 5 Gbps, a tenfold increase over traditional USB 2.0 speeds. The inclusion of UASP (USB Attached SCSI Protocol) means that multiple data commands can be processed simultaneously, dramatically reducing latency and improving overall throughput for demanding workloads such as large file transfers, video editing, and backup operations.
Beyond raw speed, the card is engineered for reliability and power efficiency. Each port is equipped with a dedicated SATA‑derived power connector capable of delivering up to 900 mA per port, which is sufficient to power high‑draw devices such as external hard drives, docking stations, and even some charging‑intensive peripherals. The card’s low‑profile, stacked port layout ensures that all four ports are externally accessible while occupying minimal internal space, making it an ideal upgrade for compact or space‑constrained chassis.
Compatibility is a core strength of the PEXUSB3S4V. It works seamlessly with Windows 7, 8, 10, and the latest server editions, and it remains fully backward compatible with USB 2.0 and 1.x devices. The card’s silver finish matches standard motherboard aesthetics, and its 3 × 0.7 × 2.7 inch dimensions allow it to fit into most standard ATX, micro‑ATX, and mini‑ITX motherboards without requiring additional brackets. With a modest price point of $41.79, it offers a cost‑effective path to modern connectivity for both home users and professional environments.
Usage
In a typical office setting, the PEXUSB3S4V enables rapid synchronization of large data sets between workstations and network‑attached storage devices. Users can connect external SSDs, high‑capacity HDDs, and USB‑C peripherals directly to the card, reducing transfer times from minutes to seconds. The card also excels in creative studios where large media files are commonplace; video editors can move raw footage to external drives with minimal interruption, and graphic designers can stream high‑resolution assets without bottlenecks.
For gamers and home entertainment enthusiasts, the card provides a reliable conduit for VR headsets, high‑definition webcams, and fast‑charging game controllers. Its ability to supply ample power means that even power‑hungry accessories operate without the need for separate power adapters, keeping desk space tidy and reducing cable clutter. The card’s plug‑and‑play nature ensures that installation is straightforward: simply insert the card into an available PCIe slot, connect the SATA power cable, and install the driver software provided by StarTech.com.

FAQ
Will this card work with my older motherboard?
Yes. The PEXUSB3S4V uses a standard PCI Express x1 slot, which is present on most motherboards released in the last decade. Even if your system only supports PCIe 2.0, the card is fully backward compatible and will operate at the appropriate speed.
Do I need to install drivers?
While Windows 10 and newer operating systems include generic drivers that allow basic functionality, we recommend installing the specific StarTech.com driver package for optimal performance, especially to enable UASP support and ensure stable power delivery.
Can I use this card to charge my smartphone?
Absolutely. Each port can provide up to 900 mA of power, which is sufficient to charge most smartphones, tablets, and other USB‑C devices at a reasonable rate. For devices that require higher current, the card still supplies the standard 500 mA for USB 2.0 compatibility.
Is the card covered by a warranty?
StarTech.com offers a limited one‑year warranty on the PEXUSB3S4V, covering any manufacturing defects. In addition, the company provides a 30‑day money‑back guarantee if the product does not meet your expectations.
