Product Features
Technical Overview
This USB PCIe card operates through a PCI Express x4 host interface, delivering a maximum data transfer rate of 1.25 GB/s (10Gbps) across all connected ports. The card supports USB 3.2 Gen 2 specifications, maintaining backward compatibility with earlier USB standards while providing modern connectivity options.
The card features intelligent power management with an optional SATA power connector that supplies additional power when motherboard power is insufficient. This enables the USB-C ports to deliver up to 5V 3A (15W) per port and the internal USB-A port to provide 5V 1.5A (7.5W), supporting power-hungry devices without compromising system stability.
Relevant factors for this section include Host Interface, Data Transfer Rate. When those points are considered together, they give buyers a clearer picture of how the product is equipped, how it fits into deployment, and what kind of day-to-day role it is meant to support.

User Manual
FAQ
What types of systems is this USB PCIe card compatible with?
This card works with desktop and server systems that have an available PCI Express x4, x8, or x16 slot. It supports Intel, AMD, and Apple Silicon platforms, and includes both standard and low-profile brackets for installation in full-size towers and compact small form factor systems. The card is compatible with Windows 7 through 11, Windows Server 2008 R2 through 2022, macOS 10.13 through current versions, and Linux 3.5 and newer.
What is the purpose of the SATA power connector on this card?
The SATA power connector provides additional power to the USB ports when motherboard power through the PCIe slot is insufficient. When connected, it enables the USB-C ports to deliver up to 5V 3A (15W) per port and the internal USB-A port to provide 5V 1.5A (7.5W). This ensures stable operation with power-hungry devices like external hard drives, multiple peripherals, or charging devices without drawing excessive power from the motherboard.
Does this card support USB Power Delivery or DisplayPort Alt Mode?
No, this card does not support USB Power Delivery (PD) or DisplayPort Alt Mode (DP-Alt Mode). It provides standard USB 3.2 Gen 2 data transfer capabilities at 10Gbps with enhanced power delivery through the optional SATA connection, but it cannot charge devices using USB PD protocols or transmit video signals through the USB-C ports. For those features, you would need a different expansion card specifically designed with those capabilities.
What operating systems are supported without manual driver installation?
Most modern operating systems automatically install drivers for this card. Windows 8, 8.1, 10, and 11 typically recognize the card immediately, as do recent versions of macOS (10.13 High Sierra and newer) and Linux distributions with kernel 3.5 or later. For Windows 7 and specific server editions, you may need to download drivers from the manufacturer's website, though the card remains fully compatible with these systems.
Can I use this card in a small form factor desktop or server?
Yes, the card includes both a pre-installed full-profile bracket and an additional low-profile bracket specifically for small form factor (SFF) systems. The low-profile bracket allows installation in compact desktop cases and server chassis with limited vertical clearance. The card's compact dimensions (4.8" x 4.8" x 0.9") and lightweight design (2.1 oz) make it suitable for space-constrained environments without compromising performance.
What is the warranty coverage for this USB PCIe card?
StarTech.com provides a 2-year limited warranty for this product. The warranty covers defects in materials and workmanship under normal use. The card is also RoHS and WEEE compliant, meeting environmental standards for hazardous substance restrictions and electronic waste management. For warranty service or support, you can contact StarTech.com directly through their official support channels.
