From creative professionals moving large HD footage to IT admins juggling multiple external drives and hubs, this expansion card is built to deliver consistent 5Gbps performance across all four ports, helping you streamline workflows and boost productivity.

• Blazing-fast four-port USB 3.0 expansion: Each of the four ports delivers USB 3.0 (SuperSpeed) performance with theoretical transfer rates up to 5 Gbps, enabling rapid file transfers, quick backups, and smooth external playback. This makes it ideal for editing large video files, cloning drive images, moving 4K content, or syncing massive photo libraries with minimal wait times. By adding four independent USB 3.0 ports to a single PCIe slot, you can connect multiple high-speed devices without sacrificing throughput on any one device. Real-world speeds depend on your host system, USB devices, and cable quality, but the card is engineered to maximize performance across all ports simultaneously.
• Powerful SATA/SP4 power support for demanding devices: The integrated SATA/SP4 power connector provides additional current to power-hungry peripherals, such as external hard drives, USB-powered docks, or multi-port hubs. This reduces the risk of underpowered devices causing disconnects or slowdowns, and it helps maintain stable operation when multiple USB devices are connected at once. If your motherboard’s USB power capabilities are limited, this power option ensures you can run high-demand peripherals reliably without overburdening the PCIe bus. The card is designed to offer flexible power management for a broad range of setups, from home computing to professional workstations.
• PCIe-based upgrade with flexible form-factor support: This card is designed for desktops with available PCIe slots, offering an easy upgrade path for older systems that lack USB 3.0 ports. The PCIe interface enables higher bandwidth and compatibility with recent motherboards, while the included brackets accommodate both full-height slots in standard towers and low-profile configurations for compact cases. Whether you’re upgrading a legacy workstation, building a clean workstation for media tasks, or equipping a lab PC with modern USB connectivity, this card’s scalable design makes it a practical, long-term solution.
• Backward compatibility and broad device support: While delivering USB 3.0 speeds, the card remains backward compatible with USB 2.0 and 1.1 devices, ensuring you can connect older peripherals without issues. This makes the card a versatile upgrade for mixed-device environments, allowing you to preserve existing hardware while embracing faster data transfers for newer devices. Plug-and-play operation is supported on many systems, and driver availability ensures consistent performance across Windows and select Linux distributions, giving you flexibility in how you deploy the card within your environment.
• Easy installation, robust reliability, and versatile use cases: The card ships with essential accessories and offers straightforward installation for both beginners and advanced users. Its robust PCIe integration supports multiple use cases — from boosting a workstation for content creation and data backups to expanding a corporate PC fleet with additional USB ports for peripherals. The low-profile bracket option ensures compatibility with compact chassis, while the full-height bracket serves standard desktops, making this upgrade suitable for a wide range of builds. Whether you’re organizing a studio, lab, or home office, this card provides dependable USB performance with simple, scalable deployment.

How to install StarTech.com 4 Port PCI SuperSpeed USB 3.0 Adapter Card with SATA/SP4 Power

• Power down your computer and unplug the power cord to ensure safe installation and prevent electrical damage.
• Open the computer case to access the motherboard and locate a free PCIe slot (preferably PCIe x1 or higher) that is unobstructed by existing cards or cables.
• Remove the slot cover at the back of the chassis where the card will be mounted, creating the necessary opening for the expansion card’s ports.
• Insert the PCIe card firmly into the PCIe slot, applying even pressure until it is seated securely. Use a screw to fasten the card to the case if a mounting hole is present.
• Connect the SATA/SP4 power connector from your power supply to the card to provide additional power for high-demand devices. If you are not attaching power-hungry peripherals, you may still use the bus power, but the SATA power connection improves stability for external drives and hubs.
• Close the case, reconnect power, and boot the computer. Install the latest drivers from StarTech’s official site if prompted; many operating systems will recognize the card automatically, delivering plug-and-play functionality.
• After installation, connect USB devices to the four ports and verify that each device is recognized and capable of full USB 3.0 speeds. Test with files of varying sizes to confirm stable performance across all ports.
