PCIe USB 3.0 controller card Renkforce 1211115 – 4 ports

The Renkforce PCIe USB 3.0 Controller Card (4 Ports) adds four external high-speed USB 3.0 ports to a desktop PC with an available PCI Express slot. Designed for straightforward expansion, this controller card enables faster data transfers for external hard drives, flash drives, printers and other USB peripherals, while maintaining compatibility with USB 2.0 devices. Installation is intended to be plug-and-play on systems with native driver support or simple driver setup on older operating systems.

Advantages

The card provides four external USB 3.0 Type-A ports, delivering up to 5 Gbit/s theoretical transfer speeds when paired with compatible devices. It supports backward compatibility with USB 2.0 and USB 1.1 peripherals, allowing a gradual upgrade of workstation connectivity. Its low-profile bracket option and standard bracket allow installation in a variety of desktop chassis. The PCIe interface ensures a direct host connection for stable throughput, and the compact design minimizes occupied space on the motherboard.

Suitable for

• Adding USB 3.0 ports to older desktop PCs or workstations
• Connecting external SSDs and HDDs for faster backups and file transfers
• Expanding port availability for printers, scanners and USB hubs
• Upgrading small office or home office systems requiring additional high-speed ports

Key specifications

• Interface: PCI Express x1 compatible
• External ports: 4 × USB 3.0 Type-A
• Maximum theoretical data rate: up to 5 Gbit/s per port (USB 3.0 specification)
• Backward compatibility: USB 2.0 / USB 1.1
• Form factor: low-profile bracket included (fits standard and small-form-factor cases)
• Bus power: powered by PCIe slot (no external power connector required in typical use)

How to use

Power down the computer, open the chassis and insert the card into an available PCIe x1 (or larger) slot. Secure the bracket and close the case. Boot the system and allow the operating system to detect and install drivers automatically, or install the driver supplied by the system or manufacturer if automatic installation does not occur. After installation, connect USB devices to the external ports and verify device recognition. For best performance, connect USB 3.0 devices using USB 3.0 cables and avoid routing through unpowered hubs when high throughput is required.

Recommendations

Use the card in a PCIe x1 or higher slot for optimal connectivity. Ensure the host operating system has appropriate drivers for USB 3.0 support. When transferring large files or performing backups, connect directly to the USB 3.0 ports with quality cables and avoid sharing bandwidth with multiple high-speed devices on the same bus to maintain transfer performance.
