PCIe USB 3.0 Card Inateck KTU3FR-4P — 4 USB 3.0 Ports, 15‑pin SATA Power

Inateck KTU3FR-4P is a PCIe USB 3.0 expansion card that provides four external SuperSpeed USB 3.0 ports for a desktop PC. The card installs into a standard PCIe x1 (or larger) slot and uses a 15‑pin SATA power connector to supply stable additional power to connected devices. It extends a system's high-speed data transfer capability and offers backward compatibility with USB 2.0 devices, making it a practical I/O upgrade for workstations, home PCs and small office systems.

Advantages

The card offers four independent USB 3.0 ports with SuperSpeed data transfer rates and a SATA power input to ensure sufficient power delivery to multiple external drives and peripherals. Installation requires only a free PCIe slot and a SATA power cable from the power supply, enabling a compact and cost-effective expansion. The device supports plug-and-play operation under common desktop operating systems and maintains USB 2.0 compatibility for older devices.

Suitable for

• Adding high-speed external ports for external HDDs and SSD enclosures
• Connecting multiple USB peripherals (keyboards, mice, printers) while preserving native ports
• Powering and using USB hubs or card readers that require stable power
• Upgrading older workstations or home PCs to USB 3.0 performance
• Backup and data transfer tasks that benefit from SuperSpeed throughput

Key specifications

• Interface: PCI Express x1 compatible (fits x1, x4, x8, x16 slots)
• Ports: 4 × USB 3.0 Type-A external ports (SuperSpeed)
• Power input: 15‑pin SATA power connector for external power support
• Data rates: USB 3.0 SuperSpeed up to 5 Gbps (backward compatible with USB 2.0/1.1)
• Form factor: Low-profile bracket included (suitable for small form factor cases)

How to use

Power down the PC and open the case. Insert the card into an available PCIe x1 (or larger) slot and secure it with the bracket screw. Connect a free 15‑pin SATA power cable from the system power supply to the card's power connector. Close the case, power on the computer and allow the operating system to detect the new hardware. If necessary, install drivers provided by the operating system or the card manufacturer. After installation, connect USB devices to the external Type-A ports for SuperSpeed transfers and normal operation.

Recommendations

Use the SATA power connection when connecting multiple powered devices or high-draw external drives to ensure stable operation. For optimal throughput, connect devices directly to the card's USB 3.0 ports rather than through additional unpowered hubs. Ensure proper airflow inside the case and secure mounting to reduce the risk of connection issues.
