Internal interface card DeLOCK 81500 PCIe x1 1x USB 3.0

The DeLOCK 81500 PCIe x1 internal interface card adds a single USB 3.0 port to desktop systems via a PCI Express x1 slot. Designed for straightforward installation inside a PC chassis, this expansion card increases connectivity and enables faster data transfer to external storage devices, peripherals and mobile devices that support USB 3.0. The card is intended for users who need an extra external USB port or wish to upgrade older systems lacking native USB 3.0 support.

Advantages

The internal interface card provides a plug-and-play solution for adding USB 3.0 capability without replacing the motherboard. It supports high-speed USB 3.0 data rates and maintains backward compatibility with USB 2.0 and USB 1.1 devices, ensuring broad device interoperability. Its low-profile bracket option and PCIe x1 form factor make it suitable for compact systems while keeping installation simple and unobtrusive.

Suitable for

• Upgrading older desktop PCs to add USB 3.0 connectivity
• Connecting external hard drives, SSDs, and flash drives for faster transfers
• Adding an external USB port for peripherals such as printers, webcams or card readers
• Small form-factor or low-profile systems requiring a compact expansion card

Key specifications

• Interface: PCI Express x1
• External ports: 1 × USB 3.0 Type-A
• Data transfer: USB 3.0 SuperSpeed rates (up to 5 Gbps, dependent on host and device)
• Compatibility: Backward compatible with USB 2.0 and USB 1.1 devices
• Form factor: Low-profile compatible with an available full-height bracket
• Power: Bus-powered via PCIe slot; may require external power for some high-draw devices depending on system
• Mounting: Internal installation into a PCIe x1 slot

How to use

Install the DeLOCK 81500 into an available PCIe x1 slot on the motherboard and secure it with the chassis bracket screw. If the card includes a replaceable low-profile bracket and your case is compact, fit the appropriate bracket before mounting. After physical installation, start the system and install any required drivers provided by the operating system or the manufacturer. Once recognized, connect USB 3.0 devices to the Type-A port; the system will handle device enumeration and data transfer according to USB standards.

Recommendations

For optimal performance, connect USB 3.0-compatible devices and use high-quality USB 3.0 cables. If you plan to use externally powered high-current devices (such as some external hard drives or bus-powered hubs), verify your system’s power availability or use externally powered peripherals. Keep motherboard BIOS and system drivers updated to ensure compatibility and stability.
