Internal Interface Card DeLOCK 81294 PCIe 1x to 4x

The DeLOCK 81294 Internal Interface Card PCIe 1x to 4x is an expansion adapter that converts a single PCIe 1x slot into four PCIe lanes, enabling additional PCIe devices to be installed in the same system. It is intended for desktop systems and workstations where extra internal connectivity is required without modifying the motherboard layout. The card supports simultaneous connections and provides a compact solution for adding multiple low- to moderate-bandwidth PCIe cards.

Advantages

This internal interface card offers a space-saving way to increase available PCIe lanes from one slot to four, allowing the installation of multiple peripheral cards without needing a larger motherboard. The passive adapter design reduces power and cooling complexity compared with active riser cards. Compatibility with standard PCIe 1x mechanical slots ensures broad fit in many chassis configurations, and the compact form factor helps maintain airflow and component access inside the case.

Suitable for

• Adding multiple low-profile PCIe cards such as network adapters, USB or SATA controllers
• Small-form-factor desktops and workstations needing additional internal expansion
• Systems where motherboard PCIe lane allocation is limited
• Test benches or development systems requiring flexible device swapping

Key specifications

• Interface type: PCI Express mechanical adaptation from 1x to four PCIe lanes
• Form factor: internal card designed for installation in PCIe-compatible slots
• Compatibility: designed for systems with available PCIe 1x mechanical slot
• Data transfer: supports standard PCIe signaling at the host slot’s supported generation
• Power: draws power through the host PCIe slot according to PCIe specifications
• Cooling and layout: compact design to minimize obstruction of internal airflow

How to use

Install the card into an empty PCIe 1x mechanical slot on a powered-down and unplugged desktop or workstation. Secure the card to the chassis and connect the desired PCIe daughter cards into the provided lanes according to their mechanical fit. After installation, power on the system and verify device detection in the operating system. If necessary, install or update drivers for each connected peripheral to ensure proper functionality. Follow static discharge precautions and the system manufacturer’s installation guidelines during the process.

Usage recommendations

Use this adapter primarily for adding low- to moderate-bandwidth devices; devices requiring full x4 bandwidth may be limited by the host slot’s generation and lane allocation. Ensure the host slot supports the required PCIe signaling speed for your devices and verify physical clearance inside the case before installation.
