Internal PCIe interface card CHIEFTEC 81291 — PCIe host and PCIe output, Height 32 mm, 1 pc

CHIEFTEC 81291 is an internal PCIe interface card designed to provide an additional PCIe host and PCIe output connection inside a desktop or server chassis. With a compact 32 mm height, the card fits systems that require low-profile expansion hardware and is supplied as a single unit in retail packaging. The product is intended to extend or reroute PCIe connectivity where space is limited and standard-height cards are unsuitable.

Advantages

The card's low-profile 32 mm height enables installation in small form-factor and low-clearance systems without altering other components. Having both a host and an output PCIe interface simplifies cascading or extending PCIe lanes within the chassis. As an internal component, it allows direct board-to-board connectivity, reducing external cabling and potential signal loss. Supplied as a single unit, the card is ready for immediate installation and integration into existing internal PCIe layouts.

Suitable for

• Small form-factor desktops and HTPC builds that require low-profile PCIe expansion
• Server racks and rackmount systems with restricted internal clearance
• Systems where PCIe lanes need to be extended or rerouted internally
• Upgrading or modifying internal PCIe topology without using external adapters

Key specifications

• Form factor: internal low-profile PCIe interface card
• Height: 32 mm
• Interfaces: PCIe host input and PCIe output
• Quantity: single unit supplied in retail packaging

How to use

Power off the system and open the chassis according to the manufacturer's instructions. Identify a compatible PCIe slot or mounting point for the host connection and install the card securely, ensuring the 32 mm profile clears adjacent components. Connect the PCIe output to the target device or daughterboard as required. Verify all connections, close the chassis, and power on the system. Install any necessary drivers or firmware updates for the devices connected through the new PCIe interface.

Usage recommendations

Confirm system compatibility before installation by measuring internal clearance and checking motherboard or backplane PCIe lane availability. Avoid forcing the card into position; if resistance occurs, recheck alignment and mounting points. For optimal signal integrity, use short, direct internal connections and follow ESD precautions when handling the card.
