PCI Express to PCI Adapter Card StarTech PEX1PCI1 — PCIe host, 1x 32-bit PCI slot, red, 70×135×20 mm

StarTech PEX1PCI1 is a PCI Express to PCI adapter card that provides a single 32-bit low profile PCI slot via a PCIe host interface. Designed to install a half-height PCI interface card into a standard PCIe expansion slot, the adapter supports connections to legacy PCI and PCI-X cards from a modern PCIe 1x host. The card uses an integrated Pericom PI7C9X110BNBE chipset, includes a spare full-size bracket for larger systems, features an on-board LP4 power connector to support both 3.3V and 5V PCI cards, and is finished in red with compact dimensions of 70×135×20 mm.

Advantages

The adapter enables reuse of existing 32-bit PCI cards in systems that only provide PCI Express expansion, allowing legacy I/O to be retained without replacing functional PCI cards. Its compliance with PCI Express Specification 1.0a and PCI Specification 2.2 ensures standardized signaling and compatibility for supported cards. The built-in LP4 power connector supplies the necessary voltage options for universal PCI cards, while the included full-size bracket and a bracket design that secures low-profile cards simplify installation across desktops and servers. Certified CE, FCC and RoHS, the card provides a compact, low-cost interoperability solution.

Suitable for

• Installing a low profile 32-bit PCI interface card into a PCIe 1x slot
• Retaining legacy PCI or PCI-X I/O cards when upgrading motherboards
• Industrial or embedded systems requiring older PCI expansion
• Server or desktop environments needing a compact PCI expansion option

• Chipset: Pericom PI7C9X110BNBE
• Power: on-board LP4 connector for 3.3V/5V PCI cards
• Dimensions: 70 × 135 × 20 mm
• Weight: 0.052 kg
• Color: red
• Compliance: CE, FCC, RoHS

How to use

Power off the host system and open the chassis according to the manufacturer’s instructions. Install the adapter into an available PCIe x1 expansion slot and secure the bracket appropriate to the chassis using the included full-size or low-profile bracket as needed. Insert the 32-bit low profile PCI card into the adapter’s PCI slot and ensure it is firmly seated. Connect the system power supply to the adapter’s LP4 power connector if the installed PCI card requires board power at 3.3V or 5V. Close the chassis, power on the system, and allow the operating system to detect the added PCI device; install any required drivers for the PCI card.

Usage recommendations

Verify that the target PCI card is electrically compatible (3.3V/5V) and that the card’s drivers support the host operating system. Use the included bracket that matches your chassis form factor and secure all connections before powering the system. For industrial or embedded deployments, confirm mechanical clearance and system airflow when adding the adapter and PCI card.
