PCIe x1 to PCI Slot Adapter

The StarTech PEX1PCI1 adapter card lets you install half-height PCI interface cards into a standard PCI Express x1 expansion slot. It bridges legacy PCI peripherals to modern motherboards that no longer provide native PCI connectivity.

Builders migrating older PCI cards

This adapter suits technicians and hobbyists who need to keep using specialised PCI sound cards, network adapters or I/O controllers on newer platforms. It will not help users whose expansion cards require a full-height bracket or a different electrical interface than the one specified.

PCI Express to PCI Bridge spec 1.0

The card complies with the PCI Express to PCI/PCI-X Bridge specification 1.0 and PCI Local Bus specification 2.2. Verifying that the target PCI card operates within these bridge parameters is the single check that decides whether the adapter will work.

Questions about this item

How do I install the PEX1PCI1 adapter in a PCI Express slot?

Insert the card into an available PCI Express x1 slot, secure the bracket, and connect the LP4 power connector to supply power to the installed PCI card.

What maintenance will the PEX1PCI1 require over time?

No routine maintenance is required; ensure the LP4 power connector remains firmly seated and keep the slot free of dust for reliable operation.

What limits sustained throughput on the PEX1PCI1?

The PCI Express x1 link and PCI Local Bus 2.2 specification cap bandwidth, so sustained transfers cannot exceed the x1 lane and 2.2 bus limits.
