What the product is

The StarTech PEX2PCI4 is a PCI Express to PCI expansion chassis that adds four external 32-bit 33 MHz PCI slots to a desktop or laptop through a single PCIe x1 connection. It delivers up to 250 MBps of total bandwidth so the host treats the installed cards as if they were on the motherboard.

Who this suits and who should look elsewhere

This suits technicians who need to connect legacy PCI cards to modern systems without internal slots, or mobile users swapping add-in cards between a laptop and a desktop. It is not for buyers who need more than four slots, higher bus bandwidth, or internal mounting inside the host chassis.

The specification that decides fit

The chassis provides exactly four 32-bit 33 MHz PCI slots fed by a PCIe x1 link with 250 MBps aggregate throughput. If your cards require more bandwidth or a different slot count, this unit will not meet the requirement.
