STARTECH 4PCIE-PCIE-ENCLOSURE server chassis

4-slot PCIe expansion chassis

This 4-slot PCIe expansion chassis adds four full-size PCI Express slots to a host system through a single upstream link. It targets workstation users who need additional add-in cards such as capture, networking or compute accelerators but have no free slots inside the host enclosure. The unit ships as a complete external chassis with an integrated power supply.

Tool-less card installation

Cards slide into the chassis without tools and lock with the standard retention bracket. The only common friction point is the upstream host connection: the host must provide a compatible PCIe link and the cable must be seated firmly, otherwise the additional slots will not enumerate. No driver is required for the chassis itself; only the installed cards need software.

Active cooling sustains multi-card workloads

Built-in fans draw air across all four slots continuously, so temperatures remain stable when multiple cards run at full bandwidth for extended periods. The included power supply is sized for the chassis and typical add-in cards, delivering steady voltage without the throttling seen in short-burst tests. Acoustic output rises with sustained load but stays within typical workstation limits.
