The StarTech.com PCIe expansion chassis is designed to add external PCIe x1 slots to desktops or servers with limited internal expansion options. It provides a way to install additional cards such as USB, Ethernet, SFP, or serial cards without requiring internal space. The chassis connects via a proprietary PCIe x2 host card and a locking USB-C cable, making it ideal for environments where space is limited or where external expansion is needed.
The expansion box features a rugged SECC steel construction that can withstand high temperatures up to 140°F (60°C) and includes a vented design for passive cooling. This ensures quiet operation even in demanding environments. The chassis includes a power adapter, terminal block port, and mounting brackets for secure installation. It supports multiple power options, including through the host card, a 12V 3A DC adapter, or a terminal block port that accepts 12-24VDC.
This expansion chassis is compatible with Windows, macOS, and Linux operating systems and does not require any additional drivers for the chassis itself. However, installed add-on cards may need their own drivers and specific OS support. It supports advanced PCIe features like Wake-on-LAN (WoL), PCI Express Advanced Error Reporting (AER), and EndPoint Cyclic Redundancy Check (ECRC), which help maintain stable connections between devices.
The included 5.9ft (1.8m) locking USB-C cable ensures secure connectivity between the host system and the expansion box. A low-profile bracket allows the host card to fit into small form factor systems. The expansion box is ideal for testing hardware across different systems or upgrading I/O capabilities without replacing the entire host system. It is not intended for use with GPUs due to its design and bandwidth limitations.
