PCIe Expansion Chassis 4‑Slot StarTech 4PCIE‑PCIE‑ENCLOSURE, PCIe 2.0 x2 Host (USB‑C), 4 × PCIe x1, 10 Gbps, 12V 3A, ASMedia ASM1806

StarTech PCIe Expansion Chassis 4‑Slot (4PCIE‑PCIE‑ENCLOSURE) is an external enclosure that provides four PCIe x1 slots for desktops and servers. It uses an ASMedia ASM1806 chipset and connects to the host via a PCIe 2.0 x2 host card that interfaces over a screw‑lock USB‑C cable, delivering up to 10 Gbps total bandwidth. The steel housing and vented design enable passive cooling and deployment in environments with an operating temperature range of 0° to 60°C (32° to 140°F).

Advantages

The chassis supports Wake‑on‑LAN (WoL), PCI Express Advanced Error Reporting (AER) and EndPoint Cyclic Redundancy Check (ECRC) for improved PCIe link reliability. It is operating system independent and requires no enclosure drivers; expansion cards installed inside may still need their own drivers. The enclosure includes a low‑profile bracket for small form factor compatibility and a screw‑lock USB‑C cable for a secure connection. Multiple power input options (USB‑C host power, 12V DC adapter, or 12–24V via terminal block) add installation flexibility.

Suitable for

• Adding Ethernet, fiber, USB, serial, or parallel PCIe cards to systems without internal slots
• Testing or swapping expansion cards between multiple computers or operating systems
• Expanding I/O capabilities of desktops, small form factor PCs, or servers

How to use

Install the included PCIe 2.0 x2 host card into the host computer (use the low‑profile bracket if installing in a small form factor system). Connect the host card to the expansion chassis using the supplied screw‑lock USB‑C cable. Mount desired PCIe x1 cards into the enclosure and secure them. Choose the appropriate power source: allow power through the USB‑C host connection if supported, connect the 12V 3A DC adapter, or supply 12–24VDC via the terminal block. After connections are made, power on the host and the enclosure; install any drivers required by the individual expansion cards.

Usage recommendations

For reliable operation, use the supplied screw‑lock USB‑C cable and secure the enclosure with the included mounting brackets. Verify card driver compatibility with your operating system before installation and ensure the chosen power input meets the combined power requirements of installed cards.
