Setup

Step 1 — Connect power: Plug the included 180W power supply into the DC port (Port 6) on the back of the dock, then plug the power supply into a wall outlet.
Step 2 — Connect to host: Use the included Thunderbolt 5 cable to connect the Thunderbolt 5 Host Port (Port 11) on the back of the dock to a Thunderbolt 5 port on your computer.
Step 3 — Power on: Press the Power Button (Port 1) on the front of the dock. The white LED will illuminate to confirm the dock is powered and active.
Step 4 — Connect devices: Plug your peripherals, drives, and displays into the appropriate ports. No drivers are required on macOS. Windows may require driver installation for full functionality.

Display Output Support

The three Thunderbolt 5 downstream ports (Port 12) support the following display configurations:

Single display: Up to 8K/144Hz (Windows) · Up to 6K/60Hz (macOS)
Dual display: Up to 8K/120Hz each (Windows) · Up to 6K/60Hz each (macOS)
Triple display: Up to 8K/60Hz each (Windows only) · Triple display not supported on macOS

SSD Installation

The M.2 NVMe SSD Enclosure (Port 13) on the side of the dock accepts M.2 M-Key NVMe SSDs in 2230, 2242, 2260, and 2280 form factors. SATA SSDs are not compatible.

For detailed SSD installation steps, scan the QR code on page 8 of the included User Manual PDF, or refer to the SSD Installation article in the Satechi Help Center.

Important Notes

Requires a Thunderbolt 5 host computer: The dock must be connected to a Thunderbolt 5 port to achieve full Thunderbolt 5 speeds. It is compatible with Thunderbolt 4, USB4, and USB-C hosts at lower bandwidth.

White LED blinking indicates a fan issue: If the Power Button LED blinks white, the internal fan may be disconnected or stuck. Power off the dock and contact Satechi Support.

Triple display not supported on macOS: Due to macOS limitations, only one or two external displays are supported simultaneously. Triple display requires a Windows host.

SATA SSDs are not supported: The M.2 SSD enclosure is compatible with NVMe (M-Key) SSDs only. SATA SSDs will not function in this slot.

Frequently Asked Questions

A blinking white LED indicates the internal fan is disconnected or stuck. Power off the dock and contact Satechi Support at support.satechi.com.

How many displays can I connect?
On Windows, up to three displays at up to 8K/60Hz each. On macOS, up to two displays at up to 6K/60Hz each. Triple display is not supported on macOS.

What SSD types are compatible with the enclosure?
The enclosure supports M.2 M-Key NVMe SSDs in 2230, 2242, 2260, and 2280 form factors. SATA SSDs are not supported. Maximum capacity is 8TB.

How much power does the dock deliver to my laptop?
The Thunderbolt 5 host port (Port 11) delivers up to 140W to the connected host computer.

Does this work with Thunderbolt 4 or USB-C computers?
Yes. The dock is backward compatible with Thunderbolt 4, USB4, and USB-C hosts, though at reduced bandwidth compared to a Thunderbolt 5 host.
