Safety Instructions
Always use caution when servicing any electrical component. Before handling the expansion chassis, read the following instructions and safety
guidelines to prevent damage to the product and to ensure your own personal safety. Refer to the “Advisories” section for advisory
conventions used in this manual, including the distinction between Danger, Warning, Caution, Important, and Note.
Always use caution when handling/operating the computer. Only qualified, experienced, authorized electronics personnel should
access the interior of the computer and expansion chassis per UL and IEC 60950-1
The power supplies produce high voltages and energy hazards, which can cause bodily harm.
Use extreme caution when installing or removing components. Refer to the installation instructions in this manual for precautions
and procedures. If you have any questions, please contact Technical Support.
WARNING
Never modify or remove the radio frequency interference shielding from your workstation or expansion unit. To do so may
cause your installation to produce emissions that could interfere with other electronic equipment in the area of your
system.
When Working Inside a Computer
1. Before taking covers off a computer, perform the following steps:
2. Turn off the computer and any peripheral devices.
3. Disconnect the computer and peripheral power cords from their AC outlets or inlets in order to prevent electric shock or system
board damage.
In addition, take note of these safety guidelines when appropriate:
To help avoid possible damage to systems boards, wait five seconds after turning off the computer before removing a component,
removing a system board, or disconnecting a peripheral device from the computer.
When you disconnect a cable, pull on its connector or on its strain-relief loop, not on the cable itself. Some cables have a connector
with locking tabs. If you are disconnecting this type of cable, press in on the locking tabs before disconnecting the cable. As you pull
connectors apart, keep them evenly aligned to avoid bending any connector pins. Also, before connecting a cable, make sure both
connectors are correctly oriented and aligned.
CAUTION
Do not attempt to service the system yourself except as explained in this manual. Follow installation
instructions closely.

Protecting Against Electrostatic Discharge
Electrostatic Discharge (ESD) Warning
Electrostatic Discharge (ESD) is the enemy of semiconductor devices. You should always take precautions to eliminate any
electrostatic charge from your body and clothing before touching any semiconductor device or card by using an
electrostatic wrist strap and/or rubber mat.
Static electricity can harm system boards. Perform service at an ESD workstation and follow proper ESD procedures to reduce the risk of
damage to components. We strongly encourage you to follow proper ESD procedures, which can include wrist straps and smocks, when
servicing equipment.
You can also take the following steps to prevent damage from electrostatic discharge (ESD):
When unpacking a static-sensitive component from its shipping carton, do not remove the component’s anti-static packaging
material until you are ready to install the component in a computer. Just before unwrapping the anti-static packaging, be sure you
are at an ESD workstation or are grounded.
When transporting a sensitive component, first place it in an anti-static container or packaging.
Handle all sensitive components at an ESD workstation. If possible, use anti-static floor pads and workbench pads.
Handle components and boards with care. Do not touch the components or contacts on a board. Hold a board by its edges or by its
metal mounting bracket.

1 Introduction
ExpressBox 3T-eGPU provides an 'outside-the-box' solution for housing an external graphics card. Connected to Thunderbolt-equipped
computer via Thunderbolt3. High-performance work flows are possible by connecting a Thunderbolt equipped computer to an ExpressBox 3T-
eGPU containing GPU card. Designed for professional applications, 3D gaming, VR content creation, video capture, rendering, media transcoding,
audio processing, scientific calculations and algorithms.
EB3T-V3-eGPU as external graphics (eGFX) solutions boost graphics capability of any portable thunderbolt-equipped notebooks and
computers. It allow smaller thunderbolt-equipped computers to benefit from the power of a full-sized graphics card via a high-speed bandwidth
connection. Thunderbolt 3 is capable of transmitting at a rate of 40Gbps (maximum speed), which is faster than a USB 3.1 rate of 10 Gbps or
USB 3.0 of 5Gpbs.
EB3T-V3-eGPU uses Thunderbolt3 - USB Type-C 3.1 thin cable / connector. The EB3T-V3-EGPU connects to Thunderbolt 3 port and USB Type-C
ports. The Thunderbolt 3 cable provides four times the data and twice the video bandwidth while also supplying power.
PCI Express Features
Supports one full-length card
One PCIe 3.0 x16 slot (x16 Electrical / x16 Mechanical / Thunderbolt3 Spec).
Slot 0 is the upstream slot; it is x16 lane connector, Gen3. Thunderbolt 3 card is only x4 lane. The upstream slot will operate at x4
lane Gen 3.
EB3T-V3-eGPU Features
High-speed Thunderbolt connection –Thunderbolt 3 40 Gbps.
o4 lanes of PCI Express Gen 3
Automatic power-up control by computer
One PCIe (x16) slot supporting full-length, full height, double-width card.
Accommodate standard and large sized graphics card.
Built-in 400W power supply to provided extra power to GPU.
PCIe x16 slot provides up to 75W of power.
Adjustable Fan-Speed Control.
Movable 8x8 cm fan cooler at enclosure's side.
15W power delivery to the host computer.
