Description

1 – Power Indicator LED

This lights up when the eGPU Breakaway Box is connected
to a power source and the power switch turned on, the
Thunderbolt cable between the chassis and your computer is
plugged in, and the computer powered on.

2 – PCIe Card Bracket Mounting Screws/Locking Plate

These secure the installed PCIe card in place.

3 – Port Access Cover

This covers the opening in the chassis when a single-width
card is installed.

4 – Power Switch

5 – Power Input Socket

Connect the included AC power cable here.

6 – Thunderbolt Port

Connect the included Thunderbolt cable, or comparable
Thunderbolt 3 (40Gbps) cable, between either port and your
computer’s Thunderbolt port.

7 – Gigabit Ethernet Port (only on 750ex model)

Plug in a Cat 5 or Cat 6 unshielded twisted pair (UTP) cable
with RJ45 connectors. The left LED flashes yellow to indicate
activity, while the right LED lights up orange to indicate a
1000BASE-T (Gigabit) link or green for a 100BASE-TX link,
and remains off for 10BASE-T.

8 – USB-A Ports (only on 750ex model)

Connect USB devices to these ports.

9 – Main Fan

This provides cooling for the installed PCIe card and the
chassis’ supporting Thunderbolt circuitry. It operates at a
whisper when the card is running cool, and automatically
speeds up in steps as the temperature rises. Do not block the
fans or the vent holes on the chassis to prevent overheating.

10 – Power Supply

The power supply has its own fan that operates independently
from the main fan.

11 – PCIe Card Slot
