Designed with 100% Japanese capacitors and boasting an 80-Plus Gold efficiency rating, it supplies stable, continuous current to your GPU while effortlessly handling sudden power spikes during heavy gaming or rendering sessions.
Space-Saving Desktop Design with Integrated Laptop Stand Dock
De-clutter your studio workspace with functional, ergonomic styling. The MasterCase EG200 features a unique, built-in **vertical laptop storage slot** directly on its side panel. This anti-scratch, rubberized dock securely holds your closed laptop upright when connected to external monitors, maximizing available desk space while promoting clean passive cooling airflow across both hardware systems.
Intelligent USB Hub Pass-Through & SATA Drive Expansion
Convert a single cable into an entire workstation docking array. The rear I/O matrix expands your laptop's accessibility with a built-in **3-port USB 3.0 Type-A hub**, a dedicated USB Type-B control path, and an **internal 2.5-inch/3.5-inch SATA hard drive bay**. Easily slide in an extra solid-state drive (SSD) or high-capacity hard drive (HDD) to host massive game libraries or media cache files without needing extra external enclosures.
Targeted Hot-Air Exhaust Component Cooling
Maintain thermal stability under high seasonal ambient temperatures. The structural steel casing features optimized ventilation paths along the side, top, and rear frames. Driven by an automated, pre-installed **120mm temperature-controlled exhaust fan**, it rapidly draws hot air out from your graphics card's cooling system, keeping internal hardware safely within peak performance temperatures.

DESKTOP PERFORMANCE FOR YOUR LAPTOP
Boost the performance of your laptop to a desktop gaming PC or workstation with the EG200.
The EGPU allows the installation of a desktop PCIe graphics card via the ultra high-bandwidth Thunderbolt™ 3 interface, allowing you to increase the GPU performance of any Thunderbolt™ 3 equipped PC or Mac.
Further expand the usability of your laptop with a dedicated USB hub I/O, hard drive and SSD dock, and a convenient vertical laptop stand.
GREATLY BOOST GPU PERFORMANCE
Add the power of a desktop graphics card to your laptop.
The EG200 interfaces to a laptop with a high-bandwidth Thunderbolt™ 3 connection to greatly increase gaming performance or compute performance with a dedicated graphics card.
THUNDERBOLT(TM) 3 CONNECTION
The Thunderbolt™ 3 connection supports a blistering speed of up to 40Gbit/s and 60W laptop charging via the USB-C. The EG200 is outfitted with the latest JHL7440 controller to ensure maximum performance and compatibility.
BUILT-IN LAPTOP STAND
Neatly dock your laptop into the space-saving built-in vertical laptop stand and work from directly from an external monitor like a desktop.
DEDICATED I/O PORTS
The dedicated USB connection separates the USB hub functionality from the Thunderbolt™ 3 connection to allow the graphics card or other PCI-e device use of the maximum Thunderbolt™ 3 bandwidth.
HARD DRIVE DOCK
Expand the limited storage on your laptop with an added 3.5" or 2.5" HDD/SSD drive for your game library or project files.
SPACE-SAVING COMPACTNESS
At just 9.7L the EG200 is one of the smallest e-GPUs on the market supporting full size cards while saving valuable desktop space.
HIGH COMPONENT COMPATIBILITY
With an included 550Watt PSU, the EG200 can support even the most power-hungry graphics cards on the market. Cards with dimensions up to 325 x 54 x 141mm are supported.
Also compatible with any other PCI-e add-in card such as gigabit ethernet, NVME expansion cards, etc.
ADAPTIVE THERMALS
EG200 comes with a built-in temperature sensor. Similar to graphics cards, this allows fans to remain idle under light loads. Should internal case temperatures reach 45°C under heavy load, the fan will activate and ramp up relative to the temperature, keeping your system quiet, yet cool when needed.
