Thelio Major is a high-end desktop designed with an all-star roster of components that breeze through intensive computing. We take this power even further by engineering the desktop to ensure it performs to its fullest potential.


Eager Processors

High-end processor AMD Threadripper 7980X works to see your project completed as quickly as possible. With up to 64 CPU cores and 128 threads, Thelio Major drastically reduces wait times when processing your final file—no matter how many “final” versions

Countless Cores

The more GPU cores in your desktop, the faster your project can be visualized. Thelio Major offers full-core performance with up to an NVIDIA RTX 6000 ada GPU so you can model, simulate, and animate your work in record time.

Compile and Render Fast

Thelio Major is configurable with up to 512GB of ECC DDR5 memory. If you’re frequently rendering visualizations or compiling long sequences of code, more memory will greatly accelerate your project’s timeline.


This is what Thelio Major was built for: fast AI development backed by high-end NVIDIA graphics, a workhorse CPU, and divide-and-conquer thermals sustain unstoppable progress. Model, train, and simulate AI, and secure a brighter future for humanity.

Thelio Major is meticulously engineered to maximize performance and prevent throttling.


Optimized Ducted Cooling

After countless iterations testing fan placement, CPU duct size, exhaust port design, and other factors, we landed on the most optimal arrangement for effective cooling at low decibels. For large GPUs, an optional side intake fan increases airflow to maintain lower temperatures.

Game in Luxury

Thanks to thermal engineering and a progressive fan curve, the heat generated by your graphics card exhausts effectively without causing your system unnecessary stress—leaving you to enjoy all the latest graphical perks. Thelio Major leaves room for some of the largest GPUs on the market, so the side intake fan add-on is highly recommended for keeping your system cool.

Controlled Thermal Environment

Chassis-specific thermal engineering yields quiet and effective cooling in perfect balance. The Thelio IO board allows your operating system to monitor the temperature of your GPUs and adjust fan speeds for intensive computing. Large 140mm fans move air more effectively at a lower RPM, producing quieter acoustics. In short, Thelio Major is designed to prevent throttling and run efficiently at every level.


Thelio desktops are designed to provide easy access to your motherboard for upgrades and repairs. Slip in drives, add memory, and upgrade graphics cards at will with our open hardware design.


Side Panel Access

Unscrew the lid and access everything in the system. No obstructive wires, no loose parts.

Room (and Wires) for Upgrades

Any wires you’ll ever need are already provided inside the system to accommodate upgrades. Thelio Major prevents throttling of the largest, most powerful GPUs on the market using a recommended side intake fan add-on.

Easy Storage Expansion

The screw bay on the top bar houses enough screws to install the maximum number of 2.5” storage SSDs. Hot swappable drives slide in and out of the aluminum drive cage with ease.

Swappable accent colors

Let your alter ego shine with swappable color accent panels on Thelio Major! Ponder with Neptune Blue, or use Martian Red to rise to the challenge. And when the day is done, Farout Pink will help you blow off steam on Steam.



Rigid aluminum is cut, powder coated, and molded into a light, durable chassis. From the Solar System exhaust port to the arcade-style power button, Thelio Major adds elegance and character to your desk.
