Product Description

SONNET eGFX Breakaway Box 550 TB3 External Graphics Enclosure

Upgrade without throwing out

As laptops and desktops become ever increasing in their upgrade cycles, sometimes a machine from a couple years ago is just fine on the CPU front and the bottleneck generates from the graphics card becoming out of date. The Sonnet eGFX Breakaway Box is the perfect solution to upgrading a recent laptop like a Macbook Pro or one of our lower end 3XS system machines and even circumvent the cycle of buying everything new again.

Full Sized Graphics Card on the go

The eGFX Breakaway Box comes outfitted with a Thunderbolt 3 port, making it ideal for connecting to the latest laptops and interfaces. The PCI-e (PCI Express) port inside and the unit itself can fit a full length graphics card, like the best in the world at the moment, the NVIDIA GTX 1080ti and AMD Vega 64. For those more production inclined, the Breakaway Box also supports the Quadro line of cards.


Having the ability to circumvent the need to buy a whole new system gives life to machines that still have the speed and power elsewhere, but might not be able to hold their own in the graphics department. The Sonnet eGFX Breakaway Box gives you options that weren't previously available. Once you're ready to fully upgrade to a new system entirely, you can bring the full card into your machine.

Thunderbolt 3

The power of Thunderbolt 3 means that external graphics card expansions are now actually usable. In the past, with USB 2.0, 3.0 or Thunderbolt 2, the speed just wasn't there, but the sheer power of this advancement means that the full blown power of the graphics card can be implemented.
