The combination of metal and aluminum sheets played out well and the rubber feet does a good job of making sure the eGPU sits well on a flat surface. It looks polished and would surely make your setup look better.

The enclosure work well with both medium and large sized graphics card. it supports both NVIDIA and AMD based GPUs. if you decide to buy the Breakaway Box 750 it will last for at least five years or more because you can be able to switch the graphics cards inside the enclosure. Whenever you feel the graphics card inside the enclosure is not as fast as you want you have the option to switch to a faster one.

Cross Platform

the Breakaway Box 750 supports both windows and macOS and this will be very useful for people that use both MacBook’s and Windows laptops. you can decide to keep the enclosure for both operating systems. This feature will save you money because there are some enclosures out there that work for only MacOS. Originally the eGPU technology was created to bolster the performance of MacBook’s but over the years window laptops have also benefited from the technology.

Extra Ports

The enclosure has some ports that can be used to connect some peripherals. These ports are not available on the Breakaway Box 750 and they are useful. The ethernet ports will allow you connect the enclosure to the internet easily. We also have some USB type A ports and they are very important as well. The extra ports are the only feature that separates the two enclosures from one another.

Power Delivery

the enclosure is going to charge your laptop while in use because it supports 100W power delivery. This means you can charge your laptop through the thunderbolt port when connected to the enclosure. 100W is enough to charge any laptop decently be it MacBook or a windows laptop.

750 Watts Power Support

The eGPU has the capacity to power even the most demanding graphics card 750 watts has the capacity to power even the AMD Radeon VII. This also adds to the enclosure being future proof because it can support various types of graphics cards.

A Closer Look at the Sonnet eGPU Breakaway Box 750ex

To open the enclosure, you need to unscrew three screws at the back of the enclosure. Opening it up is not as easy as we have with other enclosures. There is no rail system that makes everything easy to pull from the back or front. The box is big enough and it can house graphics cards from Radeon, AMD, or NVIDIA. Apple MacBook’s doesn’t support NVIDIA graphics card so it is important to know this when buying the enclosure for your MacBook. You can find a list of compatible GPUs in various forums like reddit or depending on the graphics card you decide too use you are going to get additional ports through the PCIe expansion box. As a content creator the enclosure when paired with the right graphics card would significantly improve your work flow. The extra ports you get make it a little bit versatile than the breakaway box 750. You can swap various graphics cards inside the enclosure which makes the enclosure future proof. You can use it for years and it will still deliver consistent performance because it has the power to match various graphic cards. eGPU is also priced reasonably well and it has what it takes to compete with the Razer Core X.

Description of Sonnet eGPU Breakaway Box 750ex

Nothing impacts gaming, videos, or graphic-intensive applications as much as a dedicated graphics card. Today’s all-in-one and notebook computers may be sleek and thin, but their modern designs with integrated GPUs comes with the lack of high-performance graphics.

Pros of the Sonnet eGPU Breakaway Box 750ex

Highly Versatile – the enclosure supports various types of graphics cards making it versatile and future proof. You can use different brands of GPUs like NVIDIA, AMD, and Radeon graphics cards inside the enclosure and they will work just fine. It supports medium to large graphics card options and it can even take up power hungry graphic cards.

Premium Build Quality – the materials used to construct the enclosure are of high quality and we have a combination of metal and anodized aluminum. It is not very big and it will surely beautify your desk if you place it there. Sonnet paid attention to every detail why building the enclosure and the feet at the bottom make sure it stands on a flat surface and it doesn’t wobble.

Power Delivery – the enclosure has 100W power delivery and it will charge any type of MacBook or windows laptop when connected through thunderbolt 3. 100 watts is sufficient enough to charge any type of laptop. this feature is very important because it will save you from connecting to many cables to your laptop at the same time.

Extra Ports – we have extra ports on the Breakaway Box 750ex and they are very important. That is the only physical difference between the Breakaway Box 750 and the Breakaway Box 750ex. The ports on the enclosure will allow you connect more peripherals to the enclosure. There is also an ethernet port that will allow you connect the enclosure to your network easily.

Cons of the Sonnet eGPU Breakaway Box 750ex

Difficult to open – I find this to be a problem because you can’t just take off the cover easily or slide open like you do with other external enclosures. You have to struggle after taking off the screws at the back of the enclosure. Other enclosure come with a rail mechanism that makes them easy to open.


Does this come with a Graphics card?

No, it doesn’t come with a graphics card you have to shop for the graphics card separately after buying the eGPU. This is one of the reasons why people are yet to fully accept the eGPU technology. You end up spending what will build a working PC for a tiny box.

Is it compatible with macOS?

Yes, it works on macOS but NVIDIA graphics cards doesn’t run on MacOS you need to buy other brands of GPU if you want to use the enclosure on macOS.

What is the maximum size of Graphics Card that will fit inside the enclosure?

The maximum card that will fit inside the enclosure chassis is 312mm x 160mm x 55mm some NVIDIA, AMD and Radeon cards fit this description perfectly.

Rounding Up

If you need the ports that the Breakaway Box 750 doesn’t come with then the Breakaway Box 750ex can be fine substitute. But then you have to spend $60 more to get the 750ex the only difference between the two is the availability of ports on the 750ex. Otherwise they are the same in every aspect. When paired with the right GPU it has the capacity to improve the performance of your laptop.
