Selecting the Best eGPU for your laptop

Sonnet have a similar identity when it comes to their enclosures and the Breakaway Box 550W is does not separate itself. It has a similar look like the Breakaway Box 750 and 750ex the only real difference is the power capability and the Breakaway Box 550W only supports 550 watts power. If you decide to buy the breakaway Box 550w ahead of its successors then power supply will be one of the compromises you will settle on. Even at that 550w is enough to power majority of the GPUs out there one of the most popular enclosures which is the Razer Core X maxes out at 500 watts. The enclosure is made for avid laptop gamers that don’t see the need of playing games on a desktop. through the thunderbolt 3 port it is able to transfer data at 40Gbps and it has what it takes to increase the frame rates of your laptop while gaming. There is a fan inside the enclosure and it is accompanied by a PSU they function as thermals inside the enclosure keeping it cool when in use. the power system is custom made and we have a 24-pin main power cable, one 6-pin PCIe cable, and one 6-pin + 2 PCIe cable. The enclosure does well when dealing with noise while in work mode even when you have a powerful graphics card inside the enclosure the noise is still low. At the heart of the enclosure we have the main board for the thunderbolt 3. The build of the enclosure is different from that of the Akitio Node that we talked about earlier. The enclosure is sturdy and it was beautifully crafted using a high-quality metal that we talk more about in a bit. Sonnet has different versions of the Breakaway Box and they are differentiated by the number at the end. There might be little extras depending on the box you have.

Here are 6 key points for selecting the Sonnet eGFX Breakaway Box 550W for your laptop

Thunderbolt 3 Connectivity

The first and major reason why you should buy the Sonnet eGFX enclosure is because it has a thunderbolt 3 port. without the port the enclosure would be useless because it cannot enhance the performance of your laptop. the technology was originally created to help boost the performance of intel-based MacBook’s. if your laptop doesn’t have a thunderbolt 3 or 4 port then there is no point in buying the external enclosure at the moment that is the only connectivity supported. It transfers data from the GPU extension box to your laptop at 40Gbps and that is the maximum speed.

Supports Both Windows and MacOS

The Breakaway Box 550W was one of the earliest eGFX that supported windows laptops. initially eGPU technology was originally made for MacBook users to benefit from the advantages of a GPU. It works fine on both windows and MacBook’s. however, MacBook’s are selective when it comes to GPU and they are not compatible with NVIDIA GPUs at the moment. you can use a wide range of AMD graphics card inside the enclosure.

Power Delivery

The enclosure has 87W power support for charging your laptop while it is connected to your laptop. you don’t need to connect a lot of cables because thunderbolt 3 can charge your laptop when connected to any enclosure with Power Delivery. This feature helps with cable management and also keeps your laptop charged.

Future Proof

The ability to swap out graphics cards make this enclosure future proof and you can use number of different GPUs. you can select from a wide range of cards and insert inside the enclosure. It sometimes depends on the operating system you are using. You can also use PCIe cards inside the enclosure If you want to. It also has 550 watts power support meaning it can power most of the graphics card that are available out there. The enclosure can last between 4 to five years if you decide to buy it.

Solid Build Quality

The enclosure has a solid build quality it looks premium in every angle and Sonnet did a good job in constructing the enclosure. 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 in every aspect. The only thing I think that sonnet didn’t pay attention to is the opening mechanism.

550 watts Power Supply

The enclosure has a reasonable power supply at 550W and it can power some top-rated graphics cards. The power supply mechanism is also great and we have 6 + 2 Pin power connectors inside the enclosure that takes power to the GPU.

A Closer Look at the Sonnet eGFX Breakaway Box 550W

Inside the box of the enclosure you will find the Breakaway Box 550W, a power cable, 0.5-meter thunderbolt 3 USB type C cable, and documentation. We have a metal build here and the front is made of a matte plastic material and it doesn’t catch up stains and dirt. The Sonnet logo up front shows light when the eGFX is powered on. It is amazing to see that the enclosure can take up various sizes of GPU. I don’t have the specific dimensions that can fit inside the box but you will find more information regarding the types of GPUs that works well on platforms like reddit. Some cards that I am sure work well inside the enclosure includes the RX 580, 570, and 480 cards It weighs 11.46 pounds and that is quite heavy for an enclosure. Installing a graphics card is easy all you need to do is to open the box by removing the three screws at the back. opening up the box is not as easy there is usually a little bit of struggle to take the cover apart. One thing to note is that after hours of use the box tends to get hot but it is nothing to worry about. The thunderbolt 3 port is located at the back of the enclosure we also have the power switch at the back.

It has a number of important ports that can be used to connect to monitors and other peripherals. We have two thunderbolt 3 ports on the enclosure. It is capable 6K resolution display on a single monitor that supports thunderbolt 3. You can also connect 3 displays at the same time if they support thunderbolt 3. It has a small compact form factor and it can be hidden behind a monitor.

Pros of the Sonnet eGFX Breakaway Box 550W

Less Noise – the thermals of the enclosure keep it dead silent when idle and even if you use a powerful graphics card inside it doesn’t make a loud noise. we have a fan inside the enclosure that keeps the enclosure cool and we also have a PSU to complete the thermals. It is not as loud as Akitio Node and the fans doesn’t vibrate when in use.

Supports Different GPUs – the enclosure has the power support and ability to work with various types of graphics cards. It works with AMD, NVIDIA, and Radeon graphics cards and it works just fine. you can also decide to use PCIe cards inside the enclosure and it will work perfectly. It has 550 watts power support and it can be paired with some of the most powerful graphics cards.

Power Delivery – you can use the 87 watts power delivery support to charge your laptop while its connected to the enclosure through the thunderbolt 3 port. with power delivery you don’t have to connect your laptops charging cable while your MacBook is connected to the Breakaway Box 550W.

Cross Platform – this is one of the first external graphics card that officially supported MacBook’s and windows laptops. it works well on both operating system but it doesn’t support running windows through bootcamp. MacBook’s don’t work on the enclosure when paired with an NVIDIA video card.

Cons of the Sonnet eGFX Breakaway Box 550W

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.

Short Thunderbolt Cable – the cable bundled inside the box is 0.5 meter and I find it to be short. If you want a better thunderbolt 3 cable you need to buy it separately. There are a lot of high-quality thunderbolt 3 USB type C cables available on Amazon.

Looks Big – the enclosure is big and it is easily going to be noticed when placed on a desk. It is no where near the size of the Breakaway Puck that can even be hidden at the back of a monitor. It is aesthetically pleasing because of the design but it takes up space on a desk. 

F.A.Q

Does it come with a GPU?

No, you are only getting the enclosure at $250 and you have to shop for the graphics card separately.

Can it be used to read PCIe SSD cards?

The enclosure will work with any thunderbolt 3 compatible PCIe card that can fit inside.

Does it work with laptops that have thunderbolt 2?

No, it doesn’t you need a thunderbolt 3 or two on your laptop for the enclosure to work. Thunderbolt 2 doesn’t have the power needed to transfer the data required to boost the performance of a laptop.

Rounding Up

The Sonnet eGFX Breakaway Box is one value for money enclosure that supports various types of graphics cards. It has a 550W power supply and the capacity to turn your laptop into a powerful machine. Your laptop will not only run graphic demanding games but it will also be able to run some intensive software’s. although it lacks some features like versatile ports and I/O it still one of the cheapest eGPU out there that can serve well. Sonnet however needs to find a better way of differentiating their enclosure rather than sticking with their current style of using the power support capacity in the name.
