Why you need the Highpoint RocketStore 6661A for your laptop

Using a laptop without a GPU is a difficult task especially when you are into gaming or content creation like photo or video editing. A laptop that doesn’t have a GPU is only suitable for doing basic task and playing 3D games. It is not fast enough and if you start running intensive games and software’s on a laptop without GPU it will always crash.

If you care about speed then you won’t go after a laptop without a GPU. These types of laptops are only suitable for commercial and office works. Sometimes people often buy laptops with high-end specs and after a number of years the parts become outdated and worn out.

That’s where the highpoint rocketstore 6661A comes in and it can help boost the performance of your old laptop. if your laptop has a thunderbolt 3 port then an external graphics card can be used to increase the performce of your laptop. it will allow new and updated games run smoothly on your old laptop.

The eGPU technology is still in its early stages and it already works fine with most laptops. Most people like the comfort of moving their laptops around and with an eGPU you can plug in and run your task.

You can unplug your laptop when you are done and move it where ever you want to. You need the highpoint rocketstore 6661A because it will power your laptop if you pair it with a very strong GPU.

Selecting the Best eGPU for your Laptop

The external enclosure has a metal build with a slip off cover secured by a captive thumbscrew. It is wide enough for normal sized PCIe to fit in its x16 PCIe lanes slot. The slot is just like the ones you will find on a desktop PC. The card is held with a screw from the upper part of the end bracket.

When it comes to look the enclosure us not glittering but when it comes to performance it is top notch. It comes covered in a matte aluminum finish with an array of opening to circulate air drawn by the two small fans. Cooling here is great because of the openings and fans.

At the back of the enclosure we have two thunderbolts 3 ports and an AC power jack. there is no dedicated display port on the enclosure and that is one of the shortcomings of the eGPU. The second Thunderbolt 3 port on the enclosure can be used as an extension to add in a display port and other peripherals.

There is no on and off switch and this reminds me of the Sonnet Echo SE1 enclosure it has similar features. The enclosure has plug and play feature as it senses power when the RocketStore 6661A is connected to a laptop. the eGPU works well with MacBooks that have a thunderbolt port.

It stands perfectly on any flat surface and the tiny feet at the bottom that hold the enclosure. I like the design of the enclosure it is solid and unique but it lacks some features that might be a knockoff for some people.

6 key points for selecting the Highpoint RocketStore 6661A for your laptop

Two thunderbolt 3 ports

The enclosure has two thunderbolt ports and it is one of the few PCle extension boxes that comes with the feature. The second port can be used to attach peripherals and the main port guarantees the maximum 40Gbps when transferring data from the enclosure to your laptop.

Compact Build

The enclosure has a unique looking design that sets it apart from other eGPU that house PCle cards. Its stands on its feet and will instantly fit in any setup because it doesn’t take up much space. it has a metal build with vents all over the enclosure. Opening it up is very easy and there are two fans inside the box that dissipate air when in use.

Plug and Play

The enclosure doesn’t have a power button so the moment you plug it into your laptop via the thunderbolt 3 port it starts working automatically. The fact there is no power switch is a turn off. Plug and play is one feature that some of the most expensive enclosures don’t have. It makes using the enclosure fun and easy.

Affordable Price

The external enclosure is one of the cheapest boxes out there it is even cheaper than the Sonnet Echo SE1 that also has PCle slots.  It cost $200 and you can buy it in various platforms including amazon. The price is fair if you consider the features it comes with including different PCle cards support.

Cross Platform

The enclosure works well on both windows and macOS as long as your laptop has a thunderbolt 3 port it can be used to enhance performance. It works well on any laptop or MacBook that has a thunderbolt 3 port. connection is very easy because the eGFx has plug and play feature.

A closer look at the Highpoint Rocketstore 6661A

The enclosure doesn’t support graphics cards but you use can various sizes of NVMe/PCle cards. The enclosure is a great performer depending on the card you choose to install inside. You can use the second Thunderbolt 3 port to connect up to six peripherals.

The enclosure is quiet because of the dual fans inside the eGPU cooling is highly efficient here. Installing any type of card inside the enclosure is very easy. You can use any X4, X6, and X16 card to your thunderbolt 3 external enclosure. It weighs 4.6 pounds and can be carried with one hand.

The metal build makes it sturdier and the size of the eGPU is amazing. It stands tall on a desktop and I prefer the general aesthetics of the external enclosure. Some compromises like the lack of a power switch might be a deal breaker to some people.

If you want a better performing enclosure the Razer Core X is priced higher than the Rocketstore 6661A but it cost much more. It will house various types of GPU and it is one of the best values for money external enclosures.

The Rocketsore 661A lacks a number of ports but when we consider the amount of money we are paying for the enclosure then I think it’s quite fair. The PCle box by highpoint has some amazing features that can improve your laptop. there are some compromises as well but it is one of the cheapest out there and we can’t really complain.

Pros of the Highpoint Rocketstore 6661A

Compact build – the enclosure has a very good build and I must commend highpoint for their efforts in creating the enclosure. We have a strong foot that holds the enclosure tight when placed on a flat surface. It is made completely out of metal and it has some openings that allows air to flow in and out of the eGPU.

Easy to use – the eGPU is very easy to use the moment you plug it into your laptop it starts working immediately. It lacks a power port so it has sensor that notify the enclosure if you connect it to your laptop. plug and play makes the process of using a laptop very easy and fun.

Affordable – the external enclosure is one of the cheapest out there and you can pick it up for less than $200. It doesn’t have high end powers like graphics boxes that house real GPUs. you can decide to pick it up if you want to start your journey into the world of enclosures.

Cons of the Highpoint Rocketstore 6661A

Lack of Ports – the eGPU doesn’t have the needed ports that can be used to attach more peripherals. It lacks a USB type A port, ethernet, and display port. every connection must go through the second thunderbolt port on the enclosure.

No Power Delivery – there is no power delivery on the Rockstore 6661A. the sonnet echo se1 that is a close competitor has 15W power delivery. The feature allows you to charge your laptop while using the external enclosure.


No Power Switch – the only way you can find out if the enclosure is powered on is if you connect it to your laptop. a power switch is very important because you will know if the eGPU is on or off. This single feature can be a deal breaker for some people who will be interested in buying the enclosure.

No, you can’t the enclosure only support some PCle cards you cannot use any type of graphics card inside the Highpoint Rockstore 6661A.

How much power in Wattage is being sent to the PCIe lane?

The enclosure sends 60W of power to the PCle lane which can be sufficient for most of the PCIe cards that will fit into the enclosure.

Can I use an x4 PCIe card in this?

Yes, you can even use an x8 or x16 PCIe card inside the Rockstore 6661A and it will work just fine.

Rounding up

The box is not as stylish as other enclosures out there and it lacks some ports and even a power switch. It offers a decent storage performance at a very affordable price. The Sonnet Echo SE1 and the akitio node are the closest competitors with the Rocketstore 6661A and they all share similarities and differences.
