1.Gigabyte AORUS Gaming Box

Gigabyte AORUS Gaming Box

Gigabyte is a top-rated company that provides computer hardware with so many features. When it comes to the AORUS gaming box, it is an external GPU casing that is filled with Gigabyte’s famous Mini ITX edition of the GeForce GTX 1070. It is a beautifully designed metal casing with a transparent web displaying the face of the graphics card and further highlighting it with LED lighting.

As this external graphics card is shipped with Gigabyte GTX 1070 Mini ITX, it has all the fantastic features. On the other hand, this graphics card has limited overclocking abilities because of its compact cooler and tiny size, and the system gets loud when under a lot of loads. Despite that, it is still a reliable external GPU that can deal with both VR and 4K gaming.

When it comes to its design, there is not much to explain – the exterior is neat and minimal, but the RBG LED lighting on the face of the graphics card illuminates its quality and offers that perfect gaming feel. If you want to control the lighting, you can use the Gigabyte’s AuraSync application, which lets you control and customize the light the way you want. Other than that, the RGB effects can offer static, breathing, color cycling, and flash abilities.

When we discuss its connectivity, there is no problem here. The case is featured with a Thunderbolt 3.0 port, which helps to interface with the PC or a laptop, while the GPU is equipped with an HDMI 2.0 port, two Dual Link DVI-D ports, and a single DisplayPort 1.4.

Other than these fantastic basics, Gigabyte has enhanced the case one step farther, and it offers four USB ports, one is a charging port, and the rest of the three are standard USB ports.

Another great thing about this external GPU is that it is very lightweight, and has a tiny frame, which makes it one of the best and most portable external GPUs available in the entire market.

2.Alienware Graphics Amplifier

Alienware Graphics Amplifier

Alienware became an independent company in 1996, but it only reached recognition when Dell bought it in 2006. For so many reasons, Alienware became expensive gaming hardware, so it is common to see external graphics ideas from them.

The Alienware Graphics Amplifier is known to be a wonderfully designed GPU casing that works only with Alienware hardware, with the manufacturer’s proprietary docks instead of the commonly used Thunderbolt 3 for connection purposes. The primary purpose of developing this remarkable external GPU case was to contain a fully-powered graphics card, so you cannot add this external GPU in the list of portable ones.

The exterior of this product is black and made of plastic with a powerfully detailed face and a well-designed Alienware logo, and that’s what makes the Alienware Graphics Amplifier a well-recognized Alienware hardware. As mentioned in the beginning, it is cumbersome and contains a footprint, but that’s not much of an issue when you think about the fact that the product wasn’t supposed to be made portable.

However, you can’t expect the case to be shipped with a graphics card, but you can expect Alienware to support a powerful graphics card that is as amazing as the Radeon HD 5000 and the GTX 600 series. Other than that, the 460-watt system can handle graphics cards with TDP of 375W.

Fantastic news about this graphics card is that it is equipped with four important USB ports that make it easy to connect or charge anything piece of equipment.

On the other hand, when we come to the downsides of this product, there are some particularly terrible problems with this external GPU case because it has limited use, and its size is not easy to handle. So, if you don’t mind the size and you have an aforementioned Alienware hardware that contains a proprietary connector, you can make it work.

Also, this is an affordable external GPU, and it is feature-filled. So, what’s not to like about it? If we ignore its size, we can make good use of it.

As a final verdict, the Alienware Graphics Amplifier is the ideal option for Alienware laptops. It not only kicks your gaming laptop but also increases your experiences. However, the only drawback to this product is that it is only limited to certain Alienware laptops, but it is a cheap product – so that’s a plus.

  • Easy to enhance
  • Affordable
  • Can handle many types of GPUs
  • Four USB ports
  • Not compatible with all Alienware laptops
  • Not so portable

3.Akitio Node

Akitio Node

Akitio is a trendy name in the whole hardware industry. It is known to be an international company located in California, which particularly deals in external expansions chassis and storage solutions. They use unique and historic designs to interpret their abilities. Every Akitio product is based on durability, reliability, and excessive features. Other than that, it has a pretty sweet exterior design, which you will get to notice once you hold the product.

Now, let’s move onto our product – The Akitio Node. It is an adaptable and spacious GPU case. However, from the looks, it seems like a reminiscent fully-packed small ITX computer case, more than any other reviewed product in this entire list. But, that leads you with both disadvantages and advantages.

We can’t praise the design enough; it is equipped with a general and simple looking design, entirely built from sheet metal. When it comes to its weight, it is quite heavy, and it doesn’t even come with a graphics card, which is a huge bummer.

On the good side, you can receive a large amount of everything with the 400W supply, and the ample interior will leave you in shock. If the size is not an issue, then this graphics card is the best one for you.

When we talk about GPU compatibility, the system supports both Radeon and Nvidia GPUs, including the GTX 900 series, and Radeon RX and R9 cards. What’s more, the system also supports Nvidia Quadro GPUs.

From the connectivity point of view, Akitio Nade is fantastic. As it is huge and bulky, it cannot be carried around quickly, and the Akitio developers were aware of that, which is why they added the handle on the upper back of the case. The handle makes it easier for you to carry it wherever you want.

Dimensions22 x 10 x 15 inches

In the final verdict, we can conclude that the Akito Node is a great product. The major advantage we receive from it is that its size is very compact. It can contain any GPU, but that still doesn’t make it the most portable eGPU in this entire list of ten best external GPUs. Other than that, it is a bit expensive, and if you want an external GPU that is suitable for home use, then selecting the Node would be your best option.

  • Bulky
  • Large
  • Zero USB ports
