Although it may sound strange, owning a regular laptop and not a gaming one, doesn’t necessarily mean you have to give up on serious gaming. Now, thanks to external GPUs, you can enjoy the benefits of the desktop graphics on your notebook. eGPUs only require a Thunderbolt 3 connection, and all the traffic and communication between the two devices is done through it.

Since this is a relatively new type of hardware, without much of previous experience, finding the best eGPU might present a bit of a problem. However, with a few instructions and guidelines, it should be achievable.

How to Choose the Best eGPU

As mentioned, finding the best eGPU, might be a problematic experience, especially if you have never encountered this type of device. Nevertheless, there are a few characteristics that make the biggest difference and allow you to determine which devices you should avoid, and which ones you should seriously consider, and they include the following:

Supported Card Size

The last thing you need is to purchase an expensive external GPU enclosure and realize your planned GPU cannot fit inside. Therefore, before the buy, do thorough research and find the enclosure that can accommodate the desired card.

PSU Wattage

Higher PSU wattage means that your enclosure will be able to provide more power for both your notebook and the card. In other words, insufficient power wattage may prevent you to use a certain card or notebook. For that reason, go for as high numbers as possible.

Cooling solution

When talking about external graphics cards enclosures, one of the most important aspects is definitely their cooling, especially if you are into overclocking. For that reason, go for the devices that are equipped with large fans or support installation of liquid cooling. That way, you will both protect your hardware, and save yourself from a lot of trouble.

Connectivity

More connectivity ultimately leads to more versatility, which is always good, regardless of the type of device are you dealing with. For that reason, a variety of additional connection options is definitely something you should go for.

Akitio Node

akitio node
Akitio Node is one of those external GPU chassis that offer good compatibility and decent performance at a fair price.

An Affordable, yet Very Good External GPU Enclosure

Alienware Graphics Amplifier (9R7XN) is a fair-priced, sleek-looking GPU enclosure that offers good connectivity and durability, but can be paired only with a small number of devices, or more precisely, only with Alienware laptops.

This is quite a large device, with 3.5 kg of weight and a very stable build that should protect it from any physical damage.

Alienware Graphics Amplifier (9R7XN) is fitted with a 460W PSU and works with both AMD and Nvidia GPUs (as long as their power consumption doesn’t pass the 375W mark). This enclosure is capable of holding single, dual wide PCI Express x16 graphics cards and comes along with four USB3.0 ports for additional connectivity.

However, as mentioned, Alienware Graphics Amplifier (9R7XN) is compatible only with Alienware laptops, principally, because each of its connections is performed through the proprietary PCIe connector, not a regular Thunderbolt port.

  • Durable
