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.


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.
