Best External Graphics Card

best external graphics cards

Creating a gaming computer is often a matter of making the right compromises in the right places, and if you want to create a portable system, then you’ll have to make a few of them.

You can go for a small form factor build (like a mini-ITX or micro-ATX, but a lot of them are still relatively heavy and bulky, especially if you don’t opt for integrated graphics.

So what do you do if you want to game on a laptop or another equally-portable system?

External GPUs are one of the best ways to improve the performance of a computer without needing a bulky case to contain all of the parts. Laptops or cases like InWin’s Chopin are excellent candidates for external GPUs.

However, picking out the correct external graphics card can often be a challenge, especially if you’ve never purchased one before. You’ll have to account for matters like the power supply, portability, cooling, and more.

Today, we’re going to look at nine of the best ones around.

In each of our reviews, we’ll give you a short overview of each product, and then we’ll summarize what we liked about them and what we didn’t.

When we finish reviewing our top nine external graphics cards, we’ll also go over some of the features that you should look for to ensure that you get the best one.

The 9 Best External Graphics Cards

Gigabyte AORUS


For the price of many other gaming boxes alone, this one from Gigabyte comes with an Nvidia GTX 1070 already installed. Due to the inclusion of the GPU, this one is the perfect choice for customers who don’t already have a video card that they would like to render portable.

There are a few features on this portable GPU that help put it a step above other models in its price range.

To start off with, the looks of this model are aggressive, and they fit the color scheme of the GPU that comes mounted in it. While it’s on, you’ll notice the tasteful RGB lighting emanating from the floor of the box.

This eGPU is also designed to be as portable as possible, so it features a compact design that you can easily pack away.

The Gigabyte gaming box shouldn’t weigh you down, either, as it features a mass of only 4.4 pounds. While Gigabyte cards have a reputation for poor cooling, this one runs quietly and smoothly.

There are plenty of ports on this gaming box that help make it more versatile, and it features a Thunderbolt 3 output, ensuring that you can plug in an play with both laptops and monitors.

This gaming box also supports Quick Charge for laptops, giving you both a power source and extra power.

The inclusion of 3 USB 3.0 ports means that you can plug peripherals directly into this gaming box, making it ideal for smaller laptops that may not have enough of them.

The enclosure even comes equipped with a carry handle that will make it easier to bring around with you.

Using the Thunderbolt 3 connection, the Akitio Node can handle transfer speeds that range up to 40 Gbps.

This is also an excellent eGPU for Mac users, though it will require an additional script so that it can run on that OS. Keep in mind that this model will require a system reboot when it is first plugged in.

Despite the power supply from the Thunderbolt 3 cable, we would recommend plugging your computer in with a charger as the eGPU won’t be able to provide enough juice for heavy gaming.

Overall, this is an excellent budget external GPU for customers who don’t need a wide range of bells and whistles but would still like something reliable.

What we liked:

  • Excellent price
  • Very reliable
  • Removable panel for wider cards

What we didn’t like:

  • Plain exterior
  • Your computer will have to be rebooted when it’s first plugged in

Razer Core X

Razer Core X


If you want a more affordable alternative to the earlier option from Razer, their Core X is a little more compact, and it lacks some extra features like the RGB strips.

While it may look a little less exciting than the Core V2, this model is also about 40% more affordable, making it ideal for users on a budget.

If you’re looking for supreme value for money, then you’ll love the Core X, as it can work with a wide range of GPUs, and it features the high-speed Thunderbolt 3 connection.

When you’re connected using the Thunderbolt 3 cable, the Core X will be able to improve your computer graphical output and charge it at the same time.

The Core X can support a variety of graphics cards due to its large internal dimensions, with the ability to handle full-length and three-slot cards, which is a rarity in this price range.

Buying Advice

Is the GPU Included?

The first thing that you’re going to have to account for when picking out the best external GPU on the market is whether or not it has a video card already installed.

If you already have a GPU and you aren’t looking to upgrade, then one that comes included will be little more than a waste of money.

Most video card enclosures don’t come with a GPU, as that will allow you to select the ideal model for your system and install it yourself.

The ones that do come with graphics cards usually feature a midrange model like the GTX 1070 or the RX 580, though a select few come with more powerful cards.


Up next, you should take a look at the GPU enclosure’s cooling capabilities, especially if you’re going to use a high-powered card.

Most of the time, a GPU’s cooling fans should be sufficient, but cards that run hot will often need extra fans in the enclosure, and the majority will come with at least one of them.

Along with the included cooling fan, you’ll want to be sure that your enclosure is sufficiently ventilated, and a lot of them will feature holes for air along the sides.

You should also account for how loud the cooler is going to be and whether or not that would disturb anyone around you.


The whole point of an external GPU is to be more portable than a full gaming setup, but it won’t be too helpful if it’s essentially the size of a small computer. You’ll have to strike a balance between the enclosure’s compatibility with cards of various sizes and portability.

Some models will be compatible with the longest three-slot cards, but they will sacrifice quite a bit of compactness so that the GPU can fit in the first place.

You’ll also want to be sure that the enclosure isn’t too heavy, and you should account for the weight of the GPU that you’ll be adding.


The looks of your external GPU can contribute to your overall gaming setup, and you’ll want to think about how important they are to you.

Better-looking products are usually more expensive than plan GPU enclosures, and some of them will come equipped with RGBs controlled by proprietary software.

If you need a budget model, then you can sacrifice looks for superior capabilities at a lower price. You should also consider whether or not your GPU comes equipped with any RGB elements and whether or not they’ll be visible through the enclosure when it’s installed.

Power Supply

Finally, you’ll have to account for the power supply unit that comes installed in your external GPU, as the video card will still need a power source.

Most eGPUs will be equipped with a PSU that can provide anywhere between 300W to 650W of power, with the upper limit typically being more than sufficient.

Keep in mind that the power rating of the PSU is not analogous to the power draw of the GPU that you’re installing, and you’ll usually want about 100W of headroom (more if you’re overclocking).

Picking out the best eGPU doesn’t have to be a challenging matter, and we hope that we’ve been able to prove that throughout this guide.

Thank you for taking the time to read through our reviews, and we’d argue that any of these nine enclosures would be perfect, depending on your specific needs.
