The perfect alternative to desktop-level performance on your laptop. Check out these external graphics cards tailor-made for eGPUs.

The only alternative to enjoy desktop-level performance while having a highly functional lightweight laptop is using an external GPU enclosure.

eGPUs provide extra graphics processing power much like an external hard drive does for data storage. 

The eGPU doesn’t necessarily come with an installed GPU. Instead, these are just a case with the necessary interface to directly cycle the graphics card.

Whether or not, an eGPU is suitable for your needs, depends only upon the intended purpose. eGPUs are a great option for saving space and turning your regular laptop into a gaming and editing powerhouse.

Are eGPUs worth it?

Are eGPUs worth it

eGPUs are a boon for people who want a gaming system but don’t have space for a bulky gaming tower. The benefit of using a graphic enclosure is particularly connected with two main variables – 

  • Space
  • Mobility

A full-size gaming tower requires a lot of space, which everybody doesn’t have. Then there’s the budget part of it. But using an eGPU provides the flexibility to upgrade your normal laptop into a gaming rig.

You can further upgrade the enclosure with the latest graphics card much like in a gaming PC. This flexibility is not available with a gaming laptop as the GPU there is integrated with the motherboard.

Consider a gaming laptop like the Acer Predator Helios 300 with RTX 2060 graphics card. It weighs in at 5.1 pounds while a Macbook Pro having similar specifications with the exception of a graphics card weighs just 3.1 pounds.

An office goer or traveler is more likely to consider a lightweight portable laptop – more functional and easier to carry around. At the same time when they return home, they can plug in their external video card for laptops to enjoy desktop-level gaming performance.

Graphics cards in eGPUs require a dedicated power source though, apart from the PCIe interface it needs to work with the laptop.

Hence these units are available in two form factors, viz. –

  • Integrated Power Source

eGPUs with integrated power sources are bulkier as the power adapter is integrated within the eGPU case. These devices also generate more heat, not welcome in case you’re looking for a few hauls on Warzone Battle Royale.

  • External Power Source

eGPUs with a charger-type external power adapter make the actual GPU much lighter and compact. The adapter can further be placed on the ground to save space. However, you will still have to carry it around. Considering portability, eGPUs with integrated power sources fit easily in a conventional laptop bag.

How to Use an External Graphics Card to a Laptop?

How to Use an External Graphics Card to a Laptop

Despite the number of available methods to connect an external graphics card with your laptop, the process itself is quite long and complicated.

Apart from an eGPU, you can use a graphics card dock to use a graphics card with your laptop. These docks come with a power adapter, PCI Express slots, USB cable, and HDMI ports.

Using such an unconventional connection method requires establishing a manual connection with internal ports using mini PCIe cable, NGFF cable, or m.2 cables.

You will have to open the access door and unplug the WiFi-LAN card or remove the SSD from the M.2 slots to connect the card.

Most such connections will require you to create a hole on the access panel to pass the wires. Or, you will have to remove the access panel altogether and proceed.

You will also need an external power source to run the graphics card, preferably 20-30% higher capacity than the power capacity of the GPU. Even then your work desk will be a mess full of tangled wires and open circuits.

After completing the connection, you will have to manually disable some BIOS settings and install the latest graphics driver to enjoy gaming on a budget.

The worst part is that there is no documentation or connection module provided with graphics docks making it highly user-unfriendly. It makes the entire process of connecting the GPU with your laptop a risky job as one short circuit can fry your entire laptop or damage your internal devices.

The best possible way is to use a thunderbolt 3 EGPU enclosure.

Wait up though.

These are just the basics of using an eGPU with your laptop for gaming or editing. Optimizing performance, finding that sweet spot between peak performance and low wear needs a bit more in-depth know-how.

How to Choose an eGPU? Buyer’s Guide

There is a wide range of graphic cards/eGPUs that you can purchase on the market. While the basic connectivity includes a power and Thunderbolt 3 USB connection, the governing factor of any graphic card with an eGPU setup is the power output.

For example, the Razer Core X Chroma comes with a 700-watt PSU, making it powerful enough to accommodate graphic cards with a dedicated power requirement of up to watts.

Most eGPUs come with a minimum power supply of 300-400 watts, enough to run low and midrange GPUs. Hence the eGPU you choose will limit the graphic card compatibility.

We recommend buying an eGPU with at least 400 watts of power supply for further upgrades.

With the release of high spec GPUs, eGPU manufacturers also release compatible versions soon after.

So, you can even run the latest RTX 3090 card using the Mantiz MZ-03 Saturn Pro II EGPU.

An eGPU is a functional piece of equipment but only for those who don’t mind spending the bucks for add-on graphics processing power. The cost of just the enclosure is higher than a motherboard to house a graphic card. But it is a great choice to gaming performance to your laptop without tinkering with what’s inside it.

Some advice – always try to opt for eGPU enclosures with internal power supplies above 550 watts. You can get a cheap eGPU enclosure, there are many on the market (not on this list!) But you increase the chances of losing out on power and crashing midway through the game, causing hardware and maybe even software damage.

Either way, eGPUs and eGPU enclosures for laptops are more than worth it. Get one today!
