The GPU (graphics processing unit) enclosure is an external graphics card holder, widely known as eGPU (external GPU). By plugging in an eGPU enclosure to your computer, you can use the externally connected graphics card.
A good gaming experience demands crisp graphics and video quality. Often, the computer/PC you own may not have a full-fledged in-built graphics card or maybe an older version. Here is where eGPU enclosures play an active role to cater to your effortless and up-to-par gaming requirements through an eGPU.
Things you need to know before you purchase an external GPU enclosure
-
Not all enclosures come with a GPU
It is important to remember that most GPU enclosures do not provide a graphics card. GPU enclosures are usually a box-like device with a power supply, a space to accommodate graphics cards, and multiple ports. So, you will have to purchase a graphics card individually after getting a GPU enclosure.
-
A replaceable power supply unit
Several eGPU enclosures come along with PSUs (power supply unit). In some types of eGPU enclosures, the PSUs are replaceable. When purchasing an eGPU, one clever tactic to apply if you are on a budget is to buy an eGPU with a substandard PSU unit. You can later replace them with a robust PSU unit.
-
The necessity of a Thunderbolt port
One pre-requisite to using an eGPU is the requirement of having a Thunderbolt port on the eGPU enclosure. A Thunderbolt 2 port is more familiar with the older models. However, since the thunderbolt two has a lower bandwidth, Thunderbolt 3 is the more common and preferable. The max power output of a Thunderbolt 3 is substantially low, and it can deliver a power of about 100W.
-
Check the compatibility
The last thing you would want to do is check if the eGPU you have in mind for purchase is compatible with your working devices. Some eGPU enclosures can only work and function with a single type of Operating System. In some cases, external GPU enclosures are compatible with just a few Mac, Linux, or Windows Operating Systems versions.Â
