Best case for RTX 4080 – will the 4080 fit my PC case? (2024)

Nvidia’s RTX 4080 graphics card is out in the world, so we’re helping buyers choose the best case for RTX 4080.

Nvidia’s RTX 40-series is a big-boned family – and its performance has the strength to show for it. The 4080 has dimensions of 304mm x 137mm x 61mm. Like the recently released 4090 which eclipsed that of the Xbox Series S, you’re forgiven for wondering whether the RTX 4080 will fit your current PC case. Before that though, you might want to consider the best case for RTX 4080 Super instead.

The biggest competition of the RTX 4080 is the newly released RX 7900 XT & XTX. AMD are banking big on gamers not wanting to have to rebuild their rig to accommodate their new GPU, so have emphasised how small their new cards are.

However, for many, the sheer power of the RTX 4080, along with its recent price drop, will prove too tempting. Not to mention to joy and reward that comes with building a new PC.

We’re also helping prospective buyers out by offering a guide to the best CPU for RTX 4080, so don’t worry if you’re feeling overwhelmed by the prospect of spending over a thousand dollars on a new graphics card. Once you’ve chosen your graphics card, we can help you find the best CPU for the 4080 to ensure your hardware isn’t at risk of bottlenecking.

If you’re planning to upgrade to an RTX 4080, be prepared to grab a new power supply alongside your new gaming PC case. The RTX 40 series currently has a TDP of up to 450W, which is a factor in the size of case we’ve put on this list.

Let’s get into our picks. If you have any more questions, be sure to check out our detailed breakdown of specs, features and FAQs at the bottom of this article.

Nvidia’s latest GPU series comes with state of the art specs. Though this is all very exciting, this has had a knock-on effect on the amount of space you need for fans and radiators for adequate cooling.

We’ve been looking at trusted brands like Corsair and ROG Strix which will deliver on heat dissipation whilst also keeping your PC case nice to look at.

Features to look out for in RTX 4090 PC cases

So, you’ve got your hands on MSI’s Nvidia GeForce RTX 4080 Ventus 16GB and now you’re picking a compatible PC case. This is a really important step as it’s the difference between your GPU operating at full capacity or under.

Chances are if you’ve just shelled out on Nvidia’s flagship 4000 series, then you’ll want to ensure your new GPU is taken care of. Below we’re going to breakdown the key features to consider including size, airflow and ports so you get the best case for your 4080.

GPU Compatibility

First things first, you need to make sure your 4080 physically fits inside the case you’re about to buy.

The factors that will affect the amount of space you have include AIOs, water-cooling tubes and drive cages. We also recommend leaving space for additional fans you might buy further down the line.

It’s much easier to prepare for the extra space now than have to upgrade your PC case again. Bear in mind if you try to ignore this problem of space, the performance of your GPU will suffer!

As a final word then, we think bigger is always better when it comes to PC cases, just so you’re bases are covered.

Airflow

Probably the second most important factor is thermal performance, especially if you’re buying Nvidia’s RTX 4080 is airflow. You’ll want to look at either a glass or mesh case, ideally with a dust filter to keep your internal hardware clear and cool.

For reference, the RTX 4080 needs a suggested 700W (150W than the RTX 4090).

Ports

The idea with this is to make sure you’re not buying a PC case with limitations to the amount of ports you can use.

The RTX 4080 has 1 x HDMI 2.1, and 4 x DisplayPort 1.4a, and you might have to consider buying longer cables to ensure they can be tucked neatly away.

Are third-party RTX 4080 different sizes?

Nvidia’s GeForce RTX 4080 measures 336 mm x 140 mm 61 mm (L x W x H).

You’ll find that third-party RTX 4080 are different sizes. For example, the ROG Strix PC cases tend to be slightly larger than other models, so attention to the specs before committing to a card.

Do I need a new PSU for my RTX 4080?

It depends on the third-party RTX 4080 you’re going for, but if your current PSU has a power supply of around 750 watts, then your RTX 4080 will be fine for an upgrade.

We’ve got you covered though if you’re looking for a guide to the best PSUs for your RTX 4080.
