The NVIDIA GeForce RTX 4090 is officially available, following one of the most contentious graphics card generations in recent memory. Although RTX 3080 and RTX 3070 ampere-based GPUs possessed the performance, the cards themselves were hard to come by. A shortage of graphics cards was brought on by the global pandemic and only exacerbated by miners and other reasons. 

NVIDIA's RTX 40-series system requirements have been made public, and with all that power comes worries about how to prepare your PC. You should focus on the power supply unit (PSU), chassis, and any potential performance bottlenecks when configuring your gaming PCs for the RTX 4090 or any other NVIDIA GPUs from the next generation. 

1. Processor  

Having a power supply capable of keeping the fans running and a chassis large enough to house the behemoth are two different things. A performance bottleneck brought on by an out-of-date CPU and insufficient RAM can slow down the flashy new GPU. If it has been a while since your last upgrade, you may need to look for a new motherboard to accommodate the new CPU. 

So that your brand-new GPU may function to its full capacity, start with the CPU. We recommend choosing one that is well-suited for gaming. Check out our article on the top 5 CPUs for this card if you're interested, readers. Don't forget to add at least 16GB of RAM to the mix for the best performance. One should, at the absolute least, select an Intel 12600K or an AMD Ryzen 5600X from team Red. 

2) Room for the card installation 

Your choice of a casing for your PC build could make or break the undertaking. Mini-ITX, full-sized, or mid-sized cases should be the most popular sizes. This monstrosity ought to easily fit within full-sized cases. 

Check to check if the card will fit in your current case or the case you want to upgrade to. Dimensions of the Founders Edition card are 12.3 by 5.4 inches, plus 1.5 inches for attaching power cords. The case's GPU compatibility criteria should be disclosed by each vendor in addition to the Founders Edition specifications. 

Additionally, the card needs three slots at the PC's back, so make the right preparations. Make sure there are a few open slots underneath the card as a general rule so that there is ample space for airflow. 

3) Power supply specifications 

The PSU in your computer is a crucial part. Without it, your computer would just be a collection of metal as it powers all the other components. Because of this, buying a high-quality PSU is typically advised when building a high-end PC. A high-quality power supply is less likely to malfunction and fry any linked equipment in addition to giving the system the power it needs to remain steady. 

PSUs come in a variety of wattages based on the equipment you have. NVIDIA's stated recommendation for users of the Founders Edition RTX 4090 graphics card is to purchase an 850W power supply. The tests were done on a PC using an Intel Core i9-12900K, and these numbers are simply estimates. Only NVIDIA's own Founders Edition cards are covered by this; other AIB partners surely have various recommendations. 

When it comes to performance, the RTX 4090 is a superb GPU. Unfortunately, this necessitates such a massive design and comes at a greatly increased cost in terms of electricity and considerable thermal overhead. You require top-notch hardware if you want to get your hands on a brand-new flagship. All the necessary requirements for your system to make sure you get the most out of this GPU are covered in this guide.
