4 things to consider before you buy RTX 5090

NVIDIA’s GeForce RTX 5090 is the most powerful consumer graphics card you can buy in 2025. One of the main reasons why it costs $ 2000 is that there is no competition from AMD and Intel. However, even if you can afford to spend so much money on this leading graphics card, you need to be very careful as there are some important factors to consider before you put it in your case. Otherwise, you may need to spend even more on additional components to enjoy all the profits of the productivity it brings on the table.

The size of your computer

Only the Edition of the Founders will fit in most mini-ITX cases

Nvidia somehow managed to make the RTX 5090 Edition Edition Graphics Card with two slots, although it is more hungry for power. This is great news for people who have small PCS forms, as the RTX 5090 FE would comfortably fit inside them. However, most third -party air -cooled graphics cards take at least three or more slots, which means that at least you will need a middle tower case to make sure you are not stewing your graphic processor.

Take a look at the RTX 5090 Astral by ASUS. This is a 3.8-layer beemot on a graphics card. There is no way to fit in some of the best mini-ITX PC cases Like the cool main NR200P Max and Lian Li Q58. Even if you can modify your small PC case factor to make room for the RTX 5090, it will work quite hotter than it would be in an airflow case from a middle tower or a full tower.

The power of your PSU

1000W PSU is the largest minimum

The RTX 4090 required at least 850W PSU as it had a thermal design (TDP) of 450W. Unfortunately, the RTX 5090 is even more hungry for power, with a TDP of 600W. So, to provide adequate power to all components in your computer, which includes your processor, RAM, motherboard and hard drives, you will need at least 1000W PSU. In some cases, even this may not be enough.

For example, Palit recommends 1200W PSU for its high class RTX 5090 Gamerock OC. This may be necessary if you are planning Adultens your graphics card To get even better prices for the staff in your games – which is my many people who buy bee graphics cards for the after -sales market with three (or more) fans. So if you have an 850W PSU that you have purchased with your 4090 construction, you will need to spend some money for new power.

12VHPWR cable

You need a 12VHPWR cable rated for 600W

Not all 16-pin (12+4) GPU power cables are the same! Nvidia introduced this relatively new power cord with the RTX 4090 in 2022 and every 16-pin power cord will work with it, as its TDP is 450W. However, as I mentioned above, the RTX 5090 can draw up to 600W power and you need a cable that can handle this power.

If you have ATX 3.0 power supplyYou have to be good because you will find these cables in the box. Otherwise you will need to buy a 12VHPWR adapter or cable set from third parties from CablemodS More importantly, you have to make sure that the cable you buy will support the power you have; You should not use a cable kit that is designed to power Corsair with a cool main PSU.

Your current processor

If not fast enough will transfer the RTX 5090

If you want to extract the most productivity from the new RTX 5090, you need the fastest processor you can currently buy, which is AMD Ryzen 7 9800x3D. Even if you have a slightly larger chip like 7800x3d or Intel i9 14900K, you will not get NVIDIA claim rates. You will be limited to about 90-95 percent of its presentation. All the older and you have almost flooded your graphic processor. As your processor is not fast enough to keep up with the RTX 5090, the use of the graphic processor will be very limited, especially when playing high -foot games.

More importantly, the RTX 5090 is really worth it only if you plan to start games with 4K resolution. Even at 1440p with the fastest playing processor, 9800x3d, 5090 is only 12 percent faster than 4090 Hardware does not connectS And at the 1080p RTX 5090 barely offers improvement. So, if you are a competitive gamer who has a 1440p/360Hz monitor or better, do not upgrade from the RTX 4090 before you first upgrade your processor first.

You need the right hardware to get the most out of RTX 5090

With $ 2,000, the RTX 5090 is already too expensive, but if you no longer have a high -end hardware on your playing computer, you will need to spend even more money to get perfect performance. It doesn’t matter if your computer can handle the RTX 4090, as 5090 is even faster and more powerful and as a result you need to install it. Otherwise, you will end up transferring your glossy new graphics card and this is just a loss of your hard money.
