The RTX 4090 is one of the best GeForce GPUs. It is also one of the fastest-performing GPUs in the market. It has shown enormous improvements in terms of performance and AI-powered visual effects.

You can experience high-performance gaming with the RTX 4090. It has the third generation ray tracing cores, which will help you experience the virtual world like never before. There is no doubt you will require a good power supply and high-performing PSU to enhance the gaming experience with the RTX 4090.

The RTX 4090 delivers excellent gaming performance. While many of Nvidia’s graphics cards are known for hitting remarkably high clock speeds, even crossing the 3GHz mark, some of Nvidia’s cards require intense PSUs. Pairing the GPU with a good CPU/PSU will help you make the best out of it. In other words, you may require a 1200W PSU to run the RTX 4090.

The card has a TBP of 450W, and Nvidia recommends using 850W of power supply to run it smoothly. The Asus ROG Strix model recommends a 1000W PSU. The MSI, Galax, PNY, and Inno3D recommend a PSU of 850W.

Now with all that performance, we do see an increase in the board power of the card. Which also increases the thermal energy produced by the chip. This leads to some intense cooling solutions, especially with air-cooled solutions.

We see the new cards reach a large size and weight. As such the ROG Strix comes in at 2.5kg and that is only attached at the PCI interface and IO at the back. This can lead to the bending of the card over time, which leads to damage and possible loss of performance or the resale value of the card.

It is very important to get GPU support with RTX 4090 to gain optimum results. GPU makers recommend GPU support to make the most out of the entire build. The performance of your whole gaming PC depends upon GPU support like PSU. Some cards may come with one, but you can find better options elsewhere.
