¿Qué fuente de alimentación necesito para una GeForce RTX 3090 Ti? 28

What power supply do I need?

Posted by

The launch of the GeForce RTX 3090 Ti occurred last March 29. In the end, practically all the leaks that we had been seeing were confirmed, including those related to its specifications, its TGP and also with the adapter of three additional power connectors from 8 pins to one of 12 pins.

Numerous performance tests have confirmed that the GeForce RTX 3090 Ti performs, on average, 5% to 10% more than the GeForce RTX 3090 depending on the resolution used. The smaller the resolution, the smaller the difference, so that maximum value of 10% is only reached with 4K resolutions.

Its performance values ​​are pretty clear, but what about consumption? This is very important information, since it will help us to solve one of the questions that those who are considering buying a GeForce RTX 3090 Ti are asking themselves the most, and that is that these They are not sure what power supply they will need.

GeForce RTX 3090 Ti: Your power supply may not be enough

Although the TGP that NVIDIA has listed for the GeForce RTX 3090 Ti is 450 watts, depending on the model we buy, the actual consumption can peak up to 511 wattswhich means that if we have, for example, a 650 or even 700 watt power supply, we may not be able to move it with guarantees, due to those maximum peaks and the added consumption of the rest of the components.

To understand it, I am going to give you a concrete example that will be of great help to you. A rig configured with a Ryzen 7 5800X at stock frequencies, 16GB of dual-channel DDR4, two PCIE NVMe SSD storage, gaming keyboard and mouse, discrete RGB LED lighting, six fans, and a Corsair iCUE H100i liquid cooling kit RGB ProXT It would have a load consumption of 709 watts. This consumption represents the average value, and does not reflect possible maximum peaks.

If we have a team similar to the one we have set as an example, it would be recommended have at least an 800 watt power supply, since hurrying and opting for a 750-watt one would be a clear risk when it has to face those maximum consumption peaks. On the other hand, if we plan to overclock, or if we have more fans or a more complex RGB LED lighting system, we would have to opt for models of 850 watts or higher, depending on the final consumption.

You don’t need a 1,000-watt power supply, but you do need a quality one

In general, any powerful high-end team that aspires to mount a GeForce RTX 3090 Ti will need, at a minimum, a power supply of between 800 and 900 watts, as we have already said in the previous paragraph. However, keep in mind that this should meet other important conditions To ensure optimal performance:

  • When we move in such high consumption it is essential to choose a quality source since its components will be prepared to withstand the stress that this type of consumption represents without problems.
  • must have three additional 8-pin power connectorsas we will need them to connect to the 16-pin adapter included with the GeForce RTX 3090 Ti.

With everything we have said in mind, you can assess for yourself if your power supply will be capable, or not, of moving a GeForce RTX 3090 Ti. I also want to leave you a series of recommendations that will serve as a reference when choosing a new power supply, in case you have no choice but to change it to be able to get the GeForce RTX 3090 Ti.
