The GeForce RTX 3090 Ti started last March 29. In the end, virtually all of the leaks we saw were confirmed, including those related to its specifications, its TGP, and also the adapter of the three additional power connectors from 8 pins to one of the 12 pins.

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

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

GeForce RTX 3090 Ti: Your source may not be enough

Although the TGP that NVIDIA introduced for the GeForce RTX 3090 Ti is 450 watts, depending on the model we buy, the actual consumption can reach a maximum output of 511 wattswhich means that if we have, for example, a 650 or even 700 watt power supply, we don’t have to worry about it, due to the maximum peaks and the added consumption of the rest of the components.

To understand this, I will give you a specific example that will help you a lot. Kit configured with Ryzen 7 5800X on storage frequencies, 16 GB dual channel DDR4, two PCIE NVMe SSD storage, gaming keyboard and mouse, discreet RGB LED lighting, six fans and Corsair iCUE H100i RGB ProXT liquid cooling kit The load consumption would be 709 watts. This consumption is an average value and does not reflect possible maximum peaks.

If we have a team similar to the one we gave as an example, it would be recommended have a source of at least 800 watts, because rushing and opting for 750W would be a clear risk when facing the maximum peaks. On the other hand, if we are planning to overclock, or have more fans or a more complex RGB LED lighting system, we would have to opt for models with an output of 850 watts or higher, depending on the final consumption.

You don’t need a 1000 watt power supply, but you need quality

In general, any high-end team aspiring to install the GeForce RTX 3090 Ti will need at least a power supply between 800 and 900 watts, as we said in the previous paragraph. Keep in mind, however, that this must meet other important conditions To ensure optimal performance:

• When we move in such high consumption, it is necessary to choose quality source because its components will be designed to withstand the load that this type of consumption represents without any problems.
• must have three more 8-pin power connectorsbecause we will need them to connect to the 16-pin adapter supplied with the GeForce RTX 3090 Ti.

With all that we have said, you can judge for yourself whether or not your source will be able to move the GeForce RTX 3090 Ti. I want to leave you too a number of recommendations which will serve as a reference when selecting a new source in case you have no choice but to change it in order to obtain the GeForce RTX 3090 Ti.
