With the price of the electricity bill increasing everywhere in Europe and the ecological awareness of citizens, it is now difficult not to think about the energy consumption of a PC. Where before you could leave weeks or months on without turning off, this is no longer so common and it seems that with the next RTX 4090 and RTX 4090 Ti things will get more complicated, unless you own one an electric one. This will be the consumption of the high-end RTX 40.
We talked about it a lot and in the future we will continue to do so, it’s always the sauce of the hardware, especially if the information has a base and comes from technological information leaks which in the past have been -on several occasions- reliable sources of information.
NVIDIA RTX 40s are expected with a TDP of 600 W
Unsurprisingly and even if since the NVIDIA GTX 700 series the TDP consumption of graphics cards has decreased significantly and the PDT very correctly. The increase generation after generation in the performance of these and the rest of the hardware makes us suppose, without a large margin of error, that the next generations will have a consumption that is not restricted at all.
According to information obtained through a conversation between two informants on Twitter, we can understand that the next series of graphics cards from the Californian NVIDIA will be RTX 40 -Lovelace- series will have a TGP greater than 600W.
1000W is not enough. I don’t know if it’s 4090 or 4090TI, but there is a model that can reach 600W.

If this is correct, as stated in the exchange itself, we can expect that for systems with a Intel i9-13900K next to one of these graphics RTX4090Ti we should have at least one power supply unit (PSU) of more than 1000W, surely 1200W to achieve maximum efficiency. This information is what indicates that for the use of 18.432 CUDA requires a lot of power, which is calculated in a TGP for at least 600W graphics as we mentioned.
More power, more consumption
Wait i9 13900K + RTX 4090 Ti recommend PSU at least 1000W GOLD

If all this is true – rumors – assemblers and users should start looking for sources of at least 1200 W, a source that normally does not currently fill the shelves of stores and although they may seem very alarming details, they don’t. Many years ago these PSUs were mounted on relatively less powerful equipment and we are not talking about mining rigs, but normal and current gaming equipment.
The switch to Ada Lovelace with her “performance double” promises a lot of power. Some of us still remember AMD’s words back when they said that if you wanted power, you had to have power. Well, NVIDIA with this new family, even though the 600W of TDP may really seem crazy compared to Ampere in performance and consumption, it implies that if this is what is expected, the RTX 40 will not have a energy efficiency as exorbitant as possible come and think.
We still have a lot of details to know about this new series of RTX40 and we still have room until he leaves, they are expected 66.4 TFLOPS in Fp32 at 1.8 GHz, which would only be “double power” compared to an RTX 3090. In any case, the electrics are rubbing their hands, NVIDIA is already savoring the dollars it will bring in and users are trembling before this uncontrolled advance, since the vast la majority should go through the box to acquire a new PSU bill.
