News hardware With its GeForce RTX 4090, Nvidia will explode your energy consumption

Passed in the test phase for a few days, the future queen of graphics cards, the GeForce RTX 4090 from Nvidia, worries at the sight of its disproportionate energy consumption, and which might well cause some trouble in our current configurations.
After Ampere, place for the Ada Lovelace architecture to equip the RTX 4000
For the record, the future RTX 4000 cards from Nvidia take their name from Ada Loverace, a famous English countess, well known for having produced, in 1842, excuse me, what is considered to be the first computer program of history on Charles Babbage’s Analytical Engine. A true pioneer of computer science.
With each generation of graphics cards and processors, it’s the same old story, we increase in power, sometimes in size too, and suddenly to power everything, we use ever larger power supplies and it’s consumption that explodes .

Gone are the days when a 450W power supply was “more than enough”. Today the standard is more like 750 or even 850W and it might quickly become obsolete when we observe the first feedback from tests on future Nvidia GeForce RTX 4000 graphics cards equipped with Ada Loverace AD102 to AD107 processors.
Among the many references announced, we can deduce that the RTX 4090, will therefore be equipped with the AD102 processor and that it is no longer Samsung that takes care of the engraving, but TSMC with a new 4N process.
Soon standard power supplies at 1000 or 1200W?
If the first news announced a monstrous initial TBP (roughly the total power of the card), beyond 850 watts, it would seem that the reference model (the equivalent to the Founder’s Edition that we now know well) is actually around 600W.
For comparison, the RTX 3090 Ti, the most powerful on the market currently, is credited with “only” 450 watts, which is more or less what the future RTX 4080 should consume.
With custom, OC, Suprim, Ultra, etc. and others from third-party manufacturers, so we shouldn’t be that far from the 850 watts announced a few days ago by some well-informed leakers. The big question that torments us now is what machine will be able to run such monsters?
The first problem that immediately comes to mind is cooling. How do I prevent them from overheating? By putting bigger fans, will you answer me. But this implies two other immediate problems, the lack of space in the towers and the supply of all this factory.
As a result, still according to the first returns, it would take at least a 1000 watt Gold 80+ type power supply to run it all and some people don’t even hesitate to mention 1200 watts as the future standard.
If there is one that certainly sees these announcements in a good light, it is undoubtedly global warming, for which the plan is unfolding as planned…
