As you all know, it is expected that NVIDIA officially announce its new generation of graphics cards at this year’s CES, which will take place in just three days. Meanwhile, information continues to appear about the products they are going to present, with the RTX 5090 and RTX 5080 as the main protagonists, and now the information that has just been leaked about what it tells us is about consumption of these graphs.
It was known that, specifically the RTX 5090, would have quite high consumption, and there was even speculation that it would need two connectors 12VHPWRwhich are capable of supplying up to 600W of power each. In the end it seems that it will not be necessary and, in fact, it is something that was already denied a long time ago, but even so what does seem true is that the RTX 5090 will take the 12VHPWR connector to almost its technical limit.
It will no longer work with a normal power supply: the RTX 5090 consumes 575W
The information comes from an acquaintance leaker which in the past has had a very high success rate, so although it is obviously still a leak and not official information, we can take it as more than probable. The fact is that apparently the RTX 5090 is going to have a TDP of 575W, and despite this it will only need a single 600W connector from the power supply, although yes, as you will already assume, it will take it to the limit; Keep in mind that one thing is the official consumption and another is the real one, and apart from that, the assemblers will surely launch overclocked models that will increase the consumption, most likely reaching those 600W.
We are talking about 575W, so a normal power supply is certainly not going to work for you, even if it has plenty of power. We are talking about values that will push the power supply to the limit, which is why we consider it practically essential not only to have a high power and efficient source, but also to be from a Tier 1 manufacturer, yes or yes, we cannot take half measures when We are managing these figures.
Keep in mind that the current generation RTX 4090 already has a TDP of 450 watts, so if the RTX 5090 raises this figure to 575W, that’s 125W more, which is no small feat.
@hongxing2020 And RTX 5080 360W.

On the other hand, as you can see in the Tweet inserted above these lines, it is also said that the RTX 5080 will have a 360W TDP. This is much more reasonable because it is only 40W more than the current RTX 4080/RTX 4080 SUPER, and is in fact quite logical and certainly much more manageable, even for lower range sources.
As a summary, returning to the RTX 5090, it is assumed that it will mount the GB202 chip that has 21,760 CUDA cores (it will be the first to exceed 20,000 cores, by the way), accompanied by a whopping 32 GB of GDDR7 VRAM memory with a 512-bit bus, so it will be a real beast. As for the RTX 5080, in theory it will mount a GB203 GPU with 10,752 CUDA cores accompanied by 16 GB GDDR7 of VRAM. These data are based on rumors and leaks, but hey, there are only three days left until NVIDIA clears up our doubts.
