Where are you getting the 25W from?

The 3090 has a TGP(Total Graphics Power) of 350W. That is the base specification. With the 12 pin connector, which are just 2x8 pins, the GPU will be able to draw an absolute maximum of 375W. That's not much room to grow. For comparison the 2080ti had 250W TGP. An overclocked 2080ti at 2000MHz will already draw close to the max of 375W.

Now unless I'm getting something wrong here if the basic configuration, read non-OC, is already close to 350W then there isn't much room to the physical limit of 375W.

If the way you are calculating the max 375 Watts is by adding the standard specification for those 8 pin connectors and then adding PCI-E wattage, so 150 Watt + 150 Watt + 75 Watt, we have seen in the past that those connectors can provide a lot more power than the standard specs suggest as long as the power supply is capable of it.

For example, if you take two very power hungry cards, the Titan Z and 295x2, both of those only have dual 8 pin connectors. Not more than that yet their estimated power draw is almost 500 Watts. It's why the recommended power supply is 750 Watts at a minimum and it's highly recommended to get 850 Watts or more. And you could overclock those on top of that.

And of course, there's the third method of AIB partners adding more connectors like Zotac is doing.
