NVIDIA’s GeForce RTX 4090 Ti Lovelace GPU Might Consume Over 800W Of Power

@kopite7kimi and @Greymon55 are considered quite reliable sources when it comes to graphics card leaks and rumors. These two leakers have become sources of many rumors lately.

We have heard a lot of news and rumors about NVIDIA’s next-generation GPU family based on its Ada Lovelace architecture.

Greymon55 had given a statement last year in November that if the hardware enthusiasts were prepared for double the performance at double the power consumption. The statement felt extremely unreasonable at that time but further leaks after that verified the concept.


Over the last few weeks, we have been listening to rumors that the top-end Ada Lovelace parts are going to be the thirstiest GPUs to ever exist. According to Kopite7kimi, a range from 450 Watts to 800 Watts for the top-end RTX 4000-series GPUs can be expected. Greymon55 passed similar comments regarding this, but the leakers did not take the risk of confirming any of those specifications.

Recently, both the leakers have been talking about the same concept with just a little more confidence. Kopite7kimi states that he’s been told a Total Graphics Power (TGP) of 600W has been verified for the hypothetical “xx90”-series part. That would max out the power draw of a PCIe 5.0 power.


We know that “xx90” is not the top-end part of NVIDIA’s series. It could be an “xx90 Ti” card, and according to Greymon55, if the RTX 4080 has a 450W TGP and the RTX 4090 has a 600W TGP, then a supposed RTX 4090 Ti could have an “800W+” TGP!!

If this is the case then even a brand-new 12VHPWR connector would require a second 12VHPWR connector. This has not been mentioned as an option in PCIe 5.0 or ATX specifications. On the other hand, board manufacturers could do something different, like including an old-school 8-pin connector along with the 12VHPWR connector; in combination with the PCI Express slot itself.


kopite7kimi proposed the idea of a four-slot air cooler in reply to a question in the comments. We’ve seen such a thing on the leaked GALAX GeForce RTX 3090 Ti, and AORUS also sells its GeForce RTX 3090 XTREME 24G model with a four-slot cooler, but requiring such a thing on the reference card is as-yet unheard-of.

Keeping in mind the practical necessities of such a huge power requirement, it seems rather doubtful. However, we can expect new and different things from NVIDIA. Also with all the great things we’ve heard so far about Ada Lovelace and the RTX 4000 series graphics cards, it seems everything is possible.
