Nvidia’s 40-series GPUs can blow the lid off your power supply

Throughout 2022, there has been a steady influx of reports regarding the power requirements of Nvidia’s next-gen RTX 40 GPUs.

As such, it’s no surprise that upcoming boards will feature a three-fan reference cooler.

Speculation surrounding the power requirements of the RTX 40 cards has pointed to some units reaching 900 watts of power, which naturally suggests that an upgraded power supply will be an unavoidable necessity for consumers.

This hypothesis is supported by a new leak from Kopite7kimi, who has been at the forefront of RTX 40-related rumors. As reported by VideoCardz, the insider said that Team Green apparently designed a three-fan cooler for AD102 powered reference boards.

It’s important to note that Nvidia’s reference cards typically don’t exceed two fans. This means that GeForce RTX 40 graphics cards could consequently run hotter than their predecessors, and therefore require an improved three-fan cooling system instead.

So it seems that all the rumors about the unprecedented power requirements are actually true. Nvidia’s next cards could approach the 600 watt mark. And as we mentioned above, in some cases we’ve even heard of some units delivering an unheard of 900 watts of power. So it’s not completely out of the question that Kopite7kimi’s claim carries some weight.

Of course, if the aforementioned report indeed turns out to be correct, we will undoubtedly see a considerable increase in performance. Case in point: the RTX 40 series is expected to more than double the teraflops (TFLOPS) of the 3090 Ti, which is already among the most powerful GPUs ever released.

The AD102 is the GPU chip that would power the RTX 4000 product line, which means we could very well see one of the flagship models, the RTX 4090 Ti, sporting a reference cooler with three fans.

VideoCardz points out that almost all custom RTX 3090 Ti models require a three-fan cooler or hybrid liquid solutions. For example, we’ve seen how the 3090 Ti variants made by Colorful and EVGA are designed with 3.5 to 4 slots to accommodate its unprecedented cooling fan system.

In any case, VideoCardz points out that Nvidia has in fact never implemented a three-fan cooling solution for any of its older GPU reference models, nor integrated liquid coolers.

If Nvidia has indeed decided to adopt this cooling approach for its RTX 40 series, then they will mirror what rival AMD has done in the past for its own GPUs – Team Red has already integrated triple fan coolers for some cards like the Radeon VII, in addition to designing specific cards with a liquid cooling solution such as the RX 6900XT LC and Fury X.

Ultimately, the RTX 4090 and the Ti variant will undoubtedly be absolutely massive video cards. The allegedly leaked RTX 4090 cooling heatsink shows how these units will likely require specific PC cases large enough to even install them.

Regarding the launch date of the RTX 40 series, Kopite7kimi now agrees with Wccftech sources who suggest an October launch as opposed to the previously announced mid-July introduction.
