There’s a new rumour about the future RTX 5090, which could well arrive this year. According to Tweaktown, the card will require two 12VHPWR connectors for its power supply. This would allow the card to gobble up up to 1200W of power.
Up to 1200W of power consumption for the RTX 5090?
Obviously, when we learn that the future 5090 could be equipped with two 12VHPWR connectors, we get scared… Especially if we consider that these connectors would be 600W versions. Coupled, just with power supply output alone, the graphics card could draw up to 1200W of power, which is quite simply colossal. And that’s not counting the 75W delivered by the motherboard’s PCIe slot, or even more with the additional PCIe slots that seem to be appearing on more and more cards.
Don’t worry, it’s highly unlikely that the card alone will reach 1200W of power, clearly not. However, we can imagine that NVIDIA has learned lessons from its current RTX 4090 with the many cards that have burnt out because of this connector. By equipping its future card with two of them, you can then spread the load and avoid overheating. This is just a hypothesis.
Whatever the case, you’ll almost certainly need to use an adaptor supplied in the card box. Yes, power supplies offering two serial connectors are still rare. There’s certainly the recently released PX 2200 and Cooler Master’s X Mighty in 2800W, but it’s not the norm and it’s only reserved for a few very high-powered units.
