Nvidia's upcoming GeForce RTX forty series cards are likely to be the company's most powerful GPUs yet. Given that these GPUs reportedly deliver double the performance of the RTX thirty series, we expect them to be power-hungry cards. Recent leaks reveal this to be the case, as the highest-finish RTX 40 series card may crave a massive 1,200-watt power supply unit of measurement.

As NotebookCheck reports, known leaker "harukaze5719" was on Twitter commenting about Nvidia's Lovelace boards (Lovelace being the codename nosotros believe Nvidia to be using for its 40 serial cards) and Intel's Raptor Lake CPUs. The user said: "Expecting i9-13900K + RTX 4090 Ti recommend PSU at least 1,000 Westward Aureate."

Known leaker "Greymon55" soon joined the conversation and said that 1,000W "is not enough."

Greymon55 is a regular leaker who has previously posted details of what they claim we should wait from Nvidia Lovelace. The user has stated that Lovelace boards would offer "double performance" over the RTX 3090, and that lines up with rumors we've heard that the Nvidia GeForce RTX 40 serial has some killer specs, including upwardly to 18,432 CUDA cores (the RTX 3090 has 10,496). A card like that would demand some serious juice, and Greymon believes it will be 600W for either the GeForce RTX 4090 or RTX 4090 Ti -- though they noted that such an guess was for a reference card from Nvidia, non a custom carte du jour from a third-political party manufacturer similar Asus.

Some other leak reported by Digital Trends lends acceptance to the supposed 1,200W PSU needed for the RTX forty series. The leak in question indicates that the upcoming Nvidia RTX 3090 Ti has a TDP (thermal design power, often used as a measurement of power need) of 480W, which would crave a minimum of 1,000 PSU.

If the RTX 40 series cards do indeed deliver double the performance of their predecessors then it's not and then surprising that the top-end card will swallow a lot of ability. If you desire an RTX 4090 or RTX 4090 Ti, you'll demand to exist certain you lot have a ability supply that can handle them.

As I opined in a recent editorial, I tin can't get excited about Nvidia GeForce RTX twoscore series cards. Later on all, information technology'due south all but impossible to purchase the current RTX 30 series thanks to the ongoing chip shortage (not to mention scalpers). Reports say the semiconductor shortage could concluding through 2023. This means the RTX twoscore serial cards will no uncertainty be as difficult to procure equally their RTX 30 predecessors.
