Nvidia's upcoming GeForce RTX 40 series cards are likely to exist the company'due south nearly powerful GPUs yet. Given that these GPUs reportedly deliver double the operation of the RTX thirty series, we expect them to be power-hungry cards. Recent leaks reveal this to be the example, as the highest-end RTX twoscore series card may require a massive 1,200-watt power supply unit.

As NotebookCheck reports, known leaker "harukaze5719" was on Twitter commenting about Nvidia'southward Lovelace boards (Lovelace being the codename we believe Nvidia to exist using for its forty series cards) and Intel'due south Raptor Lake CPUs. The user said: "Expecting i9-13900K + RTX 4090 Ti recommend PSU at least 1,000 W GOLD."

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

Greymon55 is a regular leaker who has previously posted details of what they claim nosotros should expect from Nvidia Lovelace. The user has stated that Lovelace boards would offer "double functioning" 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 upwards to 18,432 CUDA cores (the RTX 3090 has 10,496). A card like that would need some serious juice, and Greymon believes information technology will be 600W for either the GeForce RTX 4090 or RTX 4090 Ti -- though they noted that such an estimate was for a reference menu from Nvidia, not a custom carte from a third-party manufacturer like Asus.

Another leak reported past Digital Trends lends credence to the supposed i,200W PSU needed for the RTX 40 serial. The leak in question indicates that the upcoming Nvidia RTX 3090 Ti has a TDP (thermal pattern ability, often used as a measurement of power demand) of 480W, which would crave a minimum of one,000 PSU.

If the RTX xl series cards do indeed deliver double the operation of their predecessors then it's not so surprising that the top-end menu will consume a lot of power. If you lot want an RTX 4090 or RTX 4090 Ti, y'all'll need to be sure you take a power supply that tin handle them.

As I opined in a recent editorial, I can't get excited nearly Nvidia GeForce RTX 40 series cards. After all, it's all but impossible to purchase the electric current RTX 30 series cheers to the ongoing scrap shortage (not to mention scalpers). Reports say the semiconductor shortage could last through 2023. This means the RTX 40 series cards will no dubiousness be as difficult to procure as their RTX xxx predecessors.
