NVIDIA’s next-gen RTX 40 series lineup will be fabbed on TSMC’s 5nm node. This will, however, not prevent the GPUs from reaching a record power draw of up to 600W. As per a tweet from Greymon55, the top-end “Ada Lovelace” offering will feature over 15,000 cores and require a 1200W power supply for optimum operation. The tipster wasn’t clear on which SKU would draw up to 600W of power, but it’ll likely be the RTX 4090 or the RTX 4090 Ti.
Speaking of the RTX 4090 Ti, its predecessor the 3090 Ti will have a TDP of nearly 500W for custom AIB models. The MSI GeForce RTX 3090 Ti SUPRIM X with its 10752 shaders is capable of pushing 1,900 MHz in Extreme Mode. This results in a TDP of 480W, 30W more than the GeForce RTX 3090 SUPRIM X. MSI recommends a 1,000W PSU for the GPU.
The RTX 3090 Ti Suprim X will be powered by three 8-pin power connectors in contrast to the RTX 3090 Ti FE’s PCIe Gen 5 power connector. The ASUS ROG Thor 1000W PSU comes with 12-pin power connectors which are what you’ll likely need (ideally) for the RTX 4080, 4080 Ti, 4090, and the 4090 Ti. As per Kopite7kimi, 12-pin and 4-pin power connectors can together supply up to 600W of power which is exactly what the higher-end RTX 40 series SKUs will need.
