With the new generation Nvidia GeForce RTX 40 Series graphics cards coming soon, wattage and power supplies (PSU) are major talking points.

After all, as technology improves, more and more power is often needed to get the most out of new hardware. The Nvidia GeForce RTX 40 Series graphics cards boast an impressive TDP overall.

The RTX 4090 sits at 450W while the RTX 4080 16 GB and RTX 4080 12 GB have a TDP of 320W and 285W, respectively. As far as PSU recommendations go, Nvidia recommends a 850W for the 4090, 750W for the 4080 16GB, and a 700W for the 4080 12GB.

Other partners like ZOTAC, however, suggest you’ll need a 1000W+ PSU for the custom overclocked RTX 4090 partner models. While wattage is one thing, the physical connection to the power supply is a whole different story.
