There have been many concerns about the power consumption of RTX 40-Series GPUs. Nvidia spoke up on the matter.
The new Nvidia GeForce RTX 40 lineup includes some of the most power-hungry graphics cards on the market. Because of that, you may be wondering if you’ll need a new power supply (PSU) in order to support the borderline monstrous capabilities of the RTX 4090.
To answer some of these concerns, Nvidia released new information about the power consumption of its new GPUs. The conclusion? Well, it’s really not all that bad after all.
Prior to the official announcement of the RTX 40-series, the cards have been the subject of much power-related speculation. The flagship RTX 4090 received the most coverage of all, with many rumors pointing toward insane requirements along the lines of 800-900W. Fortunately, we now know that those rumors weren’t true.
The RTX 4090 has a TGP of 450W, the same as the RTX 3090 Ti, and calls for a minimum 850W PSU. The RTX 4080 16GB takes things down a few notches with a 320W TGP and a 750W power supply.
