Nvidia Clears the Air on GeForce RTX 40-series Power Requirements

Posted on



One of the biggest questions surrounding Nvidia’s GeForce RTX 40-series (Ada Lovelace) graphics cards is whether you need to upgrade your power supply. Nvidia has uploaded a new FAQ (opens in new tab) that sheds some light on Ada’s power requirements for future adopters.

Consumers won’t need to upgrade their power supplies if the capacity meets Nvidia’s wattage recommendations. The GeForce RTX 4090 has a 450W TGP, meaning you need at least a 850W unit. The GeForce RTX 4080 12GB (285W) requires a 700W power supply while the GeForce RTX 4080 16GB (320W) will need a 750W unit.
