You should buy a power supply that is more than 1000 watts so that it can handle everything such as cooler, lights, RAM, CPU, and so on. Although it is a decent starting point for many buyers

To power an RTX 4090 directly, you will require a power supply that features the new ATX 3.0/PCIe 5.0 native 16-pin power connector. It is possible to use a power supply from the previous generation, but it may not be adequate.
