Nvidia explains what you need to know about RTX 4000 GPU power demands

Nvidia has clarified the situation around its RTX 4000 graphics cards and their demands on the power supply front, after what Team Green described as an “uptick in questions” regarding compatibility with the incoming next-gen GPUs.

And the short answer for those worrying that they might need to buy a new power supply for compatibility in an outright sense is that they needn’t worry – it’s not necessary to have a new ATX 3.0 model with PCIe 5.0 power connectors (known as 12VHPWR ).
