NVIDIA GeForce RTX 4080 latest: 320W power, previously rumored at 420W

NVIDIA's next-gen GeForce RTX 4080 graphics card is rumored to use up to 320W of power, which is down considerably from the previously rumored 420W of power.

The news on NVIDIA's next-gen Ada Lovelace GPU-powered GeForce RTX 4080 is from leaker "kopite7kimi" who tweeted: "We can expect RTX 4080 with 320W and RTX 4070 with 285W". The previous rumor for the RTX 4080 is that it would use 420W, so the drop to 320W is a lofty 100W... and that's a great thing.

NVIDIA has an additional 100W of power it can use for some monster overclocking on custom GeForce RTX 4080 graphics cards, something kopite7kimi addressed in a follow-up tweet, by saying: "Not much. The original power consumption limit is too loose which means great overclocking potential".
