NVIDIA 4000 Series


My 4090 runs off my 750 W psu, so 850 should be fine.

A quality 850w is perfectly fine, Been running mine since release day from a Seasonic 850w and with a power meter attached to the wall and benching the GPU with different tests in 3d Mark coupled with a 12900k I never saw the highest consumption go over a 718w spike.

Not sure a 750w is sufficient if a CPU was stressed at the same time though but chances are it would probably be fine in gaming.

The only way to get it higher than what I saw is if you was flatlining the GPU and a power hungry CPU at the same time.
 
What prices, link?

Its a Seasonic Ultra Titanium, sure it'll be fine. Power meter hasn't gone about 680w yet. I have an HX1500i, but I'm testing to see how a good quality 750w will do.
