The more I learn about the 4x cards the less I want one.

yea i had to let a 3070 ti go by on ebay for about $380 after i found out last minute it was a 3 slot card and wouldnt fitalmost sounds like see what good deals pop up on ebay for a 3080/3070Ti/3070
That's what they said about the 3090 Ti too (both 450W cards)... my 850W and 12900K with it doesn't mind (nor did my 750W, however I wouldn't recommend it). If you're actually running this thing at 450W along with a CPU, I'd go no lower than 850W.Brando, the 4090 requires a 1kW PSU from what I have seen.
- Recommended Power Supply
1000W- Power Consumption
450W
Oh I know.. and as we all know, they tend to recommend higher than needed historically. Just sharing a real use case.I'm just referring to what is recommended by the card manufacturers.
Exactly what kind of power meter are you using? I would like one for myself.

Ironically, I'm running the same exact PSU on that setup. My power meter, for MY uses, peaked at 528W from the wall (gaming load).
Worth noting, the PCIe 5.0 plug is good for 600W... the 4090 card is spec'd at 450W. Board partners will raise that some, but not 33% more.Nvidia site is saying 850 w for the 4090 but I'm guessing all the other companies are pushing it to 600 w. Hopefully I can get a founders edition and keep my old power supply
sounds like they are being a bit conservative on the ratings. i dont know the exact pins vs the molex ones i talked about in the other thread. i would still assume something like 125 to 150 watts per set of pins. of course its best to under rate the spec so it doesn't overheat the cables/connectors for power.Worth noting, the PCIe 5.0 plug is good for 600W... the 4090 card is spec'd at 450W.

MSI's Suprim X (their flagship) lists an 850W PSU. Even the Suprim Liquid X recs an 850W PSU. Asus' 4090 Strix OC wants 1KW as does Gigabyte high-end models. Low end models will vary, so it just depends the card.
