You are on the wrong side of facks chickenballs, chill. Transients being able to down quality 850's have been a thing since the Vega line of GPU's on AMD and since the RTX3k line on Nvidia.
Flagships have needed 1kw PSU's for awhile now for real stability. Not saying you cant use less, but there will, inevitably, be eventual crashes (which will probably get blamed on something not at actual issue).
Keep in mind, Plus 80 mean nothing unless you read the reviews where PSUs was deeper reviewed. Plus 80 only proof efficient by power factor, nothing else for stability verification.
and I can provide credible sources for my claims

google?
also, im not going to run over and reinstall an 850w in the persons pc i was talking about earlier, just to not only hassle him, but make a nonsense video showing his pc crashing while playing games with a 850w and said crashing vanish from existence after replacing it with a 1000w , but also you might ask, why i chose this solution, well.. because its common information across the internet that crashing/shutdowns happen when a 4090 power spikes because of under powered psu's being used with them and the 850w being the common choice, through bad recommendations.
heck even newegg and its sellers are recommending 1000w psus for 4090's. well at least the ones i skimmed through earlier today.
anywho, not worth wasting time arguing over, google your proof.
what does 1080's or 2080's have to do with a 4090?
https://www.techpowerup.com/review/intel-core-i9-13900k/22.html
167W average in games at stock speed
287W in multi-threaded workloads
413W OC all core
nobody was talking about PSU ratings
This was a program running not cpu itself. As I said, CPU can't be inefficient because it is a power loading based on activities. Same true for power supply with load resistor.
uh yes....

1.50 frames per Watt at 1080p vs 4.1 frames per Watt for 5800X3D
im not the saying its inefficient here
if you have problem with that statement tell all the review sites like guru3d, Techpowerup or Anandtech
Do you see GTX (anything) or RTX2k in the above?...
You then linked to pre-release Press Release piece about all the Talking Nvidia was doing about their tech before anyone had their hands on it.
I will at least give you that techpowerup is a good source *but* not when they are parroting a pre-release PR piece, and also *not* when they as a pulication/company litterally lack the hardware needed to even test the claims they are parroting from NV.
To be clear, the 4090 is better about spikes than the 3090. But its still not great. Also to be clear spikes do *not* equate to normal/average power use, nor are you talking about the types of spikes you, me, or most anyone else can see.
In order to even be able to log/see these types of spikes you *have* to use scientific equipment, often to lab grade standards. There are only a handfull of review/publication sites world wide who are setup to actually test this stuff.

Watch here (&t=615s if it didnt time stamp right) and you can see the testing needed. You can also see that though its not as bad as people woried, the 4090 is not great either.
Point is, they days of 1KW psu's are here again.
https://www.digitaltrends.com/computing/the-decade-of-ignoring-your-gaming-pcs-power-supply-is-over/
hmm I wonder who said that
https://www.tomshardware.com/news/1200w-power-requirement-rtx-4090
I said that... Whats the point? Its accurate.
And we already covered the TPU lacks the ability to even test this stuff...
Again, why are you seemingly lacking the ability to understand all this? Go read up and educate yourself from some of the few publications that *can* test this stuff, I alreadly linked you a vid to one of them.
I'm not going to go lambast an otherwise good review site for having some somewhat incorrect views just because they lack the ability to accurately test the counter claims. Thats childish. The adult thing to do is to *understand* that there are *other* third party review publications that *do* have the equipment to test this stuff, and that for some specific cases (such as reviews of transient power spike impact on a user) going to one publication over the other is a wiser choice, as one knows what they are actually talking about from in house real world testing vs the other which is talking about theory or relaying told-to information.
Either that or go get your own oscilloscope and clamps and test it and prove it yourself. Otherwise have some respect for the professionals who have, and some grains of salt to the views of the publications who have not.
But one user to another, I can say I have seen the same things Jamesbonds and/or his friend have reported. I saw it with a quality 750 and my 4790k when I went to the Vega 64. Just like his bud, crashes under load etc. Was able to make it work by power limiting the card temp, but a 1kw solved it. My best bud, had a seasonic 850 with a 5600x/3060ti, went up to a 5800x3D and 7900xtx and thought he would be fine on his 850w. Was not, had crashes under load, fixed (temp) with power limit on GPU, fixed long term with 1kw PSU.
Its simple really.
and he has never said that 1000W psu is absolute minimum for a 4090 and powerdraw of the CPU doesn't matter which is what I have been trying to say. A decent 850W psu should be enough for 4090 and 5800X3D.
As the Tomshardware article clearly says that everyone has different rig and therefore different PSU requirement.
Your source with "Energy Efficiency" does not claimed made to CPU standalone, but based on CPU only of benchmark software.
If you have watt meter, then you will see power is lower at idle CPU and GPU.
