First, they blew up my PSU:3080 FTW3 Ultra (XOC BIOS tested) Power from the wall numbers

Will depend a lot on the PSU - for instance I used to have a OCZ Fatal1ty 700 Watt PSU which used an Impervio design (manufactured by IS Quasar according to Google) - tested better than most 800 Watt units and someone long term stress tested its ability to do 900 Watt! as stable as an average 900 Watt unit.

Some OEM's are better than others. Generally the price dictates the quality of components inside. If your lucky you can have a solid OEM make something for like coolermaster/corsair.

That's a troll video. With B-Roll footage of RDR2.
No actual in game video showing his findings other then him making it to desktop. And I know why too.
The 450W PSU makes it to desktop but gives out when trying to do 3D stuff. The 600W PSU works just fine. I have no reason to doubt him and don't think he's trolling.That's a troll video. With B-Roll footage of RDR2.

100 watts of headroom isnt enough, asking a PSU to work at 85%+ capacity for extended periods wont do the PSU any favours. Not only that, but numbers measured at the wall dont reflect the real power draw of the cards because what you read at the wall is averaged across x amount of time. As measured by igors lab, a stock 3080 can break 500w at peak transients and you need a psu to deal with that as well as powering the rest of the system. I would want 30-40% headroom minimum and more if i was using a very power hungry GPU.
Like i said, *I* would want a kw because i know i'd be clocking the nuts off both the gpu and cpu. I would not be comfortable knowing a have a cpu drawing 220w and a gpu that can peak at 500w plus being powered by a 750w PSU. That is not at all an overkill assessment.
And that's a stock FE, not an overclocked FTW3 Ultra
That is correct, the power draw people see in apps like afterburner are not sensitive enough to pick up transient spikes - you may think your 3080 is cruising at 320w which actually it can be having 0.1ms little spikes up to 450w that you won't see in your monitoring software and then later you wonder why your 650w PSU blew up
That guy undervolts all his hardware - both that CPU and GPU will be significantly undervolted.

Hmm, 230K views, 11K likes. That's one of the biggest youtube video trolls I've seen in a long time. Rick Roll still tops it though. 
That’s interesting...

You could (but probably shouldn't) run two with one of those bad boys.Should be ok with my 1000w Superflower Platinum Leadex Psu i guess
A troll video from just about the most respected name in the SFF community? There's only one troll here.
OMG no hahaI'll run a 3080 on my 520W and let you know how it goes

I am 2/10 on the concern scale with my gold 750w Seasonic. A lesser brand I would be an 8/10. I was looking black friday deals on PSU as I dont mind relegating this one to the Backup/Server machine but the 850-1000w ones are well over hundred quid

My 3080FE pulls about 450W max if I up power limit and overclock according to GPU-Z. But I've undervolted it and running it around 1950Mhz. My whole system from the wall is using about 550W maximum - that's including the monitor, a Himalayan rock salt lamp as well.

ive tried two 3090's on my seasonic titanium 750w, i had power issues with both of them, had to give up and stick with a 3080 which has been fine so far, they are so marginal for these new cards though.

Lol, im watching Steve (gamer's nexus)'s recap of the RIPJAY/REPGN overclocking battle and he mentioned his 3090 was pulling 700 watts under ln2 at points. absolutely mental
I'm definetly going to undervolt as well. Been doing it with all the cards I've had over the past few years and have always been pleased with the results.
