A 3080 or 3090 graphics card can pull 300-400 watts when oveeclocked by itself. Many CPUs themselves can pull up to 200 watts or more when overclocked. A threadripper system can pull a magnitude more. Also your PSU shouldn’t be run over 80% capacity or it loses efficiency, (and as it ages encounter stability issues) so yeah there’s plenty of reason for over a 550 watt powersupply for an enthusiast overclocker. For a standard Dell or HP that isn’t overclocked so the CPU and GPU are running at rated TDP - a 550 watt would have plenty of headroom. Power draw depends on loadout, but overclocking quickly raises the requirements.There are so many power supplies over 550 Watts, but I wonder who really needs that, unless you have a quad SLI/Crossfire. I have 16 and 24 cores here and I'm fine with 550 Watts.
Cause people run stuff that is maybe more power demanding then a cheapo dell? Sure SLI/CF is not much of a thing nowadays but we have single GPUs that take as much if not more then old cards in SLI. The Nvidia Pascal cards were a anomaly. They were very efficient for the performance you got. I would assume the 30xx cards would also be a lot more efficient if they were on a better process nod then Samsung's.There are so many power supplies over 550 Watts, but I wonder who really needs that, unless you have a quad SLI/Crossfire.

I've had my 550W Kingwin Platinum (can do 650 Watts as Gold) for more than 10 years.Even if you don't need it now, how long do you plan to keep your PSU? Do you buy a new PSU every time you upgrade your motherboard+CPU and/or GPU? Otherwise how do you know how much you might need 5-15+ years from now? My current 1000w PSU is over 13 years old now, and still going strong. Turned out to be a great investment. If I had gone with something like a 650w instead because "that's all I need right now", I can almost guarantee that it would have already been replaced a long time ago. If you're one of those people who are super paranoid and junks any PSU more than 3 years old then you might as well stick with the 550.

1000 Watts isn't always good as it's less efficient at lower power draw.
LOL. Double barreled.
Efficiency is over rated. You not saving much not being in the curve.I've had my 550W Kingwin Platinum (can do 650 Watts as Gold) for more than 10 years.

ahahah ! I have my answer, people who need more than 550Watts are people buying top of the line video cards or overclocking 10+ cores CPU.
Mostly due to the video card.
As I said I got 2 computers here, 16 cores and 24 cores, no issue with power supply, both have 550 Watts, but they only have a RX-580

You do know how much you will need in the future because power consumption is related to how much you are willing to spend on the hobby.
Doesn't really matter though since anything that can be powered by 500W sucks.
You're being mean to my 5950x.
The GPU are what is taking high power mostly.
Fixed that for you. And yeah. You're being mean to my Palomino voodoo4 DDR system with 300w Fortron PSU. Damn fun. Think I'll go pay some more Quake2 GZ. Maybe some Red Faction and Max Payne too.Thays why we are no longer using a 300W PSU with a strong 5V rail from Socket A days.
Meanwhile PSUs haven't changed much in the last 10 years.

3080 and 3090 are power limited. Founders edition and "standard" for 3080 is 320, but quite a few cards ship with higher factory powerlimit, typically in the 340-370 range. They will not go over the powerlimit set so the peak you see when pushing the card is pretty close to max. For the 3090 is "standard" power limit is 350 while the higher end cards will be in the 370 to 420 range from factory. Increasing the power limit for overlclocking will give you a bit more, but only a few 3090 cards allow 450 or more. A modern intel CPU with a factory OC 3090 is probably the worst case "stock" though as it will gladly boost with 250 watts in the early stages for the CPU and add that to 420w for the 3090 and you can easily pull around 700 watts with just ram, cpu, motherboard and GPU.My 3090 has seen over 460W !!
Peak will probably be 50% or more higher.
Luckily PSUs also have peak power higher than rated but both RMS + peak drop with age and use.
A decently oversized PSU is needed if you value stability over the long term.
OP
You failed to consider your gfx card uses a lot more power than your CPU and can be easily beat.
I would never have run my 1080ti system with a 550W, simple sense.
If you dont do much with your PC you might get away with less.
Yes, my power limit is higher3080 and 3090 are power limited.

And I'll get a ThreadRipper zen3 when they are out and I'll be fine with 550 Watts. The GPU are what is taking high power mostly.
I'm using a 550W as well for the reasons mentioned. I'm not dropping $1000 on a CPU or GPU that will pull big wattage, so I already know how much I will need in the future.
I don't think affordable hardware will get too power hungry as well since manufacturers are also under the pressure to be "green". Not just for environment but cost as well.
