Who needs more than 550 Watts really

There is more than one way to buy "affordable" hardware. You can buy new budget hardware or you can buy older used hardware. Imagine someone trying to decide between a new 2060 or a used 1080. The 1080 is actually faster in almost all cases. If someone buys a 3080 or 3090 a few years from now, used, it's not going to use any less power than it does today. All these mining cards will get dumped on the market eventually, and it will be an affordable hardware Christmas. But if you want to limit your options, again, more power to you. Not sure how many posts you need to make here claiming that your limited budget makes you prescient about the power consumption of future hardware.

I was just letting the other guy know the sucks thing was just a joke and I'm also using 550W. Not sure why you need to make so many posts shitting on other people's choices.

My 5900x/3090 regularly exceeds 600w on load, granted it's a loaded rig with 10x drives etc.but not overclocked apart from simply enabling PBO in the bios.In fact the impetus for my 850 rmx was my Antec TP 550w squealing under the load of my then 5820k/ 1080 ti system so most loaded rigs can use 750w easily these days.

I couldn't care less how many bad choices you make. My replies were more aimed at providing a different perspective for others who might read this thread looking for advice. I know tons of people who got burned in the long run going with a PSU that was not powerful enough. I can't think of anyone who ended up regretting buying a PSU that was too powerful. I felt that your assertion that there is a link between budget and power consumption isn't always applicable, especially for many on these forums, and I gave an example why.

My old 16 core machine would pull almost 600 watts from the wall just running prime95.
It has an EVGA 750watt PSU in it.

If you don't overclock and you are running mid tier hardware then you can definitely run 550w power supply.

5900x/3090 combo here pulls 600W alone, playing cyberpunk or watchdogs legion showed my gpu hit 470W draw. CPU will pull 178W at full load, avg 125-150w gaming. Toss in lights, fans, 4 hdd, 2x ssd, 2 m.2 and an AIO and 700W draw is practically a given. I ran a 2080ti sli prior so I saw 800W on my previous intel system.

I'm running 5800X and a factory-OC 3080, and my UPS regularly spikes to 550W+ load. I've got a 750W PSU as a result.

Also, PSUs are more efficient when not running at 100% load. Ideally if you are going to pull 500W load into your system you'd want a significantly larger PSU than that to keep closer to the peak efficiency point.

I have 3700X, 2080 Ti SLI OC for 3D Gaming with Custom Liquid Cooling, Dual-D5, bunch of fans & SSD with 1600W PSU. I wanted to upgrade to 5900X after Christmas, unfortunately it is sold out in my whole country.

When I bought my 1600W PSU with just one 2080 Ti and 2700X, I knew it is way overpowered. But if I bought just recommended PSU by Nvidia 650W, or even 750W, I would have to buy a new one for second 2080 Ti. And let's say that I wouldn't learn from my past mistake and I would have bought just 1000W. Because why not, it should be enough, right?
Well, Linus has already demonstrated, that 3090 SLI can trip over 1000W PSU. So for 3090 SLI I would once again have to buy new GPU. And next generation might be even more bloodthirsty.

Instead I bought 1600W model. And you can bet your ass that no matter what *gaming* CPU / GPU configuration comes in next few years, I won't be limited by my PSU. And I do plan to buy next-gen GPU, probably I will go for SLI if it will be available.

The EVGA power calculator came up with 567 watts for my PC (i7-7700K, RTX-3070, two M.2 SSDs). I went with a 700 watt Silverstone supply to be safe and allow for minor expansion if needed.

You're being mean to my 5950x.

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.
Nope, go look at the LTT Video today:
275W sustained on the new i9 CPU. Guess what? Your 5950 is probably pulling just as much if you push it full tilt.

A Shunt modded 2080 ti will pull north of 500 watts by its self under 100% load... It is better to buy what you need and add 20% capability to give yourself a little head room for expansion down the road.

Yeah but how many people will shunt mod their card? Truth is most people go way overboard on their PSU.

Conversely, why do people always want to cheap out on PSUs? The EVGA forum is filled with people trying to run 3080s overclocked on split connectors going to their 480w diablotek or whatever cheap ass psu ...
Easy, you don't get any performance improvements if you buy a 550W vs. a 1KW PSU. Either it works or it doesn't generally. Not excusing those dopes on the EVGA forums btw.

Ah, another person who believes car insurance is a scam. Gotcha. I too like to have my car cruising at full revs down a country road at 35 miles per hour. Why have all those extra gears anway.

You asked, I told you why. Not sure why you think I'd do that given my last sentence in that post.

A PC isn't all about performance. Having a singular goal like that is short sighted. That's what I'm saying. Sure, you don't need to spend $500 on a PSU. I have a 1300w platinum that I got for under $200. It has a ten year warranty. Now I don't have to buy a new power supply every single time I upgrade. I also have better components to protect the expensive performance oriented ones while giving me extra headroom for power draw for things like extra fans (also don't provide performance) and water pumps.

Most people can use a 750W and have no problems for 10 years. Power requirements haven't been increasing dramatically over the last several years or anything. If you feel the need to justify going way overboard with a 1.3KW PSU because you have 20 fans then good for you.

Last time I checked this was [H]ardocp not [L]impclockers. Either way with say a 2080ti and a 5900x just at stock you will be pulling over 500w total system load...
No shit, notice I never said you only need a 550W PSU and never anything more powerful.

But if I bought a 750w power supply I would have it maxed out and have no room for anything else. You sound like reddit right now. "Only build this!"
