Hi guys, I'm planning for a build. The build I'm planning for is this: https://pcpartpicker.com/list/DB6vGq
For a build like this, 1000w is HUGELY Overkill, but I'm futureproofing my psu since I'll be buying on of the 30 series and a ryzen 9 in like 3-5 years so.... yeah. Also, what's the best and safest miner to use? This build is a gaming build, but at night I'll just leave it to mine, I live in the UAE btw so prices here are wonderful.

We can't know what's the best 1kW PSU under 250$ in UAE. Follow the link in my signature and pick the cheapest gold colored tier A unit available, maybe blue colored if they're considerably cheaper.
 
Really, there is no need for such overkill.
Even if money is no object.
Here is a good chart as to what is appropriate for different graphics cards.
It shows 400w for a GTX1650 super:

By using a psu capable of 1000w, it will use only the power demanded of it.
So far, so good.
But, a psu is most efficient in the middle third of it's range.
Your psu will be consuming more power than what it should running at much less than capacity.
Look for something in the 650/750w range to handle a future graphics upgrade.

Since it is a B550 motherboard with an AM4 socket, the Ryzen 5000 is probably the last series that will support that socket. This means the 5950x is the most powerful processor you will be able to use. So, even if you will take the 5950x and RTX 3090, the actual power consumption will be around 540W.

So buying a good 650W or even 750W will be more than enough for your final build and future upgrades (unless you will have more than one GPU). Note that power supplies have an efficiency curve. Using 1000W for 300W or even 550W PC will be very inefficient and may lead to higher energy costs.

Try to use this calculator: Power Supply Calculator - PSU Calculator | OuterVision with your final PC you want to build in 5 years (even a little bit stronger) and select a proper power supply.

I picked a b550m since it's cheap and plus I'll upgrade to ddr5 after it comes out by a year or two. Well most people said don't run a 3090 on a 750w psu, and the rm850x is more expensive than the rm1000x in my country, that's why I picked it.

Well I'm underage so I'm trying to get the best yet cheapest components. For example, I'm futureproofing the psu and most probably the case too so I want to spend as much money as possible later. If I buy a 140 dollar psu now, (750w one), then I found out it wasn't enough, then I have to spend another 200 bucks to get one that fits. In total that's 340 dollars. If I get one that's more than I need now and will fit later, I would have spent 200 bucks. Get my point?

That's why I sent you the PSU calculator - plan your PC for the future. Don't forget that you will pay more money for the electrical cost if the power supply works inefficiently... Yearly! (That calculator can also estimate the yearly cost)

I picked a b550m since it's cheap and plus I'll upgrade to ddr5 after it comes out by a year or two. Well most people said don't run a 3090 on a 750w psu, and the rm850x is more expensive than the rm1000x in my country, that's why I picked it.
Your motherboard has DDR4 slots. I doubt that DDR5 will fit...

And I don't know about people who said about 750w with 3090 and what their build. I don't have the 3090, but I see its specs. Ryzen 5000 uses less power than Intel ones, Ryzen 5950x with RTX 3090, and the rest of your build will take around 540W. High-end Intel CPU will take more than that - maybe around 610W. But it is not relevant... BTW, Nvidia recommends a 750W power supply for 3090...

Just calculate it with the calculator, enter all your components and your planned overclocking, and choose the best PSU for your build.

But the final decision is yours, of course.

Upgrading the motherboard to DDR5 sockets will probably have a different CPU socket, so you need to replace the CPU as well.

CPU + CPU cooler + motherboard + RAM is almost a new build...

So it's cpu and mobo and ram but that upgrade will happen in 2-3 years. Btw my setup with a 500w 80+ psu is around 108 dollars per year with monitor so the difference won't matter much with a 1000w one.

It depends also on the PSU efficiency type (80 Plus none, bronze, silver, ...) it determines the efficiency of the PSU. I would recommend at least 80 Plus Gold.

Yea the corsair rm1000x is a gold rated psu.
It depends... 5900x and 5950x for example, don't come with a cooler. From my experience, they need high-end cooling...
Well about that, I'll have a larger budget in the future to work with. I'll most probably not reach the ryzen 7 before I get ddr5. Maybe I'll get the ryzen 7 then the ryzen 9 I'll get ddr5 with it.

30-series GPU and Ryzen 9 CPU will work perfectly on a 700W PSU.

1000W PSUs are intended for multi-CPU, multi-GPU (3 or more GPU) systems. Totally not needed for desktop use. With dual-CPU or quad-CPU motherboards becoming more and more rare, and with SLI and Crossfire being virtually discontinued, then I would not be surprised to see the 1000W consumer-grade PSUs disappear from sale before too long, and we will only see server PSUs rated that high.

But like with anything in PCs, there is always a certain proportion of consumers who think "higher numbers = better". So I guess they are the ones keeping the 1000W PSUs on sale these days.

A 1000W PSU will still work of course, but seems very wasteful to me.

Some people say a 3090 with a 5950x shutdown sometimes, and if you tell me 850w, believe it or not, it's more expensive than the 1000w. Except if the RM850 is good and has a 10 year warranty, I'll get the 1000w. The rm850x costs 900 in my country, and the rm1000x costs 800. The RM850 costs 600.(the currency is AED)
