I need advice.
I have to buy a power supply, but I'm confused.
corsair rm850i or rm850x v2 2018 is it better?
Or be quiet dark pro 11 750w ?
I had decided stright power 11 850w platinum but I saw that they have a problem with incorrectly configured protection features.
what is your advice ?
Thank you
 
I would go with the RM850x unless you have other components that can use the Corsair i functionality. Other PSUs to look at are the Seasonic Focus GX or PX. Why do you need an 850W PSU though? That is way over what most people ever need.

my current configuration does not need more than 500w
but I want to think about the future.
I doubt two video cards
Rather an i9, 10 generation that requires 165 or 195 watts
I am a Linux user, the computer is more of a home server, i'm not a gamer

Even using that setup you don't need 850W PSU. These PSU calculators assume that you are running everything at full power all at once as well. Actual usage will be quite a bit less.

example rtx 2080 requires 650 watts recommended + 165 for i9 10 generation, ssd, fans and others
That's why I think 850 watts is enough at this stage.
I want to get a quality and quiet power supply.
That's why I hesitate between be quiet dark pro and corsair rmi
The question is: corsair rmi or rmx v2 2018 or be quiet dark pro ?

The RTX 2080 itself doesn't require 650 watts to run, that's recommended for an entire system that uses an RTX 2080. And they're very liberal with those requirements because of the inevitability that people will use garbage PSUs.

The RTX 2080 peaks in the 250W range.

My main PC runs a 2080 Super with a mild overclock (already with a higher wattage than a 2080), an 8700k on an all-core 5.0 GHz, eight hard drives, four sticks of RAM, a ton of unicorn vomit, including a custom RGB backplate. It's literally only off when it's rebooting or there's a power outage. I have the proper tools to monitor wattage and I've never come near 650W, let alone 850W.

The 2080 doesn't require a 650W PSU, that is just the manufacturers recommendation. Now when you use an i9-10900K with it you will want a 650W PSU. However, if you were to go to a Ryzen 3700X you could use a 550W PSU due to the lower power CPU & not needing a 280mm+ AIO.

What country are you in? Here in the USA PSUs are VERY expensive even for garbage so the good ones are even more expensive.
Bulgaria
dark pro 750 is about 205 euros 850 about 225 euros corsair rm850i about 200 euros
as a person from america, would you recommend a corsair I guess?
 
Dark Power Pro 11 is better than the Straight Power 11. The Corsair RMi & RMx are basically the same unit just the RMi has monitoring software with it. Quality wise the Corsair and Be Quiet are both going to be very good. I would also look and see how much a Seasonic Focus GX/PX or Prime GX/PX run. The Seasonic PSUs are also very good. One other alternative that is more inline with the Straight Power 11 in performance is the Fractal Design Ion+ in Platinum efficiency.

stright power also has problems with incorrectly configured protection features.
rmx has no fdb fan

Dark Power has higher efficiency but build quality will be equal. The biggest issue with the Dark Power is that its platform was designed 5 years ago so it may or may not have the absolute newest C state compatibility.
it is strange that Germany is closer to me, and be quiet is more expensive

If you are looking at spending 200+ Euros on a 850W PSU in which you won't need 850W, get a 650W Seasonic Prime TX for 200 Euro instead. Otherwise the 650W Seasonic Focus PX for 130 Euro is a good deal as is the 650W Seasonic Focus GX for 105 Euros. If you decide that you want more watts, even though you won't need them, the 750W versions are still far more affordable than the RMi or Dark Power Pro. Note that the Prime TX is one of the absolute best PSUs available and the Focus line are very good as well. Build quality on the Seasonics will be as good as Be Quiet or Corsair too.
