I'd go for the Corsair.

 

Why would you need 850W though? It's a waste of money likely...

It's not a waste of money if silence is priority. For example if fan starts at 40% load,it will not even start if it's high wattage,see the point?

You have no idea what you are talking about and its total bullshit because it violates the laws of thermodynamics!

 

With about the same load and the same heatsinks and efficiency, the heat generated is the same. But the Heatsinks of the 850W and 550W Corsair RMx (2018 Version) are the same, no difference there...

 

And the 40% are just a guesstimate for people who don't know much about Electronics. 

 

In short:
It is more probable to make a very quiet 550W PSUI than an 850W.

 

But hey, ~500rpm with a decent fan is hella loud!111

So, no, if you want a quiet PSU, you get a quiet PSU.

Moar wattage does not mean more quiet, it just means more watt and more often than not is not quieter.

 

 

So it would be nice if you tell people, when asked why you want it, than to claim some nonsense like this fairy tale.

see the point?

No, because its not true.

 

A PSU is not an engine.

Relative load does not matter, as I said earlier, absolute load does.

So if it is loaded to 30% or 60% is irrelevant, if the load is 30W or 300W is not.

 

 

And some people here are very interested in PSU for almost 10 years, some worke or worked in the industry...

First off all,calm down. 

Secondly, I've already written to you that 650/750/850 differ in 10-20$,so I don't care about that and if I decide to sli I don't want to change psu,all I care about is silent operation and enough power for future proof.

Yes and no, on LLC units you are correct, on older double forward based units relative load may have a small, yes noticeable, effect on efficiency which in turn affects required cooling.

Stefan Payne can get a bit carried away in his wording, lol. But what he says is true. 

 

You never mentioned before that you might plan to run SLI, so that would have been useful information in helping us make a recommendation and in answering your question fully and thoroughly. The more info you give us the better. We're just trying to help you potentially save money and help you choose the best option for your situation. 

 

As someone who has tried multi-gpu setup before, I can tell you it's not worth it. The only really useful thing SLI/CF has going for it is getting high scores in benchmarking.

Yes I understand that clearly,but I asked simpliest question in world: which psu to take from this two variants? I didn't asked how big psu I need or what will I need in future,will I do sli or not etc. All I asked about choice between the two And as I said with difference 10-20$ I will always take 200-300w bigger psu,just let me be happy with my choice.

unless were talking about a PSU that has a fan less mode like the RM in which case it can.

how can i tell what a grey unit is (is it the sticker on the side), and what is the difference btw these two

It refers to the sticker, yes.

Get whatevers cheaper; the 2018 and older version is electrically the same.

tnx, can you check this 

 

i have few to choose from, and i really dont know which one of them is best price/performance buy

Oh so now Semi Fanless can violate the laws of thermodynamics??

How come?

Why do you think that??

[Branford]

Hello guys! Im having a problem, I guess that my PSU or some of the cables could be have some issue, anyway, I have a cheap Tacens Mars Gaming 650W (no certificate) PSU. When playing some heavy graphic games... looks like my GPU doesnt get all the energy it needs in that moment and boom! GPU fans throtle 100%, no signal on screen and I have to do a buttom reset, wich I hate.

My spects are:

Zotac 1070 8Gb
i5 6500 (but I will use a i7 6700k soon)
16 gb ram DD4 (dual channel)
1 SSD 120GB
1 7200 rpm HDD
gigabyte ga-h110m-s2h

So I guess I have to buy a new PSU, so I want to know if I can go for  EVGA BQ 750W for example, I wont do any OC.

thanks.

When the fan does come on (which it will when you're gaming), it'll be louder than the fan in a good lower wattage unit because they tend to use more aggressive fan curves on the higher wattage units.

By all means, you can do what you want, it's just not necessary to do that and you'd have a quieter PC by choosing a quieter PSU (than the two options you asked about). That's all we're saying.

Buy a lower wattage high quality PSU, like 550W SeaSonic Focus instead. That PC uses under 450W when heavily OCed.

Thanks! Well I cannot find any seasonic on my online store but I saw they hace a EVGA Supernova G3 550w modular, you think I won’t have that issues I’m having? I mean, you guess 550w is enough for my system? (Remember that I’ll install an i7 6700k this week... I don’t want to be short on power, sorry I need help because I’m not good on PSU’s.

 

Thanks for the help

Even a 8700K and GTX 1080 Ti bundle would work on 450W. You'll be fine.

Ok thanks for your answer mate, that really helps me a lot! Trust me, so the one I told you before is good enough? The EVGA Supernova G3 550W Modular? That one is ok?

For the system you listed (not the one in your sig), and since you mentioned silence was a priority, any of the following should be good: BeQuiet Straight Power 11, Bitfenix Whisper, Corsair RMX all in the 550w range. 

 

Give SLI some serious thought. The reason I say that is because I really wanted to try a few years back. It was fun for a short while and then I realized it wasn't so great and I was lucky to get my money back out of it. Went back to a single GPU and never looked back. If, however, it's still something you think you really would want to do, then go for something in the 750w range, that would be plenty.

Yeah, mGPU doesn't even work most of the times.

With the games I like to play it does not work, for example NIER:Automata (wich I had to play with the HD7970 at the time).

 

And I highly discourage it because of all the issues. If you only play american AAA titles like Call of Duty, Battlefield and co, it might work for you. But if you take just one tiny step outside this range, it all breaks and you are in for a world of hurt...

 

Yeah, its that bad. µStuttering is the best that can happen, at worst you have a second card that does nothing but is there and consumes power...

Can any one tell me how an Antec Neo Eco 650M Be for my system? (8700k+1070ti)

 

Can't find any decent Tier 1 or 2 (that is not over 850w) PSUs anywhere where I am from  

 

Thank you

Should be fine, IMO. 

[Tamago_Sushi]

between Corsair RM750i and EVGA G+ 750w

which would you guys recommend? 

I could fork out the extra bit for RM750i, just am kinda new to psu

Depends on what Version you have but it looks like it does not regulate 5V and 12V independently from each other, so you should look to replace it.

NOT the EVGA.

 

Any other Options? be quiet Straight Power 11, Bitfenix Formula, Whisper M, Cougar GX-F?

My local store doesn't have a lot of options to be honest.. ( Im living in Malaysia ) 

 

EVGA, Silverstone, Cooler Master, Superflower, Thermaltake and Corsair. Thats what they have. 

Superflower left with 650w Leadex ( not sure 1 or 2 ), Corsair left with rm750i, hx1200 and cx850m, Cooler Master I didn't ask yet, Silverstone they offered me the 650w Plat but not sure if they have other options or not, Thermaltake I didn't ask as well.
