If you dont mind the price the Seasonic Prime or the Be Quiet Dark Power 12 are options

 

XG850 Plus is even very quiet and much quieter than RMx 2021?

 

Which one is quieter? Seasonic Focus GX 850W Gold or Thermaltake Toughpower GF1 850W Gold? And overally better?

 

The Thermaltake Toughpower GF1 is not bad but i would not touch it with a 10 feet barge pole

 

I am with @shilka with this one , BeQuiet Dark Power Pro 12 is your best bet, it,s very quiet and titanium certified.

 

For idle it's totally silent, fan kicks in over 400+W load at "normal temps" https://www.tomshardware.com/reviews/corsair-rm850x-2021-power-supply-review/2

 

Sadly, Dark Power 12 850W is nowhere in stock from my suppliers.
I have 5800x with RTX3080 12GB so my power draw is around 600W and probably there is a hearable noise from many Power supplies.
It looks Also Seasonic FOCUS GX 850W starts to be audible from 500W and above...

 

You've shunt modded the 3080?

 

I can turn on the fan in my RM850x with OCCT power test with a 380W vbios so it's slightly audible above my <400rpm ML fans.
It also turns on with Port Royal but I can't hear it, had to check with a flashlight.
Normal gaming I've never heard it turn on.



But, yea it's a corsair ML fan so at high rpm it will get quite noisy. (I know this from my other ML fans )

 

My rm1000x isn’t noisy at all.

 

There are no reviews that i have seen that have done any load testing of the XG850 so you should not touch it with a barge pole
If it was good CM would have sent a review sample to Aris for testing so the lack of reviews leaves doubt about how good it is

The titanium rating has nothing to do with how good it is and any sort of quality just look at some of the SilverStone Stride Titanium models which are total rubbish

Edit: after digging around i found that the OEM for the GX850 is one called Huizhou Xin Hui Yuan Tech (Fusion Power) which i have never heard of before
Going by the name its probably one from mainland China

They did send one to Aris, he reviewed it for his certification body (Cybenetics):

Cybenetics Labs – PSU Efficiency & Noise Level Certifications

www.cybenetics.com

last on the list. he's also reviewed the 650w on his new website:

Cooler Master XG Series Platinum 650 Review - Hardware Busters

Hardware Busters - Cooler Master XG Series Platinum 650 Review -

hwbusters.com

TLDR it's one of the best PSUs ever made xD

@smoke2 XG850 is slightly better than the Fractal Ion+ 2, you won't regret buying one.

 

So according to hwbusters review you recommend XG more than Ion+ 2?

 

If its cheaper than i dont see the reason why you should pay more
Its less about what is better than the price in this case both of them are very good

However i believe Fractal Design is much much better when it comes to RMA than Cooler Master is so if you care about that you might want the Ion instead
I dont know where you are from and what local consumer laws you have

 

If you have case fans and GPU fans those are going to make way more noise than the PSU ever will at higher loads which means what you are asking is not really that important if everything else in the system is way louder

Almost every single mid range and higher PSU on the market has a zero fan mode which means that the fan in the PSU wont spin at all untill the temps or load goes high enough
I am pretty sure you wont be able to hear the PSU over the GPU and case fans at really high loads unless you pick a PSU that is super loud

Youre right.
Here is Seasonic Focus GX-850 for 120€. Its the cheapest Gold PSU.
Then Corsair RM850x 2021 costs 164€.
Fractal Ion+ 2 costs 182€
XPG Core Reactor is for 130€.
CM XG850 is for 174€.
Corsair HX850 185€.
Please, which one you will take? Is the best quality?
Thank you.

 

Seasonic prime has a silent option and some of the lowest transient response in the industry. Highly recommended.

 

My 2 cents worth I would not go any lower than 1000 watts especially for that power hungry GPU. but if you want go 850 is your choice good Sir. I like have extra power aside just in case of upgrade.

 

Need quick advice.
Asus ROG Strix 850W for 150€ or Fractal Ion+ 2 860W for 180€?
Both should be equally very silent...

 

@smoke2

You should consider moving up to 1kW due to high transient spikes of RTX 3000 cards. RTX 3080 will easily shoot up to, and over, 500W without any overclocking which can cause problems. See GamersNexus video on it here:

Edit For clarification this isn't an Nvidia only problem, it's just seen on more of their GPUs than AMD. For The Red Team it is primarily seen in the RX 6900/6950. The GN video also specifically points out people with 850W PSUs having problems.

It's also worth considering a higher power unit for use further down the line considering how long you held onto your Corsair. We can only speculate on what future CPUs and GPUs will draw, but IMO the 'silicon wars' are fully underway with hot competition between Intel, AMD and Nvidia. They are pulling out the stops with products that draw more power than nearly anything that's ever been seen in the consumer space.

You can also check out Igor's Lab for transient spike information, but you'll need to translate to English.

One of the best places to go for PSU reviews is going to be Cybenetics Labs: Cybenetics Labs – PSU Efficiency & Noise Level Certifications - Power Supplies

That's a link to their PSU review database which presently has 548 units in it. They verify 80+ certifications and also do extensive noise testing. You can look at PSU units by their verified 80+ cert, or by how quiet Cybenetics has determined the units to be. Each unit has an extensive report generated telling you, literally everything, about the PSU down to the types/model numbers of individual components that make up the PSU.

I just grabbed a Phanteks Amp 650W, a customized Seasonic design, for my HTPC due to their findings on how quiet it is even while under load.

Honestly, it looks like to me now, with the new generations of CPUs and GPUs performance increase in these days is going hand in hand with higher power draw.
Maybe the 1000W unit could be adequate also on the background of broking RM750x after 6 years with year spent with RTX 3080.

 

Sent you a PM Smoke2.

One discussion which isn't really able to be had yet is the new specification for PC power that will change the connectivity and power rails required by PSU's. There will surely be a transition period, but more efficient and capable PSU's will appear once that change occurs as much of the power conversion circuitry will be removed from the PSU and occur digitally on the motherboard.

 

I have fractal ion 860w (1st gen) and its very noisy ,even on idle . Its driving me crazy ,I can hear it all the time over my 13 case fans (7x noctua 12x25 + 6x arctic p12) .

 

I have fractal ion 860w (1st gen) and its very noisy, even on idle

That might be worth talking with Fractal support about. Unless something with the case is increasing noise, the Ion+ 860W should be pretty decent below 650–700 W. Even the Ion 850W ought to be ok up to somewhat over 500 W.

 

So overally its good to take 1000W RMx and paid 25€ more than take 850W RMx if Im planning to buy RTX 4080?

 

The 4080 does not even had a confirmed power draw yet it changes almost every single day
Maybe wait and see before you go out and buy a new PSU just to find that maybe its not big enough

 

But I need it now. Do you think its worth to spend 159€ for 1000W instead of 133€ for 850W?

 

Do you think its worth to spend 159€ for 1000W instead of 133€ for 850W?

Mostly answered this on the first page of the thread but, if the rumored upper end of the 4080 doesn't leave your power budget with some indication for supplies above 1000W, that's probably worth a closer look.

The prevailing expectation seems to be 40 series AIBs will be back compatible with ATX 2.n supplies. Given your concern over 26€ and the amount of 3080 and 3090 problems with that configuration it's probably also worth doing some thinking on how big of a bet you want to make.

 

Buy a 1000 watt PSU in this case if you dont mind the extra cost its better to have the wattage and not need it than not having it and needing it
