hey guys, do you guys have any information on this pretty much after my research and after several posts here reading your advices my choice was to buy corsair rmx1000 w 2018 version but now i cant find it for more then 20 days in stock anywhere in my country...
during my research last month it was in stock in 4-5 shops but back then i wasnt sure what to buy.
i dont want to buy 2021 version because i read the review here and also saw the cybenatics dbm lvls between the 2018 and 2021 releases and pretty much the 2018 is close to 10 dbm less in sound levels output then the 2021.
for me the sound lvls is the most deciding factor about which psu to buy. and from what i saw 2018 corsair rmx1000w wins by a lot when compared to lets saw the newer version from 2021 or the seasonix gx 1000w gold or be quiet str. power 11 1000w gold.
even though the seasonix gx is 30 euro cheaper in price then the 2018 corsair rmx i saw that between their fans the corsair rmx fan is also more preffered then the seasonic gx one. because from what i read ppl say the seasonix gx fan has bigger chances to show some problems in general during high loading times then the corsair rmx fan [when talking about sound lvls during its work.]

now i wait for more then 20 days in hope corsair rmx1000w 2018 to come back in stock but i am almost giving up.
so i wanted to ask you guys is there any information if corsair stop production of the 2018 rmx 1000w power supplies due to focusing now on making only the 2021 version psu.
or they still making them so there is hope for me to wait a bit more to get one.

and the last thing did corsair fix the more agressive fan noise output lvls from the 2021 version rmx1000w psu in such way that it is now close to the top of the line dbm sound noise lvls output of the older 2018 version. or since the review of the 2021 version here on toms they didnt touch it.
i am asking this because if they touch it and the 2021 has now been reworked and got close to same dbm levels of the 2018 version i will not wait and just go buy the newest version.
interesting part is that the corsair rm850x gold 2018 psu can still be found in the shops here but not the 1000w from 2018. but i just dont want to buy the 850w because i want to a bit bigger space when i upgrade my system build in the next years in the face of me not in need to change the psu with new one after 3-4 years. those 150 w man .... dam ...

There are no RM1000x 2018, the only 1000W RM-x are 2015 and 2021. What are your PC specs that you need a 1kW PSU and concerned about the noise at >70% load where there would be any difference with 2021 version over 2015/2018 ?

my gpu is sapphire radeon rx 590 nitro plus 2x8 ram cpu is ryzen 7 2700x got 2 case fans and motherboard is asus tuf gaming plus 570

i know 1000w is overkill for the current build, but i think you will agree with me in 3-4 years when i upgrade to something much more power hungry 1000w psu will be resonable investment now in order for me not to buy new psu aswell in the future.

in previous talks here with you guys i end up with the mindset that since i want the most silent psu possible for my budget witch is about 150-175 euro from the current market in bulgaria the corsair rmx 1000w gold is the best choice since its 1000w and it is more silent on its dbm output then seasonix gx1000 gold according to cybenetics statistic. also i was asking you too and you told me that in general the fan of corsair rmx historicly is more reliable then the seasonic gx one. so if this is the case still i am leaning towards corsair rmx. problem is when i was making the research and gathering info the market had some of them in stock - 1 days after when i wanted to order they siddenly went ghost.

to start word by word answering on what you said and if i am getting all of it right you said rmx1000w is only 2015 2021 versions. - i was thinking that since there is
Corsair RMx Series RM850x 2018 850W Gold (CP-9020180) 2018 version

there should be rmx 1000w version 2018 aswell ... / is this not 2018
Corsair RMx Series RM1000x 1000W Gold (CP-9020094)
[ i dont rlly get those numbers right and i got no idea also where to check which year they are manifactored.]

so to clear this out of the way you are telling me there is no 1000w rmx corsair 2018 version but there is only 850w corsair rmx 2018 version is this right and thanks in advance for it.

about the last part of what you said - [QUOTE What are your PC specs that you need a 1kW PSU and concerned about the noise at >70% load where there would be any difference with 2021 version over 2015/2018 ?
[/QUOTE]

from what i saw on the reviews here and on cybenetics stats about the noise levels of 2018 2021 of the corsair rmx 1000w and even on the 2018/2021versions of the corsair rmx850 gold the 2018 versions are definatly more silent with about 10 dbm less outout then the 2021 release even the review states it is due to some extent to the more aggressive fan ... i know you are right when saying under 70 percent load there will be no such a big difference in the noise lvls between both versions but for me its about those differences when we talk over the 70 percent load and if it is 10 dbm plus or minus difference between 2018 and 2021 in favor for the 2018 version psu with its fan then it is winner for me.

from what i read the 2018 rmx noise lvls are 20 dbm 25 dbm for the 850w and the 1000w

but when i looked at the cybenetics for the 2021 version the dbm lvls are 30-35 fpr the 850w 1000w.

the same differenes are also when comparing the corsair rmx850/1000w 2018 version with seasonix gx or XPG CORE REACTOR 850W Gold [the last one i think is in the top ten recomended psu for 2021 on this site.] and the corsair still wins in the noise lvls there too.

they seasonix gx and the xpg core reactor and even be quiet straight power 11 are even cheaper with 20 euro then the corsair rmx here where i live but i am ok to pay a bit more for rmx if it is gonna work more silently then the first 3.

right now the prices here are SEASONIC FOCUS GX 850W FOCUS-GX-850 = 125 euro
CORSAIR RMX SERIES RM850X 2018 CP-9020180-EU = 148euro
CORSAIR RMX SERIES RM850X 2021 850W CP-9020200-EU = 138 euro
[ the newer version 2021 is cheaper then the older 2018 for the last 2 months. no idea why but maybe part of it is because it is noisier]

be quiet! Straight Power 11 850W Gold (BN284) = 160 euro
[ even though you told me in previous of my posts that the fan of the be quiet is superior then the corsair rmx and seasonic gx from the cybenetics stats the dbm noise levels of be quiet is like 5 dbm more then the corsair rmx. be quiet is more silent then seasonic gx psu but still corsair wins and it is cheaper too so its a win win to go for corsair rmx 2018 version here too.]

ADATA XPG CORE REACTOR 850W 75260042 = 117 euro but from its review here it is less silent then rmx.


SEASONIC FOCUS GX 1000W FOCUS-GX-1000 = 158 euro [ i cant find review where it has been shown the dbm noise lvls of seasonic gx 1000w but from what i heard across the forums it is 10 dbm more noisy then corsair rmx.

CORSAIR RMX SERIES RM1000X 2021 CP-9020201-EU = 180 euro
[but it is less silent then its previous version and it is close to the noise output of the seasonic gx 1000w]

i cant find from 3 weeks in the shops the old version of rmx 1000w corsair gold. there is only 2021 releases available.

option 1
do you think i should just go for the seasonic gx 1000w since if you comparing the noise lvls it is close to same with the corsair rmx 1000w 2021 verion. and it is also cheaper with 20 euro then the rmx 2021 one.
what are the advantages of the 2021 rmx1000w psu when comparing it with the seasonic gx 1000w when the noise levels of both of them are similar and about 30dbm each. and is it worth it to pay extra 20 euro for it . i also know that most of the guys on the site favours rmx instead of seasonic, but still ...

option 2
the other option for me is to buy 850w corsair rmx 2018 version and to pay the extra 20 euro more.
when comparing it with seasonic gx 850w gold. since from the reviews here rmx850w gold 2018 is about 15 dbm less noisy then seasonic gx850w. - here and also on the cybenetics lab statistics. this road i dont rlly consider right now part of the reason why is maybe i need you man to explain me in short why 850x psu is good choise instead to go for the 1000w psu [but only after you take into consideration that i am sensitive user when we talk about noise levels of the psu and also i am planning in future to upgrade gpu cpu and dont want in 3-4 years to buy new psu]

from my poor experience i think that when you get 1000w psu and you dont turn your computer for more then 20 hours plus playing 2 games at the same time plus streaming this will make most of the time the power supply to work on 60-70 persent of its load so this means the fan will be less loaded = less noise.

but if i buy now 850w then those 60-70 percent load of the 1000w psu here the load on the 850w psu will be 75-90 this means the fan will go to its max rpm to cool the system leading to high rpm making the max dbm noise output of the 850w power supply.

is this right. is my simple understanding logical. and which psu to buy. because god knows i want to choose one of those 2 options and start using my new rig at long last.

Sorry, not going to quote this wall of text on per point basis.
Yes, there's only up-to 850W versions of RM-x 2018. RM1000x CP-902009* is 2015 version (it came out in 2015).
Yes, on average, the noise output of RM-x 2021 is comparable to Seasonic Focus GX, but sub 70% load it's quieter, whether that worth 20 euro extra i'm not sure, because, honestly Focus GX isn't that noisy on low load either and in gaming, under like 30-50% load the noise output of your GPU and CPU coolers would likely be higher anyway.
You would only need a 1kW PSU (over 850W) if you're planning to upgrade to something comparable to today's i9 11900k + RTX3090, otherwise 850W will suffice, the noise output in gaming would be still pretty low even with RM-x 850W because it's not about average power draw but transient peaks, unless this is not only a gaming build but for like rendering or smth too.
Personally i'd go with Corsair RM850x 2021, but maybe there are other options like Fractal Design ION+ Platinum, Super Flower Leadex III ?

is this one https://www.pazaruvaj.com/zahranvawi-blokove-c3158/corsair/rmx-series-rm1000x-1000w-gold-cp-9020094-p308813795/

not 2018 version man cause it is different then
CORSAIR RMX SERIES RM1000X 2021 CP-9020201-EU which is 2021 and the one from the link is also different then yours RM1000x CP-902009* - which is 2015.

and since there isnt 2018 version of rmx1000w. is the 2015 version or the one from the link i give here better overall in noise levels then the 2021 version. 1000w.

i am not considering buying anything else honestly i am leaning towards buying corsair rmx psu just not sure is it worthed for me to wait more time until the old 1000 rmx version comes in stock which has better noise levels output then its newer version 2021 rmx1000w.
i dont know when you comparing both psu versions of the corsair rmx1000w working with my current pc build/[ and future upgrades] how much dbm on avarage will be the difference between both psu-s in favor of the old 1000w version. can u tell me some avarage number plz i know this is subjective but still it will give me a better idea. knowing this i will know is it worth it for me to wait more for the old rmx1000.

please tell me how much will be the avarage dbm output of the new corsair 1000rmx 2021 and the old corsair rmx 850 2018 version if they will work 24/7 on gaming rig while i stream at the same time playing 2 games plus openning 2-3 more different sites on my current pc build and lets say if in 2 years i go for rtx 6800 and one of the high end cpu-s. if the difference of the dbm output between these 2 is like 5 dbm lets say 2021 is 25 and the 2018 is 20 dbm then just for those extra 150w i think i can go buy the 1000w 2021. but if the difference is more like 10 dbm then not so sure. please man give me some avarage numbers or atleast tell me point me how to check this one.

you said that u personaly will go for the Corsair RM850x 2021. but the noise levels of it when compared to the 2018 version really push me back on this one and i will prefer to 2018 version of the corsair rmx850w in this case. for me the noise is deciding factor man.

i think from the noise test of seasonic gx it is overall worse then the rmx 2018 [850w] , and you also mentioned that sub 70 percent load the rmx 2021 version 1000w is quieter then the seasonic gx 1000w and i am also planning to upgrade in future to the high end gpu cpu on the market in the next years so 1000w i think is reasonable choice since after 2-3 years we dont no idea what kind of power hungry gpu and cpu will come out. even though 850w will be still fine for them i dont want to stress the psu so 1000w i think is better.

with great honour for your time and tips
dimitar.

I don't understand why you keep asking me this, here are Cybenetics reports, same data as in Aris's reviews :
Corsair RM850x 2018, Corsair RM850x 2021, Antec HCG850 Gold (Seasonic Focus Gold), NZXT C 850W (same), Corsair RM1000x 2015, Corsair RM1000x 2021.
Again, 2015\2018 RM-x is quieter than 2021, the latter is comparable in noise output to Seasonic Focus at higher load levels, at lower load levels it's still quieter. If you want silent PSU go for RM-x 2015/2018, 850 or 1kW is for you to decide.

i was searching for dbm noise levels on the cybenetics because i am leading to buy corsair rmx but not sure 850 or 1000 and 2018 or 2021 version and in my search i found that in this link
http://members.cybenetics.report:5050/d/cybenetics_j21_eu.pdf

the information about the EFFICIENCY AND NOISE REPORT is missing for both 115v and for 230v for rm1000x but the Avg Noise Output is 21.86 dB(A) for 230v is mentioned in the results there sadly i cant see the fan rpm results during the test because it is missing.

on this link http://members.cybenetics.report:5050/d/cybenetics_OxL_eu.pdf

for the 2021 version the Avg Noise Output 28.46 dB(A) for 230v so this is like 7-8 dbm more but on the review for the 2021 version it is said that the review specialist still prefer the 2021 version instead the older version because of the Corsair NR140ML (140mm, 12V, 0.27A, Magnetic Levitation Bearing Fan) which is more reliable in the long run then the 135mm Rifle Bearing Fan (NR135L) whichcools the old rmx1000w.
can please explain me what this means and how in general in the long run the 2021 fan is more reliable then the fan from the older version. because for sure from all the tests and all the reviews i saw the magnetic fan is making definatly more noise then the rifle bearing fan.

yes i know 29 dbm noise output for the 2021 is not big number and you cant call it noisy but still the older fan from the older 1000w rmx is doing 22 dbm on avarage and for me noise is deciding which to buy. atleast before i see your comment on this maybe i will see it worthy to suffer buying 7 dbm on avarage noisier psu if it is worth it in some other ways.

and yes for the few years ahead probably my rig will not need more then 600w when upgraded and now it needs from what i calculate on other sites about 460w so i am kinda comparing both psu-s on every segment when talking about noise lvls = the needed wats for my rig now and the noise both of the psu are doing on full load 1000w test aswell.

about the 850w rxm - 2018/2021 versions this are the 2 links from the cybenetics
http://members.cybenetics.report:5050/d/cybenetics_C3N_eu.pdf

and it is very helpfull for me when you look here at the
EFFICIENCY AND NOISE REPORT IN ACCORDANCE WITH CYBENETICS ETA AND CYBENETICS LAMBDA PROCEDURE for 230v for both psu-s where u see more agressive fan rpm speed for the 2021 version of the 850w leading to more dbm output then 2018 version on full load and around 450w load the 2021 is making 10.6 dbm where the 2018 version is doing 12.6 with close to 200 rpm faster fan speed.

do you think that after all this said the best choise for me is to buy 2021 rmx 1000w even if it is a bit noisier with 7-8 dbm more then 2015 1000w. sadly on cybenetics it is missing the 450w noise test/rpm in order for me to compare both 1000w psu on the point where they work with my current system wats requirements.

i remember you said that you will go for the 850w 2021 version but if u can spend the extra money will you get the 1000w 2021.

I don't understand why you keep asking me this, here are Cybenetics reports, same data as in Aris's reviews :
Corsair RM850x 2018, Corsair RM850x 2021, Antec HCG850 Gold (Seasonic Focus Gold), NZXT C 850W (same), Corsair RM1000x 2015, Corsair RM1000x 2021.
Again, 2015\2018 RM-x is quieter than 2021, the latter is comparable in noise output to Seasonic Focus at higher load levels, at lower load levels it's still quieter. If you want silent PSU go for RM-x 2015/2018, 850 or 1kW is for you to decide.
i wanted to buy the older 2015 version rmx1000w sadly it is out of stock everywhere in my country for the last 3 weeks. and waiting more doesnt mean it will come in stock in the next month ... months... so it will be either rmx 1000w 2021 or the older 2018 rmx850w
can u just explain me why the 2021 fan is better reliable in the long term then the older 2018/2015 fan when it is clearly doing more noise then the 2018 fan.
maybe something with the techonology of the magnetic fan when comparing with the rifle one

Don't look at avg noise output, look at charts.
well thanks for the help, i went forward and order corsair rmx1000w gold 2021 version. can you tell me since my rig will need about 500-600w at max. when the psu works on 500-600 w how much noise dbm output it will make 20 or 30 ty. because even though according to aris review of the 2021 version and that he said the magnetic fan is better then the rifle fan, i am still very sad that when comparing both versions of 1000w rmx corsair the old version is notably more silent then the new one.

i just hope that the newer factory made versions of 2021 corsair rmx 1000w are already tuned in such way that the fan is less agressive thus it is making less noise output then the 28-30 dbm during the review tests.
