Corsair Refreshes RMx Series PSUs with Magnetic Levitation Fans, Upgraded Warranty
Corsair on Wednesday refreshed its RMx series premium power-supply series with new 2021 models. Available in capacities of 1000 W, 850 W, 750 W, 650 W, and 550 W, these PSUs succeed the previous generation RMx series by featuring a new 135 mm "Magnetic Levitation" bearing fan that's designed for extremely high durability. This design change, along with other minor updates to the internals, allow Corsair to give these PSUs 10-year warranties. The PSUs continue to offer Cybenetics Gold switching efficiency with Acoustic A- rating, full modular cabling, and include two 4+4 pin EPS connectors on all models except 550 W. Prices should be on-par with the outgoing RMx series.

Its one of the fans that I will strongly recommend not to buy because despite the gimmicky "magnetic lev" it is very loud at high RPM. The 2x 120mm and 1x 140mm ML fan all behave about the same. The 140mm one is slightly quieter due to the slower RPM.
;)
Having owned their previous models i'd return that thinking it was faulty!
I own some ML120 and ML140 fans and they're super quiet at low RPM so this is a bit of a shock to me that they're so bad in the PSU
edit: ah there was two models with different RPM, the high RPM one was a leafblower
Well technically corsair having bought a company that was in some patent lawsuit against steam over the buttons on the back of the controller...
I remember deciding corsair is a terrible company and I never want to buy any of their products again...something along those lines anyway.
Now, to the article, didn't both 2015 and 2018 RM-x (and RM 2019 too) already have 10 years warranty ? What are you taking about @btarunr ?
Is this for real? Thats insane if unit was not faulty.
quality fan – low noise with high airflow
The dumbest thing this problem could be avoided if CWT / Corsair added a simple on/off switch for the hybrid fan mode so users had the option to have it off or on rather than it being forced on them
At least according to crmaris it seems to have to do with putting some load on the minor rails which seems to make the fan controller go nuts. Could just be a poorly programmed firmware. Wouldn't be the first time a company has done that, or left something at default.How would that help when the issue is related to the fan controller kicking the fan into overdrive because there's an above a certain level of pre-defined load on the minor rails?
You just want to turn off the fan controller altogether?
Here's the thing. The MagLev bearing isn't the most quiet. It's more in line with DBB noise wise. But because the impeller literally touches nothing, they almost NEVER DIE. They are hard to beat for my application of "system in a remote data closet with blowers."
Mag levs never needed to be in this PSU, the original Hong Hua blue Jay fan was already great, but maybe as some might have said, Corsair ended up with tons of unsold Mag levs so they repurposed them with this PSU, i don't know
If you are too busy to provide one, that's fine I get it. I was just hoping you had it at hand or something.
The 650w version starts at 129$ which was the MSRP for the 850w 2018 RMxYeah, but why replace an already quiet fan with a loud mag lev one, sure it sounds cool in marketing but the reason why nobody talk about corsair mag lev is because the hype for them died as soon as the review cycle came revealing they are as loud as Noctua's industrial fans, seriously go look up you tube videos about how loud it can get, i have never seen anybody recommend Corsair Mag lev fans ever since
