Quiet and durable PSU?

[RainingTacco]

Hello. Im looking for a quiet and durable PSU on the market, that will last me at least 10 years[both psu AND fan]. Im looking for 650w 80 Gold plus certificate, fully modular. Ive read numerous reviews, but cant make up my mind.These are few picks ive chosen:

Importance of factors:

1. Durability

2. Quietness

3. Performance

Bitfenix Whisper M 650w

Pros: Excellent performance, multi rail, cheap

Cons: Fan is of mediocre quality,not quite quiet while close to 80%-100% load[can anyone confirm this?], 7 year warranty-have absolutely no idea how it is covered in europe[Poland]

Corsair RMx 650W

Pros: Excellent performance, very quiet in whole load range, 10 year warranty

Cons: Single rail, expensive[10-15 dollars more]

Corsair RM 650W

Pros: Good performance, quiet, but not as quiet as RMx, 10 year warranty, cheap

Cons: Worse fan[?], worse capacitors, single rail

Enermax Revoluton D.F 650W

Pros: Good performance, very quiet[with slightly worse quietness in specific scenarios], multi rail, relatively cheap

Cons: 5 year warranty

Seasonic Focus GX Gold 650W

Pros: Good performance, 10 year warranty, good fan quality[can anyone confirm this?], relatively cheap

Cons: Single rail, not so quiet[can anyone confirm this?]

Riotoro Enigma G2 650W

Pros: Cheap, Good performance,10 year warranty

Cons: Single rail, mediocre fan[confirm?], 85*C caps, warranty-have absolutely no idea how it is covered in europe[Poland],not so quiet[confirm?]

Super Flower Leadex III 650W

Pros: Relatively cheap, Excellent performance, very silent

Cons: 7 year warranty, have absolutely no idea how it is covered in europe[Poland], single rail

BeQuiet Straight Power 11 650W

Pros: Multi rail, Excellent/good performance, very quiet[confirm?], good quality fan[confirm?]

Cons: 5 year warranty, expensive[10-15 dollars more]

 

Basically i would like to know how important is the single rail vs multi rail while both PSU have OCP. If someone could shed a light how warranties are resolved for Super Flower, Bitfenix and Riotoro products in europe then i would be very glad[and then their products would be more attractive for me].I would also want to know if Bitfenix Whisper, Enermax Revolution,Be Quiet Straight Power, Riotoro Enigma and Seasonic Focus GX are quiet[less than 30 at max]? Tomshardware reviewed 550W version of Whisper, and 650W might be louder. I dont have any reviews from Tomshardware or techpowerup[most reliable about noise levels] of Seasonic Focus Gold[same platform as GX] or Seasonic Focus GX. TH reviewed 1000W Straight Power and again 650W might be quieter.Same for Riotoro Enigma[850w vs 650W, also dont know if they fixed the overcurrernt problems].  No reviews of Enermax Revolution from TH or TPU

I find most quality PSUs almost perfectly silent, especially BeQuiet

How is it the RM has the "worse fan" when it's the same fan as the Seasonic Focus? 

 

And why is single +12V rail such a negative?  Do you plan on shorting something out? 

[RainingTacco]

Well Seasonic isnt the quietest PSU under full load as cybenetics report shows, but Corsair RM implementation must be better if it doesnt cause such noise output[less heat? less aggressive curve that doesnt try to excesivelly cool down the PSU, well that at least increase longevity of psu, but not the fan?] 

Idk i always thought that it doesnt really matter single vs multi rail, but recently ive read that its safer. Since single rail PSU can also have OCP on each rail i dont really know how this argument hold?

Multiple +12V rail is safer... For 1% of the 1% of potential failures/faults. 

 

Corsair's fan curve is better because they use a programmed MCU for control.  Seasonic and others use a simple thermistor and analog IC configuration.

Thanks.So you say that Corsair actually have more expensive solution? Well that's good to know that the price difference is justified

Seems the fan is indeed slightly different[as per cybenetics]

Seasonic: HA1225H12F-Z

RM: HA1425M12F-Z

At first glance it appears that they are the same but different in size, but one is H12F-Z and the other is M12F-Z.Seasonic is fluid dynamic bearing, and the other is rifle dynamic bearing.

Diameter is different, but bearing is the same.  Seasonic doesn't use an FDB.  That's why they call it an HDB.  It's also a rifle bearing.

Seems like you've already done a lot of research. What system are you powering?

For the units you can't find reviews on for noise testing, try Cybenetics. They have a pretty good catalogue and should have some of the units you're looking for. They have the Whisper 650W on there. https://www.cybenetics.com/index.php?option=power-supplies

Thanks, ive already checked cybenetics and some PSUs like riotoro, whisper and seasonic confirmed my suspicion that they arent that quiet. Shame they dont have Enermax Revolution DF tested, as its highly in the TIER list on this forum. So im left with Enermax Revolution DF, Corsair RMx or RM, Be quiet Straight Power or Super Flower Leadex III.

Considering that Enermax Revolution DF have 139mm fan, that spins at 850rpm full load, it can't be that loud right? Im 99% sure i will go with corsair RMx[2018 revision] since it has outstanding performance, it is quiet, has great warranty.  

 

I will power a measly Ryzen 2600 and 2060 Super or 2070XT. Yes i know its an overkill but i want a headroom for some upgrades. Im also considering going full ham and buy 850W, because in the future[as i get more cash :(] i might buy something along 9700k and 2080 Ti. After all difference between 650W and 850W is like a joke its 25 dollars.
