quiet power supply

[nootje860]

hi,

 

i recently bought a new cooler for my pc.

it cools very good and it is super quiet.

but there is one component of my computerthe power supply.

 

i need a minimum of 550 watt

and 1 6+2 pin connector.

and it needs to be quiet.

 

i would like to hear from you

Corsair's RM series of PSUs are particularly quiet, their fans don't even spin up unless it's under a certain amount of load. If you want absolute silence you could even go for a fanless one.

[Karumu]

any RM series power supply, since the have the Zero-RPM feature.

 

i can recommend my power supply aswell, because it's kind of the same.

Ur budget...??

[Resonancez]

Silverstone Strider series would be my recommendation other than the corsair series.

[Cubit481]

u can go with all the psu stated above and also if u want u can go with Seasonic X series...

If you can find a XFX XTR 550, they are better than the RM series.

Seasonic w/ Japanese Caps > Corsair

corsair rms have have cheap caps right?

[Scottonpc]

A PSU from the bequiet! range are good quality

Nope, internet mumbo jumbo.

[quan289]

What are you powering? What's your budget? Where are you able to buy from (links)?

 

Nope, internet mumbo jumbo.

 

It's not just "internet mumbo jumbo". The RM does indeed uses cheaper caps. Of course, the argument is that the RM is build and perform well enough to make these cheaper caps outlived its warranty.

Your right they are cheaper but it doesn't use "cheap" caps, just caps with a bad reputation and companies can change as can products with the same names.

 

As you said they outlive the warranty which is 5 years, which is a long life span.

There's a large discussion regarding the caps of the RM series of how "cheap" it really is, what sort of application it should be used in, as well as how these caps don't often meet the specification that it is rated for on the datasheet (which other quality caps will not only meet but exceed it).  I've personally have dealt with blown caps from CapXon and Ltec in PSU before that I had to recapped within a three year period in a well-ventilated PSU. Some of which are in the same series used in the RM.

 

At the very least, they are certainly better than some of the trash Sacon, which I've seen failed within a year. Plus, recently, Senko Denko made a high-purity aluminum plant in China, so the argument regarding why these caps may prematurely fail due to impure aluminum may not be true anymore.

 

Regardless, the RM series isn't bad. It certainly recommendable if the price is right. If it turns out that these caps do failed, there's a 5 year warranty as you had stated.

sorry for my late response may budget is arround 50€ and thanks for your great response

The only 2 "cheap" caps, are the two at the end of the circuit and they're only there to filter out the last like 5% of power, while the other caps (non cheap ones) have already done the work.

 

Tiny Tom Logan did a video about it and complained the entire time about people bitching about the Chinese caps, and mentioned awhile back (like 5+ years ago) that they had issues, and have sense been fixed.

 

They wouldn't give it a 5 year warranty if it couldn't handle being used for OVER 5 years. 

 

 

 

@Op if you want truly silent, get an EVGA 750 G2, it has a switch on the power supply that makes it passive until 45 C internal PSU temperature, it doesn't matter how much of a load you put on it, the fan WILL NOT turn on until 45 C

TTL of OC3D had left a bad taste in my mouth with the few reviews I had read/watch, in which I don't watch/read them anymore. Regarding PSUs,  they didn't crosscheck their data before publishing it when they overloaded the minor rails, read the o-scope readings wrong, and posting a review when it seem like their testing equipment is not operating correctly. If we were to reference people, Tator Tot, retired Product Manager of OCN and a regular at Jonnyguru, also don't have much faith in their reviews.

 

The RM series are a single Japanese cap in the primary side of the PSU (the secondary caps usually failed before the primary cap). At the furthest stage, the RM450-650 uses polymers on the modular board, as well as for the DC-DC convertors. The caps that most of the ripple/noise from the primary stage are filtered by CapXon and Teapo for the +12v rail. On the 750-850 model, uses Ltec for the late stage of the modular board, two Taicon or Nichicon for the DC-DC convertor, and full Ltec for the +12v rails.

 

TTL was likely referencing to the whole bad cap scam back in 2001/2002, where Luminous Town Electronics had acquired the stolen Rubycon P50 formula. That's over 10 years ago, and that formula aren't used anymore. The thing is that people, including myself, are still dealing with failed, blown LTEC and CapXon caps even in a well-ventilated PSU. Well, at the very least, the quality of these caps should go up, as I have stated, there's a new factory for high-purity aluminum in China now, so there should be no excuses regarding impurities seeping into the electrolytes and causing hydrogen build up.

 

Nonetheless, we just have to wait and see in 5 years how well the unit will last being mass-produced in a semi-passive environment. The RM series isn't bad for a mainstream unit, and depending on the price, I'm still willing to recommend it.

 

@Op if you want truly silent, get an EVGA 750 G2, it has a switch on the power supply that makes it passive until 45 C internal PSU temperature, it doesn't matter how much of a load you put on it, the fan WILL NOT turn on until 45 C

 

The EVGA Supernova 750w G2 is indeed an excellent PSU, but it is out of his budget range.

[spwath]

Evga 750g2 nvm out of budget but you should invest in a quality psu

[quan289]

sorry for my late response may budget is arround 50€ and thanks for your great response

 

Can you provide us a link as to where you are able to buy from, so we can know what is available to you at a particular price range?

What is the specification of your computer, btw?

 

The BeQuiet Pure Power L8 CM 580w may be an option in that price range. http://geizhals.eu/be-quiet-pure-power-l8-cm-530w-atx-2-31-l8-cm-530w-bn181-a674412.html

There's a few other units I would like to recommend, but it is in the ~75€ and is over your budget.

I think until we actually see people in 5 years with RM series then we can decide

 

I mean, if they gave them 5 year warranties I'd expect they're planning they'll be functional in ~6-7 otherwise they'd lose a FKton of money lol

[quan289]

Well, if we were to based it off of solely the warranty period, the early revision of the CX series had reported primary cap failures, in which cause it to be updated in the current third revision. So in practiced, it failed before their calculated lifespan. But yes, generally, the warranty from a reputable brand can reflect how long it is expected to last in accordance to it specification.

 

Either way, there are other variables that can promote cap failures as well as the rate the cap loses it filtering abilities, so the condition that these caps are operating in the RM may differ from my own experience. Like we both had said, this is something we need to wait 5 year to fully judge.

[ObeseWalrus]

XFX, Seasonic, Corsair, Antec. All reputable brands and they should have something in your pricerange. Just remember to buy a quality PSU, or else you could destroy your computer and burn your house down.
