Very quiet, good quality PSU

[nox_]

Hello all, I'm looking for a 500 to 600 watts psu that would be silent as possible, as it comes to psu's I'm not particularly well versed, looking for advice/opinions on what should I get. So far, I'm consider this one : https://www.amazon.co.uk/Be-Quiet-Straight-Power-supply/dp/B078X22YHM

even if an older model I currently use the Cooler Master V550 in several systems... it is with a fan, but you won't ever hear it. Well I don't not in a cheap case, neither in a fractal design Define XL2 

 

If money isn't a problem you could also go for a seasonic platinum fanless PSU... but this is a totally different pricerange

The straight power 11 is solid. If you are looking for cheaper optioms, look at the Corsair TXm

Will look into Cooler Master, I could go for fanless, but not really sure about that, not very sold on fanless PSU's somehow,  might be biased or whatever, but gonna look into that also.

Not really that much cheaper in my area, but thanks, if I find it for a good price, might go for it.

The fanless Seasonics are tested in a 40° C hot room for a stresstest and a long period of time. 

 

Just as a note about the Fanless ones... How reliable... well 12 years warranty, that says a little

My Corsair VS was rattly as heck, but when I switched to bequiet base model Pure Power 9 it's actually pretty solid. Have not tested it in an isolated environment, but it's pretty much inaudible when you creak a window. Now I'm on Straight Power 11 and it's damn quiet. Would go with the fanless Seasonic though, they are absolutely reliable, have built in protection, and of course inaudible.

Straight Power 11 would be a good choice. Very good quality Silent Wings 3 fan in it, you shouldn't hear it.

What system are you powering? Depending on the load, some PSUs may be quieter. Fanless PSUs expect some passive airflow through the case, so if your case e.g. doesn't have fans of has a PSU shroud, I would recommend avoiding them.

Fairly sure they wanted a very quiet PSU. The TXM is definitely not "very quiet".

TXm isn't loud either. Not louder than a CPU fan or GPU fan at any rate.

OP didn't ask for a PSU that isn't loud. They asked for a very quiet PSU. Looking at the testing results from Cybenetics, the fan RPM goes from 1360RPM at 20W load to 1840RPM at 550W load. Compare this to the Straight Power 11's 240RPM at 20W load to 1300RPM at 550W load.

As for comparing it to the CPU and GPU fans, that's ridiculous. We don't know their setup. e.g. my desktop is fairly quiet, with the CPU fans running at ~500RPM and the GPU fans at 670RPM at full load. Running a 1300RPM fan would most definitely be noticeable and annoying.

Still deciding, so far thinking about 5 3600 and 2060 Super or  RX 5700 nothing crazy, case should have decent air flow, but I'm also looking into making my setup passive, not sure if that's possible, might have to settle for as quiet as possible.

Both of those are 175-185W ish GPUs, so the system should pull about 250W during a gaming load. 

The Straight Power 11 550W seems to be the quietest among the similarly priced PSUs that don't rely on a semi passive mode. 135mm fan at approx 350-490RPM (realistically a bit lower, due to lower ambient temperatures). I couldn't find reviews of the 450W, but it should be about as quiet at the same loads. 

Some cheaper options would be the Formula 450/550W (both 120mm 540RPM, non modular), or the Whisper M 450W (135mm 470RPM, fully modular). The fan RPM for those will not be any lower, as that is their minimum RPM (the SW3 is capable of spinning amazingly slowly). 

The Whisper M 650W is technically an option, but it's not very quiet above ~500W. At low loads, it's as quiet as the 450W.

With the Whisper M, it uses the Corsair Type 4 pinout, meaning you can use any custom cables made for e.g. the Corsair RMx. It can be harder to find custom cables for the Straight Power 11. 

Numbers from Cybenetics, you can verify for yourself. I used the numbers from the load table, but you can also find noise graphs at under 32°C ambient (though I do not particularly like these).

Thank you for such detailed response,  I will look at custom cables for Straight Power 11, if none will be available, might go for Whisper M 650W, it should be fine with my setup, don't think I will be getting something more powerful that would require ~ 500W.
