[SOLVED] Quiet PC Project: Silent PSU

[buri]

hi everyone, i am trying to make my pc more quiet so i focus on 3 elements to change to reduce noise.

 

1- psu

2- rear fan

3- cpu fan (already ordered noctua l9i)

 

my components;

 

- i3-8100 stock

- gigabyte lga 1151 z370 hd3

- gigabyte gtx 1060 3 gb

- samsung evo 960 m2 nvme 

- corsair vengeance lpx 8 gb ddr4

- corsair carbide 100r case

- corsair vs550 psu

 

- 2x 4tb wd red nas hdd - thinking to add soon

 

for my setup what is the most quiet psu on the market i can buy? and i think my wattage comes out around 365. PC will run 24/7 as i am thinking to turn it as a media server.

 

thanks alot

Think silverstone and seasonic Both make fanless units

The quietest you can get is going to be a fanless model, but those are quite expensive, usually upwards of 75% or more expensive compared to their brothers. Next would be to buy a hybrid model which shuts the fan off until the PSU reaches a certain temp. Most good quality units have this feature. I personally have this one in my home media PC that I only use to watch Hulu, Netflix or Amazon prime.

you think fanless psu is a good idea? i seen some posts and videos that any psu needs fan cooling to be efficient

get a semi-passive psu fan. like the corsair rm650x, or whatever wattage you want. the psu is really silent. fan is not spinning at lower than half the wattage and even if on it's super silent

i heard rm650x and rm750x are very quiet. Also be quiet brand has quiet ones. 

 

i was just thinking to change the fan of my PSU to a good one, can be an option?

no, it is not because you need the fan anyway.

Get a good, quiet PSU.

You don't need to spend that much either.

If you want to be cheap:
be quiet Pure Power 10 or Bitfenix Formula

Otherwise Bitfenix Whisper M

 

You have to get the 450 or 550W bitfenix because 650W and up have +50% more fan RPM under lower loads.

Fanless does not mean quiet.

For that rig, 650 or 750W is total overkill - you could power at least 3 PCs with that - waste of money with no benefit for you.

And no, lower relative load does NOT mean quieter!

Especially if they change the fan for higher power models.

 

 

Be quiet is a good idea.

in cooler master psu calculater load wattage came out 316W and recommended was 366W so a 400W be quiet Pure Power 10 should be sufficient, right?

Don't use those "PSU calculators". They overestimate by a ton. Take their estimate, halve it, and you're closer to the real power consumption.

Yes, it's plenty.

You can perfectly get a dead silent PSU without semi-passive mode.

 

Regarding EVGA B3, it's highly possible that when the fan turns on it does so with high RPM (Cybenetics: https://www.cybenetics.com/code/pdf.php?id=yfR), and you don't want to be hearing the fan start and stop every X minutes/hours. The B3 is not a safe bet, and Pure Power 10 & Formula (like Stefan recommended) are absolutely great units in terms of noise.

Get a Powermeter.

Those PSU Calculators are totally off if you use it wrong. Wich means input more than GPU and CPU.

 

But yeah, a 400W Pure Power 10 is plenty!

I used a 400W Pure Power 10 with my i7-3930K and RX480 OC and still had plenty of room.

The aforementioned be Quiet units are probably going to be fine for your needs. If you can't find them for a reasonable price, then something like a Corsair RMx/RMi should do nicely as well.

thanks everyone, i think i will order the pure power 10 400W and check how its. 

 

here is the current psu´s noise, i dont know if its normal or needs to be checked. its under warranty still

at the end i went with Straight Power 10 400W w/ silent wings 3 inside. DEAD SILENT  recommend it to everyone

 

Only drawback i see, not modular and still coming with FDD connections, wtf
