New PSU - efficient, quiet, fully modular

[Senzelian]

Hey everyone,

 

I'm looking for a new power supply that is
 

• quiet.
  Basically I want it to be inaudible. The quieter the better.
• efficient.
  I think 80+ Gold would be a good choice.
• fully modular.
• under 150€.

 

(ATX sized of course)

The PSU guide here is pretty good.

What are your system specs?

The PSU tier list? It doesn't take noise in to consideration so isn't really going to help them find what they are asking for.

Currently a Ryzen 2700, 2x 16GB RAM, GTX 1080, 3 SSDs.

I'm expecting to upgrade the system this year if AMD and/or NVidia come out with new hardware.

 

Edit: The Straight Power 11 looks quite compelling, but I have had bad experiences with be Quiet's 120mm Silent Wings 3 fans at higher RPMs. No idea how good their 135mm ones are.

Checking your profile, you currently have the ax760i? Are you still using that PSU in the system? If so, why are you replacing it? 

 

The straight power 11 should be reasonably priced if you're buying in Germany. It uses one of be quiets silent wings fans which will always spin but at a low rpm, virtually inaudible.

The Corsair models I listed have semi passive fans (stop/start depending on load & temperature).

I still have the AX760i, which still works, but the fan makes quite a loud bearing noise. It has a proprietary connector, so I sadly can't replace it. It ramps constantly up and down and is even louder than my GPU at times.

That is also why I don't really want to buy another Corsair PSU. I'd rather try something else.

Changing the fan won't fix that.  That's the fan controller.  Plugging another fan into the same fan controller doesn't make the fan controller act differently.

 

Also, the RMx, RMi, HX and HXi are all newer than the AXi and have better fan controllers that prevent the ramping up and down of the fan.

But why did I not notice this issue for multiple years until just recently?

Changes in your build?  *shrug*

 

You listed your core component changes, but what has changed since you noticed the difference in fan speed?  CPU, GPU and RAM are not the only components in a PSU that use power.

 

The older Corsair PSUs took +3.3V and +5V too much into consideration for fan control.  So even adding things like RGB or USB devices would trigger the fan to spin faster.

 

Recently, I have found that if someone outfits a PC with all of the available Corsar RGB kit (which runs off of +5V), a user can actually overload the +5V DC to DC.  Not kidding.  Hind sight is 20/20, but I wish they ran the RGB LEDs off of +12V, but that would require implementation of a DC to DC on the RGB devices (and LED drivers tend to DC to DC off of +5V if you don't bother to do any additional engineering).

 

You might find the data at http://www.cybenetics.com useful as they test several combinations of loads, including high +3.3V and +5V and not just high +12V.
