PSU noise?

[SauronsV]

Is the PSU normally audible?  I dont hear it over the fans or anything I just want to make sure nothing is going to break. On my phone it says the db is 25, is that bad as well?

 

Sorry im a noob.

If it works, it doesn't matter.

Phone's really aren't a good way to measure sound. But yeah, the fan making noise is normal.

Don't trust what you phone says about noise levels, it's not that accurate. PSU's will make a fair amount of noise under load. What type of noise is it making? A high pitch noise (known as coil whine) is completely normal, as this is just a magnet inducing electricity (to put it simply). Loud fans are also normal under load, however you might want to inspect the unit to see if something like dust is blocking the fan.

What psu is it and is it free from dust. Phones are that accurate at measuring sound levels.

perfectly normal. They don't use the best fan in that psu.

it seems to be like a normal fan sound except from a psu, doesnt sound bad, im just surprised a psu makes this much noise, for example, when i disabled all my other fans, i could hear the PSU, is that normal?
