I have bought this chassis with a power supply integrated, and it makes a lot of noise for me (as much as the old big desktop chassis). The noise comes from the power supply and its an uninterrupted "breathing/blowing" noise. Here you have some specs of the power supply.

1. Do the power supplies make noise?
2. How to know if a power supply will make noise?
3. I'm looking for a power supply that doesn't make noise, do you know one for mini-itx?
4. Laptops dont make too much noise, what should i do to get a mini-itx as silent as a laptop?

I have a EVGA Z77 Stinger, an Intel 3570k and 16 Gb of memory.
