Quietest PSU around

[Skulltrail]

Best one available is the Corsair AX range, I have an AX750 and the fan hardly even spins, only when I start stressing the computer.

With the AX series, the unit is passive until it reaches about 20% load, whitch would equate to about 150W.

What was the Coolermaster PSU? I had a Realpower 620W and it was very noisy.

I have a Silent Pro M 700 in one PC and a Silent Pro M 850 in another. Both extremely quiet.

Yeah my ax850 fan kicks in around 170w load. And even then its running on the lowest speed and only produces around 5db. The fan only ever kicks in when gaming. Prime95 and cpu stressing the psu fan stays off.

NZXT 750w Hale 90 - not heard it make a noise at all, gaming or otherwise. Which suits me just fine
