Quiet Power Supplies

lightsource

I'm buying a new power supply, I currently have a OCZ PowerStream 520W and I want to upgrade to a higher (or close to the same) wattage power supply.

I'm trying to perfect my PC to be very quiet and I've got most of the things I need sound proofed, now I just need internal/external case mods(rubber case feet, fan silencers, rubber screws, dynamat, etc.).

These are the power supplies I have lined up and I want to know if any of you have personal experience with them and which ones are quieter. What would be PERFECT is if anyone who has owned or does own a PowerStream would tell me a power supply you have upgraded to and has been quieter.

OCZ GameXStream 700W
PC Power & Cooling Silencer 610W (Maybe 750W*)
SeaSonic S12 600W
SeaSonic M12 600W

Which one is quieter?

Go for one of the seasonic or OCZ.The PC Power and Cooling uses a 80 mm fan.I think the others uses a 120mm fan.
Any model with 120mm fan is quieter than a model with a 80mm fan.

I have that Seasonic S12 600W and it has 120mm fan and I newer hear it!

And hackerx I realize the larger the fan the quieter the fan however in some cases (depending on how much CFM a fan pushes and how much a fan NEEDS to push) the 80mm could have been more quiet than the 120mm. The only reason I'm even questioning you is because I looked at PC Power & Cooling's website and they showed a diagram that made total sense to me that's in a PDF of theirs.

EDIT: I just looked at pc power & cooling's website, they've got a 26dba-35dba rating, which is too high for me.

Thanks

Cool. Thanks A Lot

I was also wondering which of the Seasonics are quieter, I realize that the M12 version has two fans but I don't know why they would add a fan if the S12's fan was sufficient.

Any Ideas?

Enermax Liberty running in a Antec P180 and I can't hear the thing on... they're real quiet. Same with the Enermax NoiseTakers.
