For PC users who are serious about noise there really is no alternative to a passive power supply. Sure there are power supplies on the market that operate incredibly quietly (such as Be Quiet’s Dark Power Pro range) and even power supplies that don’t spin up their fans until they pass a certain load amount, normally 40% load (Corsair’s AXi range for example). However, a fan is still a fan whichever way you butter it up and a fan means some noise irrelevant of how quiet that fan is.
