Corsair with Gold Rating and above are extremely quiet, especially at idle.
Power range from 650 - 1200W, they are expensive but IMO are worth it and will last.
Also Corsair customer service is very very good. The fan was starting to make a small rattling sound in my HX1000 so i emailed corsair for a fan replacement however because doing it myself would void the warranty they offered to replace the entire unit. I couldn't be bothered to send to power supply to i just bought a 140 apache and i am controlling via 4pin PWM via motherboard so mine it virtually inaudible (i don't recommend this if you don't know what your doing) however its nice know the offer was there.
