Hi, I currently have a PC P&C Silencer 610 and despite its name I've determined it's by far the loudest component in my system. I'd like to replace it with the quietest PSU I can obtain for still reasonable money. Current parts: i5-2500K, 16 GB memory, Crucial m4 and 500 GB HDD Intending to buy either GTX 660 Ti, GTX 670, or HD 7950. As you can see I don't have a ton of components. I want to go as low as is reasonable on wattage while still making sure the PSU isn't too stressed to keep it quiet. Maybe 500W? If it can run without the fan spinning at all at idle that'd be even better. Max price is ~$140 but would prefer to stay < $100. Thanks for any recommendations.
