I have a x thermaltake silent 480 watt right now, and its starting to make high pitch sounds and is very loud. I've had it for about 3 years now i think its time for a new one. I need one thats very quiet because this one i have now is too loud. Also want those new psu with the plugs on the psu idk what they are called. a 120mm fan and 500 watt, anyone have one they would recommend?
