Quiet PSU recommendations please

[CroSsFiRe2009]

As others have said, you need to identify the source of noise first. Unplug any fans that you have in your case and any unnecessary hard drives. Slowly add your parts back until you're sure of where the noise is coming from.
If the power supply is truly the source of the most noise, upgrading is a solution but if you don't mind voiding your warranty, swapping the fan inside it for a quieter one is always a cheaper solution. You just need to remember to get one with sufficient airflow that runs at almost the same rpm as the stock fan since you need to make sure the fan is still working at low loads since less voltage is supplied to the fan.
If it's your hard drives, elastic suspension or rubber mounts will help decrease noise a lot

I will attempt a silencing session this weekend.

I did not experiment but I believe that most of the noise is my PSU as it was the only major internal change after upgrading to a Fractal R3 case from an Antec 900, the Fractal should be quieter. I am now stuck between a Seasonic X-650 which I might be able to get a APM on from NCIX as Newegg have it for $159 or should I just go with the Seasonic M12D 850W which is on sale at NCIX for $149, I do not really need 850w though.

150 is not a great deal for it, be a bit more pacient if you can.

The cheapest x-650 atm, it gets lower, but the usual retailers don't have it stocked atm.

I wouldn't buy the M12D as it's features are a slightly less (although insignificant) and it goes on sale for $100 quite often, way less than the current sale. It's an amazing value at ~$100, but right now I wouldn't even consider it over a similarly priced Seasonic X-series, especially if you don't plan on dual high power graphics.

NCIX approved the PM on the Seasonic X-650

I went to NCIX today and picked up the Seasonic M12II 620w PSU and will atempt fitting it tomorrow night, total cost was $89.99, hopefully it will be alot quieter than the OCZ Modstream 750w in there now.
