Would you recommend a quiet (important) and yet cheap power supply which I can use also for overclocking ?

My motherboard is an ASUS P5Q with Core 2 Quad Q8200 which I want to overclock from 2.33Ghz to 3.0-3.2Ghz. I use at least two hard disks, DVD and a bunch of Firewire and USB externals... My old PS has gone defected, and I believe it was due to the overclocking I used for the past 6 months.

Thanks !
