So as the title says: Which caps to use in ATX Power Supplies?

We are a ATX Power Supply manufacturer about to launch a new series of silent hi-end Power Supplies, so we are looking on inputs on which brand and model capacitors to use in order to get the perfect mix between quality/performance and price.

So, from spending time on this forum the obvious choice would of course always be to use japanese hi-end capacitor brands - However surprisingly enough most consumers does not even know what a capacitor is and most probably will not pay extra to get japanese caps....
