The only companies i would choose from are FSP, Seasonic, OCZ & Silverstone Zeus series or this one , PCP&C and Zippy. In that order. FSP good for budget. Seasonic is good for quietness. OCZ is just lots of power on a single 12V rail and PCP&C for efficiency. Zippy for all of the above and just awesome build quality. BTW for the PCP&C 120mm fan psu's they are made by Seasonic.
