Does anyone know if off-board toroidal power supplies are available for PC's? I just sat through a lecture on power electronics and spent most of the time thinking about if it would be possible to modify a hifi power supply, such as those made by Naim and Cyrus, to supply power for a PC. The benefits would be that it is silnet and probably cleaner than a standard switch-mode jobbie in a PC. Wouldn't be cheap but may be worth doing on a one off project. Cheers for any stuff.
