Not just the power supply, but also the mains power going into the supply. Since personal computers have become commodity items, the low cost power supplies in them typically aren't designed with enough chutzpah to deal with dirty input power, or to clean it up sufficiently to satisfy the (sensitive) digital chickens it's keeping fed. This is one of the benefits of (some) UPS systems: they clean up the mains power before the power supply in the computer has to deal with it. -- Thanks, DougF (KG4LMZ) -- PDML Pentax-Discuss Mail List [email protected] http://pdml.net/mailman/listinfo/pdml_pdml.net
