Re: Studio XPS 9100 UPS

SOME of the "Active PFC" power supplies do require "true sine wave" UPS systems, some require UPS systems that have a less than 4 ms switching time and finally some will work with almost any UPS.  And this is throughout the industry, not just Dell.  Even new standard ATX power supplies fall into this as almost all new power supplies are the Active PFC type (which are greener).
