Is an AVR still necessary if the desktop PC is already connected to a UPS?
Many articles online including this link to Wikipedia:

State that the UPS already has built in circuitry that is capable of protecting computers from power fluctuations and even the instruction manual of my UPS states that it is capable of protecting computers and other connected loads from power fluctuations. Since the UPS basically does the same thing as the AVR but with the added function of providing backup power from a battery, is it still necessary to have an AVR connected to the desktop PC if the PC is already connected to a UPS?
