Don rearranged some electrons to say:

I just got my PC back from the repair shop. The power supply
went and the technician said that it was probably because the
machine was subjected to many periods of low voltage. He
suggested I get a UPS with automatic voltage regulation. I'm
looking for something in the $80 - $100 range. I'm more
interested in the AVR function than running my machine in a
blackout and power outages aren't as much of an issue. Can
anyone recommend something? I saw that Best Buy has their
GeekSquad G875U on sale and I was wondering if it was worth
getting. Or should I look at other brands, i.e. CyberPower,
Belkin, or APC. Any thoughts?

PS: Do NOT use a voltage regulator (ferroresonant transformer) in
combination with any type of active power factor correction,
either in a UPS front end,

Are you seriously suggesting that the original poster is supposed to
know whether the regulator is on the front or the back end of a UPS?
Should that be specified in Tripp Lite's UPS/AVR documentation,
David?

or a power supply; they will not play nice together. Have seen
the damage that can be done on a poorly designed 15 kVA UPS with a
ferroresonant transformer in front of it (it caught on fire).

Huh? Are you suggesting that UPS/AVR combinations are a poor design?
You must be making millions on your own dazzling designs, David,
considering the fact that Tripp Lite makes many different UPS/AVR
combinations (and does very well selling them).

Please provide more clues about what you are trying to say, David.
