ACP power output question

[Moteel]

Greetings,
I've recently moved to a house with rather bad wiring, and the power level tends to fluctuate at times when the usage is high, I want to buy an UPS in order to not risk damaging my computer, but I'm not really sure what max output I need, considering that I don't need to be able to run solely on batteries, but only need to compensate the occasional voltage loss (which can take up to an hour or more at times).
It's not a -big- losage, other electronics (TVs and such) handle it quite normally, but the computer has some fairly high-end components and has a quite high power usage (500W source, mostly used too).
Thanks.

What you need is a Line Conditioner, not a UPS. APC makes some that we use - it's an automatic voltage regulating transformer - it automatically adjusts the taps on a transformer to keep the voltage to the PC inside normal limits despite wide swings in supply voltage.
The unit under my desk right now is an APC Line-R 1250.
