 | Hey,
I've recently moved to a place where the power appears to be
dirty; the lights in my house sometimes momentarily dim and brighten.
The effect on the lights is tolerable, but I'm wondering how this
change in power will affect my computer system. I'm running a big
machine (dual processors, 3CDRs, lots of PCI and USB devices) so I have
a 650watt power supply in it. Now, I don't really need a UPS to supply
me momentary power in a blackout so much as I need one to clean the
power. Will one of these cheap UPS's sold for under $100 (some as low
as $30) do the trick? I'm a computer geek, but know relatively little
about volts, amps, vA, watts, and other power concerns. Please, some
advice. Thanks,
John

Those cheap ones will only kick in when the power drops significantly
(like <85 volts), and provide some filtering. Power cleaning requires a
full time power converter, like one made by APC for servers (not cheap).
