Got an *ancient* (and I do mean ancient) APC UPS... all it does is back
up my wireless router. Battery is done. new one I expect to cost
$30-40 (which I find extortionate as I buy them for work at about $10
all day but still.)
1) buy a new battery. Be happy for another 5 years or so. Cost $40 max.
2) buy a new true-online UPS for my PC, and rotate the old, sorta-decent
one currently serving PC to wireless router duty. Would cost $266 for a
750VA unit with trade in (smallest one that qualifies for trade in
credit) or $252 for a 1000VA unit (yeah, I don't understand that either.)
which would you do? This is an old UPS that I scavenged from a previous
employer something like 7-8 years ago, and at that time it was being
discarded because the battery was dead then, so it now could conceivably
be as many as 15 years old.
I want to go true online but worth the cost? Have had no problems with
my setup so far. (touch wood.)
replace "roosters" with "cox" to reply.
decision just got more difficult. I thought all "Smart-UPS" products
were true online, but they're not. However, they ARE the ones claimed
to have a true sine wave output, not an "approximation" of a sine wave.
The real true-online deal would be $985, so that's off the table.
I do like the idea of giving my stuff cleaner power on battery, but then
again, I'm thinking, just spend the $40 for a new battery, because
nothing's blowed up so far? (well, truth be told, i've been going
through wireless routers like candy, but previously I had same UPS
running my PC, which is still fine, so I blame the routers.)

And I like the idea of being a multi-millionaire. But I'm not, so I live
with what I've got.
APC UPS's are not "true online", and they don't make a true sine wave, but
you know what? The equipment does not seem to give a shit one way or the
I've had Alphaservers and all sorts of network gear running tickety-boo for
many years on cheapo APCs. Never an issue. If you have routers failing,
it's because nobody does pre-delivery testing anymore. Testing costs more
than shipping whatever came off the line and dealing with warranty claims
when they happen. Remember when hard-drives were each individually tested,
and the results written on a sticker /by hand/?
I think you can find better things to worry about. Buy a new anything-brand
UPS and be happy. Unless you're the sort that /likes/ things held together
with duct tape and chewing gum because it came for free. In that case,
you're beyond help.
If your UPS has a line-conditioner and software "Parachute", I
would replace the batt. You can get a 7.5 Ah gel-cell for $20 at
an alarm-parts supplier.
If not, I'd go for one with a line conditioner and the
I think the first question here is what's the overall mission
I haven't had a UPS on any of my home computers or routers. The
only problems I've had are if the power goes out, which is infrequent,
I might lose whatever work I had open. Even that isn't for sure, as
many apps do timed saves of the open documents, so you may
only lose the last 15 mins.
I've never had a disk corrupted by the power failing, or anything like
Nor can I recall ever losing any document, etc that I was working on
amounted to anything. So, I personally wouldn't spend $40, let alone
several hundred on any UPS.

I won't be without a UPS again. I have two because if the cable modem
and wireless router lose power even for a second or two it's annoying to
wait for them to reboot.

I gave been living in this house for alnost 20 years since it's built.
During that time total time for power outage was ~30 minutes.
I don't think I need a UPS, just another thing to look after. We have 3

You're lucky. Some places I've lived power has been pretty good. The
place I'm thinking of though, as often as not the clock on the
microwave would be flashing when I got home from work. The power
would never *stay* out for long - it'd just blip out long enough to
reset the clocks and reboot the computers. never went more than a
couple days without that happening at least once. sometimes it'd
happen several times a day.
For whatever reason, PEPCO seems to do a much better job than BG&E, so
I'm glad I don't live in MD anymore (for many reasons.)
I'm with you Nate, every piece of computer gear I have is on a UPS. I
had to reset the breaker last night when the electric heater warmed up
the breaker enough. Computer, cable modem and router never skipped a
a beat. :-)
About two weeks ago I got a memo saying that all equipment associated
with a PC should be on the same breaker as the PC. Otherwise would be
an unusual case but I'm sure it happens. Good advice for home
entertainment equipment too.
Consider yourself lucky... I went many years without a UPS for my
computer. Despite my rural location, we rarely have power outages. I've
always used high quality surge supressors, and backup regularly, so I
wasn't overly concerned about power surges either.
Unfortunately, power "fluctuations" are usually more of a problem than a
total outage, and I've lost both hardware and data because of them.
The typical situation is during wind storms where a tree falls on a power
line. It doesn't knock the power out completely, but cycles it on and off
several times a second, or drops the voltage way down (brown outs).
The first time it happened I lost a power supply. My system runs 24/7/365
so it could probably be said the supply was getting weak anyway, but the
cycling and voltage surges were too much for it and it finally died.
The second time the brown outs and power cycling occurred while data was
saving to my hard drive and it corrupted the drive. I had to reformat the
drive and (thankfully) restore from a backup. No physical damage that
time, but a lot of wasted time rebuilding the system.
We had a wind storm again a couple of months ago, and this time my
computer wouldn't boot up. I installed a new power supply, but it was
still dead. I pulled all PCI cards and got it to boot. Then I slowly
added them one by one till I found the one that had failed (thankfully it
was a tuner card I was no longer using anyway). Again, not a major
expense, but a lot of wasted time trying to track down the problem.
My computer runs non-stop recording TV shows, controlling our home
lighting, we use VOIP on the network for our phone service, and more. My
home business also relies on my computer being up and running at all
times. For me, the cost of a UPS was worth a little more insurance of
keeping things running when there are power issues. Or at least have
enough time to save files I'm working on and shut down cleanly.
I chose a Cyberpower CP1500PFCLCD UPS for a little over $200:
Of course, we haven't had any power problems since I hooked up the UPS,
so I don't know for sure how it will handle similar power problems in the
future. However, it has already recorded a few hundred "events", and
kicks in to even out the power when my laser printers drop the voltage
when they first kick on.

I have an enterprise level work station that I use and I get them cheap
from a company that sells medical office systems. When a customer
upgrades, the computer company takes the several year old systems back
to the shop, cleans out the hard drive and sells them. In 2009 I got
several of the systems for me and a few friends. All 3GHz P4 with
Hyper-Threading and they're darned fast. When new, the motherboards were
expensive and high quality. 7200rpm Barracuda SATA hard drive and a SATA
CD/DVD+RW along with a multi-memory card reader. Not the same low level
of stoutness you see in the consumer supply channel. The only one
I've had any problem with was the system I assembled for my friend's
wife who closed the box up in a compartment under a desk and filled all
gaps around it with papers and file folders. She smothered it during the
summer, poor thing. It could just be the power supply, I don't know yet
but I haven't seen any burned spots. I service point of sale systems
from time to time and the Dell, HP/Compaq and IBM/Lenovo computers are
not the same models for sale at Walmart, Office Depot, etc they're only
distributed through the business and corporate supply channels. These
computers are built with higher quality components and heavy duty power
supplies. I've noticed they'll take a lot of abuse without gronking.
Another item that is very different is the hard drive. The enterprise
grade drives are designed to hammer away 24/7 with a high MTBF ratings
and consumer grade drives are designed to operate with a certain number
of hours of operation per month in mind. The drive that came with my
PC is somewhere in between. Of course heat kills, keep the dirt out of
your PC and it will last a lot longer, I find some of the dirtiest PC's
in the cleanest of offices. :-)
I'm not sure what you would consider "consumer grade" equipment, but yes,
my home built computer has been running non-stop for over 5 years. I
usually upgrade my system long before anything fails on it's own. I select
many components for quietness and lower power consumption, which usually
translates to higher quality as well.
Except for damage caused from power surges/outages, I have not had any
hardware failures in many years (except for some faulty RAM I bought that
started flaking out in the first couple of weeks). Hopefully the UPS will
help reduce those rare failures.
Of course, something WILL eventually fail, or be damaged by external causes
(power surges, fire, theft, etc.). So, I'm rather religeous about backing
up routinely and swapping backups with drives I keep off site. I can always
build a new computer, but I can't replace one of a kind data (photos,
financial records, etc.).
Yep. I tell my customers "Hold my beer and watch this. Your computer is
about to elect a new Pope!"
Sure enough, giant clouds of white smoke appear. The angles sing, the saints
rejoice. God's voice (via the internet) is no longer muffled!
