No not Brown

I am looking for a backup in case of black out/power failure. I have seen a few mentionings of other users using a UPS so I thought I'd ask her for good brands to look at. I know PC manufactures(corsair,EVGA, ect.) But this is new territory for me.

Any help is welcome.

hmmm, depending on your power needs, it can be costly. The one I have I have it set up to send me an email when the power is cut or any other alarm.
APC Smart-UPS 1000VA LCD RM 2U 120V pricey but worth it. 3 year repair or replacement and 2 year on the battery waranty. 700-1000watts, about $600 US after taxes.

Oobievision is right it depends on your power needs. APC is king of the hill but I went for a lower cost unit called Cyber Power it was about half the cost of a comparable APC unit.

I have had it for 3 years now and saved me 2 times. It's a weird experience when the lights go out but your computer is still running. I looked around to see if someone turned the lights off.

It should be noted that UPS in the sub $1k range are just to give you time to properly save files and shut down properly. Depending on what all you are powering you might get 15-30 minutes on a low cost unit (sub $1k).

I am looking for a unit to give me around 10 minutes of power to save work and halt renders ect. Not looking for hours of working while the lights are out. It needs to be cheap and relatively small. if I wanted to spend over 1k I know people that can setup actual battery backups for around that.

I ended up going with this one last year:
http://www.amazon.com/gp/product/B00429N19W/
It has a pure sine wave which can be important for some computers. I've been pretty happy with it so far, although I haven't really had to rely on it during a blackout yet.

Thanks! That looks perfect! I don't need to power in the event of power failure. I just need enough time to save. One review says with everything including 3 monitors gives him 10 minutes of grace time. If I can't save my lightwave files within 10 minutes I don't deserve access to a computer.

I have an Evolutions S 3.0 kva, it's 90% efficient so has an output of 2700 watts. It can run my 6 computers & 3 monitors for 20 minutes with 2 extra battery modules, load is about 2300 watts when rendering. & it's best not to run the batteries down to less than 30%. (A UPS will say for example that you have 30 minutes but in reality you only have 21 minutes to 30%!)

The cheaper UPSs are only about 60% efficient, a typical 1500 VA UPS & will only have an output of roughly 900 watts.

So to get your 10 minutes for 3 computers you will need something much larger than you think!

The Evolution S 81708 1250 VA will give you 1150 watts output. But you will only get 15 minutes in total to a flat battery, so about 10 minutes to 30% at a 590 watts load. If that's not enough wattage you can add another battery.

The next model up 81711 1750 VA 1600 watts, will only give you 653 watts for 15 minutes, 10 minutes to 30%.

One extra battery will give you about 4 times the minutes at heavy load.



Edit:
Just found this is an old model!

& most UPSs don't have surge protection! So it's a good idea to get something equivalent to this for surges & lightning protection:
