Which UPS should I buy?

Hey there.
I've been having alot of Power cuts nowadays. And I've already lost one HDD, I don't want to loose more.

Below is my Rig's specs.
Can anyone help me by telling me WHAT TYPE and WHICH UPS should I go for?

Specs:
Gigabyte GA-P35-DS4
Intel Core2Quad Q6600 2.4GHz
Kingston DDRII 4GBs
XFX Nvidia 9800GT GDDR3 512mb
Cooler Master 600W PSU
USB Keyboard & Mouse
3 Internal SATAs (1x 250GBs, 1x 320GBs & 1x 500GBs)
2x Western Digital MyBooks (x 500GBs & 1x 1TB)
Cable Modem
Samsung SyncMaster 733NW 17" LCD
Creative SBS A200 2.1

These are the items I would want the UPS to support.

Really appreciate your help mates!

 

Well, a 1000VA UPS will give you plenty of time with your machine(almost the same as mine), more than 20 mins with a modem, router and 19" LCD widescreen. APCs are reportedly the best and most expensive. This is the one I have had for the last 5 years and finally need a new battery for, Ultra. Get a smaller one if you don't need all that time and they'll be cheaper too.

 

Although I have never used them I would second APC. I recommend you make sure you get one with online power.
