[RECOMMENDATION] UPS Device for System and Peripherals

I'm in the process of putting together a pretty high end system, and I want a solid UPS to keep it healthy in the event of a power failure.

I am not concerned with the battery life all that much, as I don't leave it on when I'm not around. Essentially 5 minutes would be sufficient, although longer wouldn't hurt.

By rought calcuations, I want about 7 outlets - will have to double check as I may want to go with 8 or 10.

Here is a run down of what will be plugged into it:

  • PC
  • Two LCD Monitors - 2007WFP's
  • HP AIO 3055
  • Cable Modem
  • Linksys RVS4000
  • Linksys WRT54G
I suppose I could go without the network hardware. The RVS4000 is what I would really want to protect since I bought that. The Cable Modem is leased and the WRT54G is from my job so they would replace in the event of a failure.

I have looked at a few briefly - I think my main question is this. Due to space constraints atm until I move, I can't keep things very far apart. How much of an issue is the EMI these puppies give off (similar to subwoofers), wrt how it can impact my monitors, tower and everything else?
I think I remember the Buffalo or Trust website having some wattage calculator to help you work out how long a specific UPS might be able to keep you running for.
Most "UPS" are really "BBS". There won't be any significant EMI from a BBS since it uses no power unless main power fails. When power fails nothing else will be working so interference doesn't matter.

You definitely want the network hardware and anything else plugged into the PC powered by the UPS. If you don't a power spike can propagate through the unprotected equipment and knock out your expensive PC. That includes printers, dial up modem/PC Fax, amplified speakers (all of them even 7.1 devices on the other side of the room). Remote speakers are a serious issue unless they use fiber optic lines to carry the signal if you have to run extension cords across the room for power.

You will need a 1000W (1200kVA) backup system for all that hardware. I assume it will be a high end dual or quad core CPU and SLI video. If you have a large HD array 1200W/1400kVA would be better.

The long version:

Who has the best deal (price/warantee/features) at any given time changes. You'll need to research current products.

Also Hi EP and people. I found this place again while looking through a oooollllllldddd backup. I have filled over 10TB and was looking at my collection of antiques. Any bids on the 500Mhz Win 95 fix?
Any of the SP crew still out there?

Impressed you have kept this alive this long EP! So many sites have come and gone. :(

Just did some crude math and I apparently joined almost 18yrs ago, how is that possible???
