UPS help

I read through the FAQ on them and still lost. Can you guys help me choose a cheap ($$ wise), powerful enough UPS to keep my computer system safe and clean. Here's my set-up:

CPU - AMD Phenom II X4 955 BE
MOBO - MSI 870A-G54
RAM - G.SKILL Ripjaws 4GB DDR3 1600
GPU - XFX HD 5830
Case - HAF 922 (2 200mm, 1 - 120mm fans)
HDD - Samsung Spinpoint f3 1TB
Optical - Samsung SH-S223C
PSU - XFX P1-650X-CAG9 650W

Monitor - 40" samsung tv (which i want hooked up to battery most likely)

I want it to be able to shut my computer down automatically if I am not by it. And a minimum 5min battery time. I want to stay under $100 if possible. But if i must can go to $120

This is one that I am looking at but dont know if its anywhere near the specs I need.

Tripp Lite ECO750UPS

Any suggestions?

The UPS selection should be done similar to a PSU selection.. Add up the wattage ratings of all the components drawing power from the backup and then select a UPS with a slightly higher wattage rating (in any case, do not connect your speakers to it).. The brand becomes important too.. APC is the most trusted UPS manufacturer.. I don't have much knowledge with Tripp Lite and the link does not seems to work for me.. But if it is 750VA then i guess it'll be slightly pushing if you plan to connect your monitor also to the backup..

CPU - Idle: 148W Full: 236W
MOBO - ~20-40W ?
RAM - 2-5W ?
GPU - ~29-207W
Case - (2 200mm, 1 - 120mm fans) not worth calculating?
HDD - 4.9-7.9W
Optical - ? small im guessing and not worth calculating
PSU - XFX P1-650X-CAG9 650W

Monitor - ~247W

So ~349W avg "running"
And ~500W fully stressed for the computer
The monitor/tv ~247W "running"

And that leaves about 600W "running" (because I doubt it will be running fully stressed when I need the battery)

With that in hand, I'm guessing I should be selecting a ~600W but what about the VA?

They say both for most UPSes - like in the one you linked, 750VA and 450W. Go off the wattage number, despite the fact a Volt amp actually is a watt.
