The first two depends on your PSU maximum power draw. The third is about personal taste. The fourth should only matters if you are running delicate and sensitive machine. Modern PSUs do NOT need pure sine wave UPS (it would be nice for them, but pure sine wave UPS is too expensive). Keep in mind you should ONLY hook PC and 1 monitor into UPS's battery backup. Any other things like printers, external burner, etc should be hooked into UPS's surge protector. Also you need to replace the UPS (or the battery inside it if you can) every couple years.
What would be the difference of VA and Watts? From my College degree, VA is "True Power" and Watts is "Real Power" but how does it apply to UPS and Computers?
What would be a most common length of time of run after power outage for most PSUs?
How much difference is a pure sine wave UPS vs. a non-pure sine wave UPS? Power coming from our home electrical outlets are pure sine wave, right? Does that mean that when you connect a non-pure sine wave UPS, it "distorts" that pure sine wave coming from the outlet?
What is the difference of the Surge protector port of the PSU vs. the battery backup ports? Why do other not-so-important computer peripherals need to be connected here?
Is Cyberpower better than APC?
