I don't know what uninterruptible power supply to get. I have these parts for a computer. http://pcpartpicker.com/p/f6Vv99 I know I want to get one that is pure sine wave and want to spend less than $200. What is the best one I could get?
You also have the smaller CP1000PFCLCD for an MSRP of $170.
I'm not a big fan of Cyberpower though, their ethernet protection limits your plugs to 100mbps rather than 1gbps, which is a huge drawback for some people (myself included)
That system will probably need a 500-750VA UPS. Maybe something like the APC Back-UPS Pro or RS lines at 700VA/750VA or a CyberPower Systems CP850AVRLCD. Actual sine wave UPS will probably be outside of your price range, the best you can hope for is a decent approximation to a sine wave.
