Hello, I'm trying to find a good, cheap UPS for my system. I have a 2009 base quad core, 2x SSD, 3x WD HDD, GTX285, and 2x 24" monitors. I just need it to sustain the system for a few minutes in a power outage so I can shut down properly. I also use bootcamp, so something that works flawlessly in both windows and OSX would be super. Something with a super easy setup in both would also be nice.
