I read thru the archived UPS thread but I couldn't fully get an answer to my question. My current UPS (Secure) provides around 650VA of power. Connected to this is: PC with a 750w PSU; Monitor; Airport Extreme and DSL Modem. However every time the power goes out, the PC and monitor shut off right away and is barely able to keep the Airport and modem alive. Exactly what power rating would I need to keep all of these alive for me to a) shut off the PC and b) enjoy the internet for a little while? I've been looking around at APC products but the higher the power, the more it becomes cost prohibitive. So are there other reliable alternatives that cost less?
