Yikes, lots to think about! Measurements? Calculations? Waah?

I only need time to shut down my desktop PC if the power goes out. 10-15 min? It is a Lenovo workstation with a single Xeon and dual graphics cards. Drives many monitors, but I guess I only need to have one monitor plugged into the APC.

Ideally the APC will shut the PC down if I'm not there, but that's not so key as I (can remember to) close all apps when leaving - there's nothing I need to keep running overnight.

The NS-1350 is only $180. If that will do what I need, I'll spend that to save thinking time :-)
