Kill-a-watt (I've got one - its ok, but leaves a LOT to be desired) and Watts-up Pro (never used one, but I've heard of it) might be great for measuring operating current, however if you have a large number of devices, beware the sum total Inrush current requirement. I doubt those two devices are sophisticated/sensitive enough to account for Inrush current (in fact, I know the Kill-a-watt doesn't do it in a way that you can record it).
http://en.wikipedia.org/wiki/Inrush_current When it comes to measuring power, if you're serious, you need something along the lines of a Fluke 330 series clamp meter, IMHO. http://www.myflukestore.com/crm_uploads/making_accurate_inrush_current_measurements.pdf Just my $0.02.

We need to size a new UPS. Any suggestions on how to get accurate readings for our current power consumption?
