APC for iMac mid 2011 + two ext HDDs

This was originally posted on APC forums on 8/11/2013


Having done a little research I am left a little unsure about the way to go. My situation is that I have an iMac mid 2011 model with a 27" display, but I plan to get the new Mac Pro when it comes out (http://www.apple.com/uk/mac-pro/). Naturally the Mac Pro will consume more power, one would imagine anyway, it's a beast of a machine. The forum I have been following closest details the issue of "simulated" vs "sinewave", and that I'd be better off going with a "true sine wave unit" for a Mac unit. Not sure what that means, but it seems like sound advice as it's mentioned often enough in other threads.

The forum recommends two units, one which lasts for ten minutes: the "APC Smart-UPS 1000VA LCD" at 495W, the other lasts for around three times as much: the "APC Smart-UPS 1500VA LCD" with a maximum load of 980W.

I do not mind paying more, but would like to be able to use it when I get the new Pro. Based on the existing Mac Pro, how much time would I be looking at if I were to get a "APC Smart-UPS 1500VA LCD"? I will probably max it out at 12 cores, lots of RAM and have a 4K 27" cinema display, I will also have two external HDDs (each connected via a Thunderbolt cable) and need a little help guestimating the overall power requirements?

I will wait until the Pro is released of course, but just to get an idea I would like to know where things stands right now. I could always get the 1500VA now and upgrade later to another one I suppose, that being my long term purchase I am also interested in the cost of replacement batteries.

One thing I would like to know is if the UPS is noisy or not, apparently it has it own fan..
