CyberPower UPS for Late 2012 27-inch Core i7

[Hexley]

I am looking for a UPS for a Late 2012 27-inch Core i7 and I see recommendations for a CP850AVRLCD from the CyberPower Intelligent LCD Series.

Is this sufficient? I worry that the flickering I was experiencing is from the worsening quality of power from the grid.

Apple skipped the Late 2012 27-inch Core i7 power consumption rating. So I am stating the max power consumption from the 2011 model (200 W) and 2013 model (229 W).

Goal: Clean power to the iMac, battery power for at least 10 mins and auto shutdown on the last minute of battery life.

is your iMac currently connected via a surge protector?

How old is the building you use it in?

I have had the CP1000 for a little over two years. I've got a mac mini server, external drive array, router and modem connected to it.

OS X recognizes it with no issues and the mini shuts down when an outage has occurred. It has been able to provide wifi during a few long outages as well.

I use the Cyberpower pure sine wave UPS on my computers here.

I got the CyberPower CP1500PFCLCD for my new 5k iMac, which hasn't arrived yet.

It's more than I need, but it was on sale for $149.95 so I had no choice.

It's supposed to arrive tomorrow

I think I have the same battery backup on my Mac mini. Almost had it a year now. I have the mini and 3 external hard drives connected to the battery backup and it lasts a long time during a power outage.

I don't like the fact that the big glowing blue power button on the front of the unit shuts the whole thing off with a simple press, rather than a press and hold like the APC battery backups I've used. Not really an issue now after rearranging my setup to hide the battery backup away from poking fingers...

swordfish5736, iMac was attached to a powerstrip that I swapped out with a newer one (still experienced some flickering but lesser).

Building I am in is about 2 decades old.

What are the advantages of pure sine wave UPS over a regular UPS?
