Which is the best UPS for my 2011 iMac?

I was using my iMac tonight and it randomly shut off. My APC UPS started beeping wildly. I reset it and the replace battery light was on so I think it is pretty much dead. It went 5 years so thats nice though. It was a 800VA model which was nowhere near full.

So I'm looking at a new UPS unit. APC lately seems much more expensive then other brands, and I had too many kernal panics in the past with that power chute software. I'm thinking of trying a Cyberpower model instead. 800VA or 1000VA depending on how close the prices are.

My concern is sine wave vs simulated sine wave. I have a 2011 iMac (22" Intel Core i5, 16GB ram, 1TB hard disk). I won't be running on battery power much, it's only in case of emergency. For example if I'm using the system and the power goes out during a major rain storm. I'd like to avoid the whole buzzing issue I hear about online, and any other issues that might creep up.

What would you suggest? If the difference was small, I'd go for sine wave instead of simulated. But if it's $50 to $75 or more, I'm starting to lean towards simulated sine wave.

I'm currently considering the Cyberpower CPR1000AVRLCD and the CP1000PFCLCD. My unit that died was a APC Back-UPS RS 800.

iMac, Mac OS X (10.6.7), 21" Intel Core i5 2.7, 1TB, 4GB Ram

APC is a fine brand and probably the most recommended on these forums. One major error I see you made is to install PowerShute, it's simply not compatible with OS X and should not be installed. You should contact APC Tech Support for instructions on how to correctly uninstall it. I think once you do if your KP's are related they will go away. You should handle this first, don't just trash the software, that will not get rid of it. You need to follow APC's uninstall instructions, I know because I found out the hard way.

If all that is wrong is the battery has died then simply get a replacment battery. You can buy replacements from APC or from a battery distributor, I've even seen them on EBay. They're about like car batteries, when they go dead you replace it.
