    I'll be moving to the Caribbean for a few months and taking my iMac with me, and there are daily power outages there. The building I'm staying in has backup generators but they take 10-15 seconds to kick in.

    I'm looking for a cheap UPS that will withstand those 10-15 seconds so my power supply doesn't fry. I've read several threads about how "pure sino wave" UPS's are the way to go for newer iMacs, but I haven't found one under $100 and many reviews indicate they're able to get 45-60 minutes on various UPS's in the $100-150 range. Since all I need is 30-60 seconds, that all seems like overkill for me.

    Any suggestions would be appreciated.

    That's the one I bought for my business. Works excellently.

    I fully understand the need to save money. But trying to go cheap on a UPS can very well be a hugely expensive mistake.

    I'd suggest you go with a known brand that makes a solid UPS. You said your iMac will be in region with flakey power. One outage, followed by a surge or two as the power restores, and you may find out (too late) that your bargain UPS failed, and that money you saved just went up in acrid-smelling smoke.

    I had that one, and when the UPS kicked in there's a noticeable buzzing from the iMac PSU. This is due to that one not being pure sine wave. Lots of debate from both sides, but it's probably worth spending a little extra and getting a pure sine wave UPS at this point if you don't have a UPS.

    Get this one, like many of us have. No buzzing from the iMac when the UPS is kicked into gear:

    Thanks everyone for the responses, they've all been helpful.

    I was planning on getting a simulated sine wave Cyberpower, similar to the APC recommended earlier in this thread for $50-60.

    Is the only difference between pure and simulated sine wave that there is a buzzing sound? Since it will only occur 10-15 seconds a day before the building's backup generator kicks in, that's not a big deal to me. I read on other amazon reviews that some of those lower end APCs don't work at all for newer iMacs, and that's what has me concerned.

    I do agree with you. I replaced an APC 750VA with the Cyberpower 1500 not too long into the tenure of my new iMac. I was attempting to be responsive to the OP, who indicated an aversion to spending what you and I spent on the Cyberpower unit. ;)

    Since some stepped sine wave UPS's don't work at all with some power supplies, showing that there is indeed a compatibility issue, I would worry that a stepped sine wave unit would work *most* of the time. Spending another $60 would be well spent peace of mind, at least for me.
