I notice lights in my room sometimes dim or flash and thought about it was due to unstable electrical flow or whatever reasons.

Any ideas on what brand or model you guys recommend?

Appreciate any input.

I purchased the CyberPower pure Sinewave UPS 1500VA.......
I use it on my iMac, external drives, router, and security cameras. A smaller unit like the 850VA would be more than enough for just an iMac and is cheaper.

I have the same unit as Buerkletucson does, and it's been solid. It's running 5k iMac, OWC 4 bay TB enclosure, and a handful of USB3 backup drives. Never any problems. It's a good unit.

Also have the exact same unit and it's super silent even when it switches on after a power failure unlike some other units that hum like a straining transformer. You can find deals on this for about $150 or so on Amazon.

I have this exact one, works great. We have our basement freezer on the same circuit and whenever it kicks in my desktop lamp next to my computer dims. I didn't wana risk a three thousand dollar piece of hardware getting problems so I got the 1500. I also live in the country and our power DOES drop out many times during winter, it would be nice if once the power goes out my computer can sit idle for an hour or two before I need to actually turn it off properly. It's saved me a few times already, highly reccomend.

Only heads up... it's big. Like a vertical shoe box so make sure you have room on your floor!

I just took a look at this UPS and decided to buy it.

Now, it comes down to what size of it to buy and that if you can help me select one.

This UPS will be primarily used with iMac 27 5K and a pair of bose computer speakers as well as 3 external storage (small ones).

Will 850VA be enough? Is it worth it to buy 1350 or 1500?

Thanks for the help.

The 850 is big enough for the iMac itself...........
But with the other items you mention I would go larger.

Sucks to get one that is to small and has limited capacity and run-time.
I'd get either the 1350 or 1500.

The price difference between 1350/810w and 1500/900w is $35. Is it worth to go bigger? My usage for now is iMac 27 5k i7 and m395x, Bose computer speaks, iPhone iPad charging, and 3 external hdds. Will 1350/810w be enough? I don't really mind about power outage as in my area it is very rare. The primary reason I'm purchasing a ups is to prevent unstable electrical flow damage the computer like I said in my first post that dimming/flashing lights and so on.


Thanks for helping out.

No problem....

I don't want to spend your money..... :p
Lets put it this way..............if it were me, I'd go with the 1500VA unit.
Any expansion or added equipment in the future you will have adequate capacity with the bigger unit......and for the price difference I feel it would be worth the money.

I really like the pure sine-wave unit as I also use mine to power my security cameras/DVR.......the noise from a normal chopped power unit is terrible. I wouldn't think it would be good for a computer either.
CyberPower has done a fantastic job with these pure sine-wave UPS systems.

It's hardly any extra to just get the larger battery. So be like nike and just do it lol
