UPS Questions

[Robert4]

Hello,

A few questions, please:

a. Anyone know what the power consumption, max., would be for an iMac with the basic
screen (not the bigger one) in Watts (worse case) ?

b. Will have to buy a new UPS.
Have decided to go with CyberPower.

The latest and greatest seems to be UPS units with a pure sine wave output.
Certainly desirable, but realistically, how necessary ?

Anyone ever experience any differences between the conventional
simulated sine wave output and
their newer units with the "pure" sine wave output ?

Reason I'm asking is that the pure sine wave output units are "significantly"
more expensive for the same rating.

Thanks,
Bob

I have used both. Both do work and for the end user, it comes down to the price you are willing to pay. Having a UPS is going to be far more valuable than not, or waiting to buy a better one than what you can afford.

I was using an older APC Backups ups on my iMac that I'd got on sale. Then on either an amazon prime day or black friday, the CyberPower 1500PFC unit came on sale for such a good price, I bought a new one, and relegated the old ups to the family mac mini.

They say the true sinewave works better with the power supplies inside the iMac. But also consider that when you have no power conditions (about 99% of the time) the unit just passes the power coming from the outlet directly to the iMac. it is just when the power dips (brownout) or drops (blackout) that you are using the UPS battery. And then its how long on that? I would say that if given a choice between smaller true sinewave ups and a larger simulated, I'd take the larger ups as the batteries wear out over time so the larger UPS will last longer before the battery is shot. And I've been through many ups and replacing batteries is about as expensive as getting a new ups when it's on sale. They last about 5-6 years. Sometimes up to 8.

Thanks for thoughts, and time to write it all out.
Appreciated.

Any opinions on APC vs CyberPower "quality" these days ?

Some of the comments on Amazon, for both, are really scary.
Fires, etc. !

Happy Holidays,
Bob

I have had both. I have never had any real problem with either. I would stay clear of the small ones that look like a really big powerbar. those ones the batteries are total garbage and wouldn't last 3 years.

As I said in my post. Your best to buy what you can afford as having something most likely is better than having nothing, especially if your in an area prone to bad power.

I have bought off of Amazon and use the Camelizer to check the past price history for anything that I am buying. Living in Canada, I don't know what your prices are going to be for your part of the world. But for example the
CyberPower CP1000PFCLCD lists on Amazon for $205, but in October it was $150. I got the 1500va version of this for $157cdn in 2016 for black friday.
