UPS Battery Back Up for iMac--Advice on Purchase

I have an old APC Back-UPS ES 725 that has served me well. It has started to fail in that it is not holding a charge (at times) and has alarmed a few times for no apparent reason. It is old enough that I don't want to trouble shoot it by replacing the battery or trying other things. Right now it is disconnected and in this downtime I have experienced two brief line power outages that have shutdown my iMac. The iMac is fine, so far, but it is time to get another UPS.
APC's website and reviews of their products still leave my as confused as I was when I bought my old UPS 8 or 9 years ago. But I think I've narrowed it down to either an APC Back-UPS 750 or a little more expensive APC Back-UPS Pro 1000. The 750 has a flat profile and the 1000 has a more vertical profile. I think the 1000 will allow more run time on the battery. The 1000 has a display that may make it a little easier to use than the 750. They both would have enough wattage for my needs as far as I know. I just can't really determine what the major differences are betweeen these two from the descriptions. I don't want to buy more than I need but would spring for the 1000 if it has more to offer.
Any thoughts on the differences between these two. I think they both provide a stepped sine wave and I don't think I need the more expensive pure sine, or do I?
Thanks,
Steve M.

The APC Back-UPS 750 will be more than adequate for an iMac plus a backup hard disk drive. You did not indicate which model iMac you have but the small one should run for over 30 minutes on the UPS alone, the larger one about 20 minutes, more than enough time to conduct an orderly shutdown.
Do not install any software, just plug in its USB cable. OS X already includes software that will monitor the APC UPS's state of charge and can be configured to shut down the Mac using parameters that you configure.
Cyberpower is another manufacturer worthy of consideration.
A pure sine wave UPS is not necessary.

Dear sir while using the Internet 3G on my phone after using for 15 min my phone back panel getting hot every time after closing the inernet it becomes normal cool plz suggest me what to do & for 3G use I'm getting battery back up for 3 to 4 hrs plz help

Dear sir while using the Internet 3G on my phone it getting hot at backside specially back panel below apple logo and after stopping the use of Net it becoming normal also for 3G I'm getting battery back up for 2 to 3 h
rs only plz tell me what to do plz reply it is normal or any problem with my phone

Please don't respond with useless comments. I've already addressed the fact that my screen was broken a few months ago. My phone may or may not be broken beyond repair either way, as I said before I can't afford a new phone. It's a strange problem because from what I can tell no one else has posted the same problem anywhere I can find. Don't be a dickhole.

How to get support for a UPS (battery backed power supply)?

According to all documentation, there should be a tab under "System Preferences/Energy Saver".
However in MAC OS X 10.5.6 there are only Sleep and Options tabs.
Any idea?

HI Moshe,
Try a different USB port.
Here's a thread that might help: http://discussions.apple.com/thread.jspa?threadID=1484450

Which ups is the best for imac ?????

I have imac 3.06GHz core 2 Duo, memory 4GB 1067 MHz DDR3,
I want to buy ups, that contains auto closed, and have voltage stabilizers.
which is the best ups for my imac?
thanks a lot

There is no best, you have to assess in addition to the Mac what else will be plugged into it and what other needs you may have. For brands I'd recommend APC, you can visit there website and they can help you choose one that comes closest to fitting your needs.

Ups transfer time needed for imac 27

I have been given the royal run around by Apple "Genius" employees and lied to by Staples techs.
Can anyone tell me the proper UPS to use for an iMac 27? And please give me the reason why.
I would greatly appreciate the help.

Dear Rkaufmann87,
I have been performing my due diligence for 2 days. Without due diligence, I would not have discovered that iMacs have different power shut down times than other units. It IS Apples duty to inform me of the amount of time in which the computer takes to detect a no power event. Apple Senior Tech Joe advised me that any UPS which provides a transfer time under 1 second will work appropriately for the iMac 27. Due diligence also uncovered the fact that APC does not include transfer times in all of its documentation for each UPS unit. It takes emails to very skilled APC techs to get to the proper answers in that respect. Thanks for your input.

UPS system for iMac G5

APC has a BackUPS ES series which is an affordable line (compared to the other models). I emailed APC tech support and they recommend that I get the APC SmartUPS 750VA. Here's a reply from APC tech support on why BackUPS ES isn't recommended:
"For the Mac system, they have very sensitive power supply box. If you have a Back UPS to back up your iMac, it is really not compatible as the UPS does not supply a sine wave at the output supply when its on battery. This might be dangerous for your Mac if the UPS is supplying power to your Mac when on battery mode."
My problem is that the SmartUPS 750VA is too expensive. I'm thinking of just getting the SmartUPS 420VA since the iMac G5 has a maximum power consumption of 180W. So the 420VA should give me enough time to shut down in the event of a power failure (I will not be plugging anything else). However, APC tech support then told me that 420VA would not be enough because I have to account for the start up power consumption. They said that the startup power consumption for an iMac G5 is around 400-500W, so I would then be overloading the SmartUPS everytime I turn the computer on. Does anybody know if the iMac G5 really takes 400-500W to power up? But even if it does take 400-500W to power up an iMac G5, would I be correct in assuming that it shouldn't be a problem? I say this because I will only be powering up my iMac whenever there IS electricity. So I won't be getting power from the battery backup whenever I do that. I just need the backup battery to shut down in case of a power outage, and not to turn the computer on. So why should the UPS get overloaded?
Also, can anyone else recommend any UPS surge protectors for their iMac G5's? Preferably one that had Automatic Voltage Regulation as well.

I've been running an APC BE 325 on my iMac G5 for the last 8 months. While it provides minimal back up time (6-7 min.) the audible alarm gives me time to shut down properly. Got it a WalMart for $35.
More importantly to me, it affords a greater degree of lightning protection. Here in the Tampa area we tend to get very short blackouts during thunderstorms that last a second or two. Those combined with lightning voltage spike give me reason to worry about the quality of my power supply
I would guess APC is just C.T.A. when they say the iMac powersupplies are fickle. They don't want any blame for any of the known iMac G5 power supply problems.

Provided that model gives you the runtime you want it is fine.

UPS for imac 3.4Ghz i7?

Hi,
I have a 3.4Ghz i7 imac 27"
I'm looking for a UPS..
I've been reading various comments on Amazon about APC UPS's and the new CPUs and there power requirements.
Would also like to power my Pegasus R4 with the same UPS
Does anyone have any recommendations for a UPS?
Apolgies if this is an over worked topic! :-)
Many Thanks,
Steve

Thanks for the feedback.
APC is great, I've had one before with my old G5.
Can I refine the question slightly?
The question: Do I need a smart or a non smart UPS given the power requirements of my imac 3.4Ghz i7 and is the product mentioned below man enough for the job?

I like the idea of auto back-up for my new iMac, Ipad and PC Netbook, particularly if I can access all files and data stored on any device. But I have a Conceptronic router. Will Time Capsule work with this and how?

I like the idea of auto back-up for my new iMac, Ipad and PC Netbook, particularly if I can access all files and data stored on any device. But I have a Conceptronic router.
1. Will Time Capsule work with this and how?
2. Can my printer USB be plugged in and then shared between the devices?
3. Can I create a network and how?
4. What happend when a visitor logs onto my existing wireless router?
I'm new to Macs (well a returning user having started with Mac Plus!!) and not very technical. Any help / advice will be much appreciated.
Ray

The key to what you seem to want to do is to be able to get Apple's Time Capsule router to "join" the network that your Conceptronic router. I believe that works with some third-party routers, but I've never seen a list of those that work in such a configuration and I have no experience with Conceptronic equipment.
You might be better off with a Network-Attached Storage (NAS) device instead of a Time Capsule.

APC UPS for iMac

I posted this in another thread, but since I have a new Q I am posting it again so it is tracked properly...I have 3 brand new iMac (24 inches, 3 GHz) and 1 MBA in my small business. Living in Seattle's suburbs, we have several 2-3 seconds power outages several times every winter. The issue is not if the UPS is 25% or 100% of the price of my iMac as the time we spent working on something is worth much more as we charge $200/hr to our customers with our consulting service. Last night I lost one file that got corrupted. It will take me 3-4 hrs to do it again... so I am buying my UPS right now! Before I make the final choice, can somebody confirm me if the power management feature will work with the BE750G? Pricing is not much of an issue. anything in the $90-$250 will do it for us as we lost more than that last night. I found the BE750G for $86 at Amazon and the SUA750 for $270. I really need the power management functionality as we leave the Macs powered on all the time and we are not always there to start a manual shut down.

I hate to say this but APC phone support is extremely poor (or t least the reps I got to talk to). First the sales rep told me the 750G was a discontinued model... when I told him I was looking at that on THEIR web site he acted surprised... so he moved me up the chain to second tier TECH support. Second tier support said that for iMacs the recommend smart UPS because those are better, but could not articulate why it was better (other than saying that they were more expensive because those units are better , He had no idea about switchover times, and I swear I am not making this up, he asked what version of Windows I was running, (I guess a valid question on Intel based Macs) etc. So after that experience I am very leery of trusting their advice and rather learn from a fellow iMac user that is indeed using either a 750G series or the most expensive Smart UPS 750 and confirm me if indeed switchover is fast enough and the USB connection will work well and start a shut down process if needed...
Thanks for the help

UPS suggestions for iMac...

Just got an iMac and I need to make sure that I'm protected from power issues etc. I want something better that a surge protector power strip. I'm thinking of one of the APC UPS (battery backup).
Anyone have experiences with the APC UPS on Mac's? Or does anyone have other suggestions for having a UPS?
Thanks,

B60Boy,
I found an APC configuration tool that I think you will find useful. You can input what your needs are and it will suggest some UPS choices for you.
http://www.apc.com/tools/ups_selector/
I did a dry run based on what I thought your needs were and it came up with 3 different selections. Give it a try and see if it answers your question.

APC does provide a list of UPS's in their website, I would recommend looking it over at:
http://www.apc.com/products/family/index.cfm?id=29
Perhaps you will be able to locate one that closely fits your needs. I believe only plugging in your iMac is a short sited solution, my recommendation would be to protect certain critical peripherals such as backup hard drives. They can be as important as teh computer. Devices I would omit are items such as printers, cameras, modems etc...

But it really should not matter.. so just try it in situ.. press and hold the reset.. once it starts up, it will return to default IP, 10.0.1.1 the PC should then be able to find it via the airport utility.
If not drag it over to the Mac and plug in there by ethernet.. or since it is a laptop, really should not be that difficult to drag the Laptop and plug it into the TC.
Important thing is to get access to the TC.
The Mac if it is running lion, then you MUST download and install 5.6 airport utility to do anything useful.
