5 out of 5 eggsTrue sine wave

Pros: Unlike square-wave or stepped-approximation waveform units, this one will keep a quality PSU (like my Antec SG-650) happy; these PSU's will shut off if fed one of the other waveform types, so you're NOT protected if you have a cheap UPS.

Cons: None of the outlets are spaced for transformers.

Other Thoughts: Web-based management interface did not work in Firefox, but works fine in IE8. Windows 7 recognizes it anyway though.

5 out of 5 eggsbest in class UPS for the $

Pros: I have three of these, and have owned them for at least three years. They have more than paid for themselves.

Consider a UPS the equivalent of insurance. There are tons of brownouts you will never know about that will damage your power supply and downstream components. The UPS prevents all those headaches.

To my knowledge, this is the cheapest UPS that provides true sine wave conversion.

I have this running on Windows 2000 machines and OpenBSD servers.

For BSD/Linux users, please see:

to get your machine talking to the UPS.

Yes, I buy a replacement battery every couple years. They cost about fifty bucks. The satisfaction of seeing everything on my network up & running during local power outages more than pays for the UPS & batteries.

I don't know what other reviewers are running, but I easily get 20+ minutes runtime from the UPS -- one load is two LCD 19" monitors, KVM, cable modem, router, and computer. Another is a BSD server w/ 5

Cons: APC support of Linux/BSD would be nice...

Other Thoughts: Are some of these reviewers trying to connect their laser printers to the UPS???

2 out of 5 eggsQuality UPS but specs seriously overrated

Pros: Good overall quality, smart signalling via USB or serial cable, optional network management card available.

Cons: The real output power capacity is much less than the rated 500W.

Other Thoughts: The website lists estimated runtime at full load (500W) as 5min. This is completely unrealistic. The truth is that even at 400-450W (which is less than 90% load) the runtime is zero (!), i.e. the UPS turns off the output power immediately after mains power is lost (which of course defeats the whole purpose of the UPS). And this was with a brand new unit. I spent many hours on the phone with APC, trying multiple firmware upgrades, runtime calibrations and other tests and they finally admitted that their UPSes cannot be run close to their rated power. From my experience it can't be reliably run at more than about 300W.

3 out of 5 eggsAlright except for the batteries

Pros: Seems to do what it is suppose to. AVR trim/boost and sine wave is nice. Was the only UPS I could find that could keep an old buggy Tagan power supply from shutting off when switching to backup power.

Cons: As other reviews here hinted at, the batteries seem to wear out much faster than they should. When I first got the unit the change battery light came on within 6 months. This despite running a very light load on it at about 25%. Within 1 year the battery was completely dead and it could not stay on backup power even with nothing connected. At about 16 months I had the battery replaced via APC warranty (experience was good). The replacement has lasted longer at about 18 months but now the change battery light is on again and I still only have a 25% load on the UPS.

Other Thoughts: I have older UPS's that more than 5 years old and still running on the original batteries. They don't have as much reserve power as a new battery but they still work. For some reason this SUA750 seems to kill the batteries much faster. Overall an average product, not bad but not great, three eggs.

4 out of 5 eggsPretty Good

Pros: Extremely good, long lasting, high quality UPS, APC makes quality hardware and bateries, easy battery changing and a pretty nice feature that if you do need to change it, you don't have to shut anythign down, its hot swapable.

Cons: Be careful, I drained mine and then it charged too fast and the batteries expanded or something and now I need new batteries. Not quite sure why, but the cells are about to break open, and the batteries melted together. Its fun to look at, but not to mess with.

Other Thoughts: I think the batteries dying was my fault, these batteries are usually pretty good.

5 out of 5 eggsNice UPS

Pros: True Sine Wave Output; Excellent Build Quality (Metal Case); External Battery Disconnect Jumper; Nice Array Of Informational LEDs On Front Panel; PowerChute Business Edition Monitoring Software Provides VERY Detailed Information; I Like The Short "Bread-Loaf" Form Factor

Cons: PowerChute Business Edition Is Not The Most Intuitive Software To Work With.

Other Thoughts: I just re-built my system using a 100% passively cooled case that has an integrated fanless power supply. The power supply has active power factor correction, and power supplies likethis can sometimes respondpoorly, or even be damaged by UPS units that produce a square wave (or whatever marketing chooses to call it) AC signal. I read a few "horror stories" about this, and decided it would be worth it to get a UPS that generates a true sine wave output when it is on battery. This product does that. Also, unlike other UPS units I have tried recently, this unit does not produce any audible "hum". You have to literally stick your ear on the case to hear anything, and even then it is pretty hard to hear anything. PowerChute Business Edition software is a little cumbersome to work with, but provides highly detailed information that is very useful. The marginal additional cost for this server-grade UPS is well worth it. When you consider what this product delivers, it's a great value.

5 out of 5 eggsGreat UPS

Pros: I have had this UPS protecting a server and networking components for over 4 years now with no problems. The replace battery light came on for the first time today. Over the past 4 years the UPS has had to take over power over a dozen times, and every time it did exactly what it was supposed to do. Can't beat that.

Cons: Really, really heavy.

Pros: Seems to work well, software is better than other manufactures I've delt with.

Cons: Replace Battery Light came on right after 1 year.

Other Thoughts: Battery should last longer...
Now it is goint to cost me almost 1/2 the purchase price to replace battieries.

5 out of 5 eggsAPC Smart UPS

Pros: After a complete system rebuild, I deceided it was time for clean power in. I LOVE THIS UNIT. Available features are great. You can pull graphs that will tell you how well the system is functioning as well as monitor the inbound and outbound power levels/spikes. just knowing it supplies very very clean outbound power is enough for me.

Cons: None so far. This unit arrived and was put in service under 15 minutes time. Batteries were 90% charged and setup instructions were easy. I WISH I HAD BOUGHT THIS UNIT 3 YEARS AGO.

Other Thoughts: If you want to supply clean power, don't settle for a cheap UPS. Spend a little extra and utilize the features that are available on the APC SMART UPS Backups. You won't regret it!

5 out of 5 eggsA Must !

Pros: 2 of the most overlooked items in every PC seem to be the most important - PSU, and in this case, a UPS. I needed to do something for our frequent power losses we were encountering. From 10 seconds to 5 hrs, 5 & 6 times a month for 2 yrs. I also found out my neighborhood was on a generator while SDG&E was working. Bottom line, this UPS doesnt even blink at the erratic power, it simply "clicks" to let you know it switched to the Battery - cleanly and without a hickup from my PC. It's a solid, reliable, nice looking, "TRUE" sine wave UPS that does it's job - filters, protects, and provides Backup power for unruly and unreliable power conditions. If you can spend $300 on a GPU, or $100 on lights for your case, by all means protect it with this UPS so you can atleast shut down your PC properly if you should lose power. Dont forget this UPS provides a "STABLE" line voltage to critical components as well.

Cons: The "Special" USB cable that costs $xx+ , you cant use any Generic, just a APC supplied cable. It might be the same for the serial cable as well but I dont remember.

The Powerchute software was terribly faulty so much so that the tech determined he couldnt get the "Server" or "Console" setup and could I get by with only the "Agent" running. It didnt bother me but for others they may need the extras and this could be a drawback. Im not sure if the bugs have been fixed in recent Powerchute versions. Im running B.E. v7.0.4....

Other Thoughts: I purchased mine for under $xxx delivered. I was surprised newegg
was so much more but on ocassion they just cant match certain prices but 90% of my purchases are from newegg.
