Hi,
I was building a new system & thankfully I got all the parts except for the UPS (Uninterruptible Power Supply) where I am a bit stuck as what to choose.

I read that there are two types of wave forms: some that output "Stepped Sine Waves" & others "Pure Sine Waves". I heard also that an incompatible UPS can damage the PSU.
The thing is that according to my calculations I may need the UPS to deliver around 300W or 400W at max, & I hope the battery backup time can let me finish/save my work for at least 10~15 mins.
One more thing: is that I would like the UPS to have an LCD screen so that I can see/know how much power/time is left.

The brands available that I can afford are:
☺ Icon 1200VA with LCD screen. (I can't find their website?)
☺ APC 650VA (no LCD screen). (APC 1000VA is way over my budget limit).
☺ BU600e 600VA. Runtime: 50W/120W Load => 34/18 mins. so I suppose 360W => 6 mins.
- there are other brands like Infosec, Emerson... but I don't know much about them.

Here is my System specifications if needed:
CPU: Intel i7-4790 3.6GHz
CPU-FAN: Cooler Master Hyper 212X
Mobo: ASUS B85M-Gamer Micro-ATX
RAM: Avexir 1600 Budget Series 8GB (x2)
PSU: EVGA Supernova 550 GS
GPU: Gigabyte GTX 950 Xtreme Gaming 2GB
CASE: Thermaltake Core V21 Black
SCREEN: BenQ CL2023

Occasionally:
I may plug-in some external HDD(s) for backups from time to time,
I may also use an external Samsung Slim DVD drive/burner when needed


So here are my questions:
☻ How to know which wave-form (true-sine-wave or stepped-sine-wave) my EVGA Supernova 550GS PSU can support?
☻ Can someone recommend me a UPS that is compatible with my PSU?

And thanks in advance for any help.

Not familar with either model.

My read is that the CP1500PFCLCD seems to be a good match for you. But the link actually shows a CP1000 model - doublecheck the model comparisons you wish to make.

For the most part the respective product reviews are positive. Just sort so you can read the more recent reviews. Look at critical reviews to see if there is some pattern developing with respect to poor quality or customer support...

Also take a look at the question/answer sections.

Found this link this forum:

Not your models (setting aside the link matter) but the tear down may provide some additional guidence.

Both models look good. Just...

Here a a link from within this forum that addresses your question.

You probably should contact EVGA and ask them the question via an email or some other format so you can document the answer. Just in case...

My other suggestion is that you remember to take all manufacturer specifications with the thought that they were created or otherwise established under ideal conditions. Or took advantage of the wording within some standard to make their product seem better or otherwise stand out. E.g., "USB 3.0 compatible" can simple mean that a USB plug fits in a USB 3.0 slot - not necessarily that it is indeed USB 3.0. Read carefully.

And do bear in mind that the more devices connected the faster the USP battery will run out. I figure the only safe margin is enough time to immediately and gracefully shut down supported devices if the power goes out.

Thanks for the reply.
But there is no-link in your post.
Can you re-post the link again. thanks.

And I already contacted EVGA and I am waiting their answer.
I was hopping to get an answer yesterday or today-morning so that I can order the UPS today to receive it tomorrow.

Thanks for the link. I'm learning a lot.

I will exclude the APC Smart series since they are too much for my actual wallet.

Can I trust that anything like this CP1500EPFCLCD or CP1500FCLCD is enough & can really output pure sinewaves for my system?

Both models look good. Just depends on how many extra features you need. I tend towards simplicity. Would not use the coax and phone line protections. And probably not the USB and serial ports either - just the front panel display.

And you need to look at the number and type of outlets. The PC1500EPFCLCD seems limited. Do you need UK sockets?

Look at the physical measurements and then at your intended UPS location. More space behind is really needed once all of the power cords, etc. are plugged in. Cable management becomes problematic. And the mini towers can be heavy and awkward to move about once everything gets connected. I have used small wheeled dollies to (like the ones sometimes used for large desktop towers) to hold UPSs up off of the floor a few inches and allow some limited movement.
