Best UPS?

[Kloudkicker]

What kind of UPS should I get for two monitors, and a 1000W PC?

What's your actual wattage draw?

Between the ranges of 500W-800W. It's a test bed so the actual draw varies.

Well, if I'm talking about best UPS models that I have experience with, either APC or CyberPower, pure sine wave only.  Belkin is kind of ok for budget.  Maximize run time and get a 1300 VA+ model.  I use the 1500VA CyberPower pure sine wave model right now, it's been solid and unobtrusive.  I'd guess I'm drawing about 600W right now.

Cyberpower 1500 PFC LCD?

It's pure sine wave, very efficient, very quiet.

If you want bang for the buck, the Cyberpower 1500 PFC LCD is quite hard to beat.

 

If you want to pay a bit more, check out Eaton's 5P UPS unit.

 

As for me personally, I have a Eaton 9130 Double Online Conversion 2000VA / 1800W UPS, but I think that's a bit overkill for you. Heck it's already overkill for me, but I like it.

+1, I believe thats the one I have (or quite similar) runs bot the GTX970, 4790K and dual monitors no problem

There are the two go to units I always recommend:

That second one isn't sine wave though, I've heard that's needed for any modern PSU

Not necessarily it's idle for efficiency and in terms of compatibility, I run the APC units that have the stepped approximated waveforms without issue. All that I've encountered is some excess electrical noise from the PSU correcting for it.

Interesting.  Perhaps your PSU is better than some though, I've definitely heard that some will just reject it and shut themselves off which of course would make the UPS useless

Yeah that can happen sometimes it's a bit of a hit and miss, there have been some out there that have done testing and documentation on different units but nothing that has a good database of information.

Well with that in mind, wouldn't it make sense to just always get a sine wave one then, if there's no guarantee a step-wave will work and no documentation to give you a hint one way or the other before hand?

It's not super common situation that most run across, the stepped approximated sinewave is better in terms of compatibility than a regular stepped or square wave. Only time I've really seen a case of the PSU directly rejecting it was the use of a square wave type inverter when they replaced their old PSU.

oh, I always imagined it more like this  

 

Hard to imagine anything would have an issue with the red line one though

Depends on the unit most APC units round off the corners of it fairly heavily so it's a middle ground between the modified type ones below and sinewave, that stepped one would be in an ideal situation. It still would be best to get a pure sinewave though for as said efficiency and guaranteed compatibility.

i dont know much about electrical. whats the best, but reasonable ups i should get. 300-400 watts from my pc and a 3d printer, which will run ~120-150 watts. so probably a total of ~600 watts to be on the safe side. 

 

like out of this example, which would be the best? https://www.newegg.com/Product/Product.aspx?item=N82E16842301547 

Va/watts/joules. 

 

the 1500va/865 but has less joules than then 1500va/900 watts, but the 1000va/600 watts has more joules
