Do 1Kva UPS good for 750 W PSU

[jai360]

Ok guys im looking to buy APC 1 Kva UPS and my PSU is Coolermaster 750W
does the UPS Power capacity suits the PSU ?

im looking to buy this one LINK

heres my config

AMD FX 8350
Asus strix r9285 GPU
Cooler Master 750 w PSU
Corsair 8 GB DDR3
Seagate 1TB Sata Drive
Cooler master Hyper 212X CPU
cooler master k380 cabinet
Dell 21.5 inch monitor S2240L

Do note that i got heavy fluctuation and frequent power shutdown problem in my area

so 1Kva UPS is good enough for 750W PSU ????

It depends on the UPS and how much power your PC actually pulls from the outlet: many 1kVA UPS can only output 600W or so, which means you need to check specifications for the specific unit you are considering.

You may also want to pay attention to how much battery backup time the UPS is able to provide at your typical worst-case load level since many of the smaller 1kVA units will only be able to provide 500-600W for 2-3 minutes, which is not a whole lot of time to gracefully quit a game.

All i need is hardly 2 minutes to save the Document im working and shutdown the PC safely im not worried about backup time just 2 minutes is more than enough for me

Im a designer mostly is use Photoshop / After effects / premier and cinema 4d so all i need is a UPS to save the working file and shutdown it

Do do you think 1 kva ups will be enough are its risky ???? will it take care of fluctuations ?

Are these kind of power outages really THAT common for you? I mean, clearly only you know the conditions that you're working with but if 5 minute auto saves aren't cutting it (and IIRC most pro-level stuff can be set to autosave after every input) then I'd be thinking of talking to the power company, not investing in an expensive and very specific piece of equipment.

Im from india here power supply is not stable so as a user we have to be careful when comes to taking care of electronic device so only option i got is getting a UPS that is enough to handle the fluctuations and give me few mins backup time to save my document THAT IT !!

1kVA/600W might be shaving it close if an outage hits in the middle of processing something with the CPU+GPU working on it.

Since you will be depending on that UPS for work, I would recommend spending a little more than the bare minimum to go up one VA and backup time notch above your minimum requirements to avoid having to buy another one because you slightly under-estimated your requirements a few months down the road.

Personally, I prefer spending $30 more to go up one UPS size above what I needed than discovering that I made a $150 mistake by going too low.

but i can't spend much more than this infact APC BR1000 exceeds my budget ....

How about APC BR1500 UPS this one

it got 865W output ???

does it look safe enough for 750w PSU ?

The power supply's maximum output rating is of no importance. What matters is how much power the power supply actually pulls from the outlet under worst-case load conditions for your PC. You also need to factor in anything else you might plug in the battery backup outlets, like external HDDs and LCDs.

Your PC itself might draw around 500W and at 80% efficiency, that would translate to 600W pulled from the wall under worst-case load. Add 50W for the LCD and other accessories, that's 650W as a bare minimum starting point. Add a 20% safety margin on top of that, that makes it 775W.

So 865W with the BR1500 should be fine.
