ups for 1000w smps

[pradeep007]

is 1kv UPS enough for 1000w smps for pc.What are companies and models for this specification

The wattage of the PSU is not what you want to look at, rather the wattage the PC uses (which won't be 1000W). What are your build specs? Also, somewhat important, what PSU make and model?
Currently, APC and CyberPower are the primary players in the consumer UPS realm

I'm going to recommend the APC BI850SINE-IN UPS which features Pure Sine Wave (important, I'll explain below) and supplies 850VA and up to 500W (yes, 500W will power your PC but not much more). One possible drawback is that it only has one outlet

The reason that a Pure Sine Wave UPS is desired here is that your PSU features Active PFC. Active PFC PSU's may not play nicely with UPS's that supply a simulated or stepped sine wave (it depends on the design but it gets very "iffy"). If you decide to consider a different UPS that does not specifically say Pure Sine Wave output (such as the APC BR1000G-IN Back UPS Pro which shows Stepped Approximation to a Sine Wave may work) or show that it is compatible with PSU's featuring Active PFC, I'd suggest contacting the manufacturer to ensure proper operation before purchasing. I've found they are usually good about responding and suggesting an appropriate model for your needs
If I'm leaving you with questions (I imagine I may), ask and I'll try to explain better

You said 850 VA for the APC, but my SMPS is 1000w. How would this act as a perfect match for my pc. Could you please explain. Thanks.

The maximum wattage your PSU can provide has little to no bearing on the system's power draw, that is determined by hardware. On top of that, the VA rating doesn't directly relate to wattage, it relates to run-time on battery. The configuration you have, i7-4790k/GTX980Ti will draw a maximum of around 375W without overclocking and up to 450W with overclocks. Your PSU, being 90% efficient would need ~495W from the wall (UPS) to provide the hardware inside with 450W. Since the... oh dear, I just realized something I hadn't checked, the BI850SINE-IN does not feature automatic shutdown software (APC's PowerChute software) and that would be wanted (especially if the monitor is not powered by the UPS also) so we'll need to take a different tack here and look at the BR1000G-IN again since it does have the ability to shut the PC down properly by itself
I'll continue my earlier thought here... since the (now) BR1000G can provide up to 600W, you have some headroom for other low power components (possibly a monitor even - that wasn't a thought with the other UPS) but the more you add to the UPS (up to 600W draw), the shorter the run time on battery.
Here's what I'll recommend doing, contact APC ( http://www.apc.com/shop/in/en/products/APC-Power-Saving-Back-UPS-Pro-1000-with-LCD-230V-India/P-BR1000G-IN )to clarify the the BR1000G-IN will work with the CoolerMaster V-1000's Active PFC.
Once you have that information, please let us know what they say so we can use it for future recommendations (especially if it does work)
Once again, if I'm confusing you at all or if something just isn't clear, ask questions
