How much power does my UPS need???

[Miks]

Since i was using a cyberpower 650 VA ups until now, i was wondering if it will still be enough after upgrading:

CPU: i5 4670 3.40 GHz (with arctic cooling aftermarket cooler)
Ram: 8 Gb --- Upgrading to 16
Graphics: XFX R7950 DD 3Gb --- Upgrading to Gigabyte GTX 1060 G1 6GB
PSU: Corsair CX500 Bronze edition --- Upgrading to Antec EDG 650, 80+ gold
Motherboard: Asrock B85m pro4
Case: Cooler Master N600
Windows 10 64 bit
Mouse: Coolermaster CMstorm
Keyboard: Coolermaster CMstorm
Headset: Sharkoon Shark zone
6 Coolermaster LED 120mm fans
1 toshiba 1TB Hdd
1 kingston 128 GB SSD
My monitor is currently not connected on the UPS due to different ports :/

Some calculators online say it is already not enough and they suggest some 750 VA models but it worked fine until now so im not sure :/

Best bet is to get a Kill-O-Meter and see what your system actually pulls power-wise from the wall.

If you never intend to run the hardware on full loads while it runs off a UPS, then really shouldn't need much. As the idea behind a UPS is should you lose full power in your residence/office; that the UPS kicks in and gives you enough time to save your work (like say you were working on some files) and then do a proper shutdown of the PC. UPS are not meant to keep the PC running under full loads for extended periods.

You want at least one monitor on the UPS as well; so should you lose power you can still see what the PC is doing, etc.

the battery life isnt really important to me as I use a ups only so it can save my pc when the power gose out for one second( that happens in my small medieval town once or twice a week :P ) an then it comes back instantly so the monitor isnt really important, it is just so the pc doesnt shut down. But can a 650 VA ups output enough power for this build???

or can the ups output as much power as i need, like a power strip?

I'd suggest the models that are 750VA+ to ensure that you are covered. As you could have the system under full loads when the power flickers or otherwise goes out, and if the UPS is not enough, that wouldn't be good.

650VA is only good enough for approx 265-300 watts (max actual power from wall)
Now given your specs, I'm fairly sure that even under full loads, I doubt you are pulling upwards of 300-350 watts. But given the small difference in pricing between a UPS of 650 vs 750; best bet is get the 750. It is a good idea to have and do some tests with a Kill-O-Watt Meter as well; so that whatever you would want to have your UPS run, you can test those on the KOW Meter and see what they actually would draw from the wall. When you test a PC though, it helps to then run stress-tests on the PC (that will stress both CPU & GPU at the same time) so you can better judge what actual power it draws from the wall.

Thank you very much :)

Might be good idea to setup your Power Options in your OS; so that the Power Button is setup for "Shutdown" ~ Just in case you really need to shutdown the PC in a hurry, simply pressing (don't hold it in) the power button on your Case should then result in the PC going through the proper OS Shutdown process.
