[SOLVED] Which UPS is good for my desktop computer (specs incl.)?

[streamlinelimited]

Hello!

What UPS do I have to use for this desktop computer?

Intel® Core™ i5-8500 CPU
Asus PRIME B360M-A MB
HyperX Fury Black 16GB 2666MHz DDR4 RAM
Western Digital Blue 1TB 7200RPM SATAIII HDD
Kingston SSDNow A400 Series 240GB SATA III SSD
Aerocool VX-650 650W 230V APFC PSU
LG 27MP68HM-P 27” LED FHD IPS Monitor
GPU 2GB to 4GB Future Upgrade

When the electricity is went off...
UPS Backup Usage: Saving my works, shutting down the computer properly.
UPS Backup Duration Usage: 1-2 minute(s).
UPS Connected Devices: LG 27MP68HM-P Monitor and Desktop Computer.

What's the best UPS VA/W to handle that computer? 1000VA, 1500VA or 2000VA

What UPS brand would you recommend? PCE, APC, Eaton, INVO or LeGrand?

1000VA should be plenty. You'll probably get an hour or more of light-usage runtime (less in a heavy gaming session, though) out of an APC Smart UPS 1000, judging by how long my home server (a power-hungry AMD-based system with multiple 15,000rpm hard drives) runs on one.

I trust APC and Eaton UPSes.

Thanks Molletts for replying to me. Just to remind you a 27" LG LED/IPS Monitor will be connected to the UPS and again the running time would be 1-2 minute(s) to save my work and shut down the computer properly only nothing else will be done on the backup UPS. Is a 1000VA UPS enough to handle up the computer specs with a monitor and power supply of the computer too? 2-4GB VGA will be installed later.

A flat-panel monitor uses next to nothing compared with the computer. My CCFL-backlit panel uses 45W; a modern LED one is more like 25W. When I used to have my server in the same room as my main PC, I had both on the 1000VA UPS, with dual CCFL monitors, and could run for about 15 minutes.

(A decent-size CRT would have needed 150-200W (and perhaps 500W of surge capacity at power-on for degaussing) but thankfully that's history. In CRT days, I just relied on the UPS software automatically shutting down the PC at the limit of battery runtime, with a blind Ctrl-S when the mains went off to ensure my work was saved.)
