I have bought a system 2nd hand. The only part I added was the UPS. Its a Prolink 1200VA one. (PRO1200SFCU). It works fine when power turns off when not gaming. But when I game it always restarts when power goes out. I dont know if this is something defective about my UPS or if the UPS doesnt have enough power or the UPS transfer time is too slow. Do I have to buy a better brand? If so what is a good brand? But the person I bought this computer said he had a 900VA UPS and it worked fine while gaming (He said it was also Prolink). What should I do? I live in a 3rd world country with daily power failures so a UPS is a must.

The specs of PC are:

I7-5820K with a Cooler Master 240 AIO cooler
ASUS Strix OC 980TI
Kingston HyperX 4 x 8 GB 2666mhz
Cooler Master 750V Power Supply
Asus X99 PRO
Samsung AHCI based M.2 SSD as system drive. (Games are on a HDD)

The whole PC was from him even down to the mouse and keyboard. I knew he worked without any issue on this PC. Yes, I have tried plugging it in to different power outlets.
 
only times i've seen this happening is due to the games or other intensive software drawing more than average power and the UPS will give out.

VA(volt-ampere ) & W(wattage) are not the same thing.
you'll have to determine how much power your entire system and anything else connected draws and compare that wattage to what the UPS can provide.

but many cannot even actually provide what they state in their specs so it can be hard to determine.

The games I play are somewhat older games. Like Hitman 2016, CS GO, No Mans Sky. And I know the person I bought this PC from played most of those games and he said his UPS had no issus while gaming.

My PC has a 750W Cooler Master Bronze power suppy and actually draws about 600W and maybe 650 or 700 with GPU spikes. 1200VA is 855W calculated with 0.7 Power Factor. So I thought it should be good enough.
