UPS shuts down my PC with continuous beep when playing games.
Knowing my needs I bought a line interactive UPS with 1200VA/720W rating assuming it to be sufficient for my use. But, every time there is a power outage, UPS shuts down my PC with continuous beep while playing games. It works fine with general usage. But with intensive tasks or games, it just shuts down with a continuous beep. It doesn’t seem to sustain heavy loads.
I checked my UPS manual to see what does a continuous beep mean and the manual says it is due to a fault and doesn’t really describe anything else. I thought my PC would hit 600W or so at peak and be able to sustain with this UPS for a short period(1-2mins) every time there is an outage. But it doesn't seem to work. Also, I use this UPS only for my CPU and nothing else. All my other peripherals like monitors, speakers and rest are connected to an other UPS which works fine.
Processor: AMD Ryzen 5 5600x(Air cooled)
Mother Board: B550M Gigabyte Aorus Pro AC
GPU: RTX 3070Ti
Ram: 2X 8GB 3200Mhz Ram
HDD’s: 1X 250GB m.2 NVme SSD, 1X 1TB 7200RPM SATA drive
PSU: Deepcool DQ750-M V2(750W)'
UPS: Zebronics: Zeb-U1225(1200VA/720W)
''I would like to know if i’m doing something wrong with the setup here. Is the UPS under spec for my PC? or is it really a faulty UPS? Is it not outputting enough power? Or is it something to do with the PSU? If so, what/how do I choose another UPS to support my PC?
I saw a couple of people using APC BR1500(1500VA/865W) UPS to support their gaming rigs. Does 1500VA/865W makes such a change compared to 1200VA/720W? Also, Zebronics UPS outputs a pure sine wave which APC doesn’t.
I’m clueless at this point. Please educate me! I’m worried about busting my new PC due to this. :(
