UPS does not give backup

[TANVIR-09]

My ups does not give any backup while gaming if there is a power cut. It gives backup flawlessly when pc is under normal load but while gaming pc just shuts down during power cut. What could possibly be wrong ?

It is a power guard 1200va ups.

 

My specs are:

Ryzen 5 3600

16gb ddr4 3200

a Samsung nvme and 7200rpm hdd

RTX 2060 super

Corsair cx 650w psu.

ups don't work forever, the battery inside usually lasts for only 2 years more or less, after that they do not offer any power backup, is the unit old?

 

the list of parts, is the pc the only thing connected to the ups? do you have other things like tv, printers, stereo, speakers, anything else?

I don't see a wattage peak rating anywhere. My guess is you're drawing too much current under load for that UPS to handle. 

It is strange though, as most 1200VA UPSes I've used have a wattage of no less then 600w, which would be plenty for that system as you're probably somewhere in the 300s with that setup. 

Try cutting power to it (unplugging it's main power) with no load, then slowly add load (CPU stress test by itself, then GPU test by itself, then both) and see where it fails.

A 1200VA UPS with that system should last close to half an hour at full load if not more.

It is only about 9 days old. Pc is also new all purchased together. There is only pc and the monitor connected, nothing else.

if you unplug the ups from the wall, it turns off immediately with a alarm noise? all things turn off?

 

a 1200 watts ups should handle almost 3 pcs like the one you have for around 3 minutes, maybe more

 

then the unit is defective, rma under warranty, or declare it doa, anyway it shouldn't behave like this, so return it to get a new one that does work, depends on your seller, how it handles these situations

 

i persnaly only recommend apc or cdp ups
