When ever i play games and if mains power fails my ups goes into backup mode then my computer restarts. But while i am just browsing or doing any stuff other than gaming my computer does not restarts.
This issue started after i installed my gpu which is r9 270x.
I tried to switch the mains my self off while gaming but than also the computer restarted.
Is this issue related to power supply which is Corsair Vs 450 that this power supply cold not take the gpu loads or this is due to the some defect in my power supply only? Iam realy confused what is causing this somebody please help me i am not able to play games due to this.

12 volts and 150 ah the battery is fine.
I suspect the power supply is not able to take the load of the gpu and that is why the hold up time has got very less
or something else oh i am really confused.:??:

i was looking at 500 watts 12 volt rail amps it was 34 amps so i think my ups is the culprit will get it checked by apc engineer
