I have a PC of i5 6th gen processor, 8gb ram, gtx 750ti, Corsair 450w PSU. My ups stopped working and in my country, there is a lot of power outage and there is also a lot of voltage fluctuations. My PC had power failures about 20 times. It just turned off suddenly and restarted. This happens only when I play games. When I use the internet and other purpose, it works completely fine. But now, even though I keep my PC idle, then turned off and restarted. Is this because the power outage had damaged my PSU or something. Or maybe was there any voltage fluctuations in my house that made this happen. Can anyone also tell me the components that are damaged by power outage other than the harddisk. Thanks in advanced.
