My pc seems to work fine for most of the day but after it being on for a while usually 5-6 hours, it shuts down abruptly when playing games, then it starts again without any input which only happened during power outage before. When the pc starts again it gives me a power surge warning. it doesn't do that when I'm not gaming and before I could still play games as long as it wasn't that specific one. the problem went away for a month but now it's back again except it shuts down no matter what I play. I don't have any other PSU's to test it but I don't want to buy a new one without fully knowing whether it's actually the PSU
