Strange power supply problem

[wixerzp]

I have been using my PC for almost 2 years and everything was fine until it all started when I was playing the new Doom game. When I was about to punch a demon in the face, my PC just shut off out of nowhere and I couldn't turn it back on again. Pressing the power button did nothing. At first I tried putting my PSU into an older PC I have and it didn't work, but I probably messed up the connections or something. Then I put my PSU back into my main PC. Later I did the paperclip method on the PSU and suprisingly, the fan was spinning. I pressed the power button - and it booted! Everything was working fine until I booted up a game and it shut off, it wouldn't boot when I pressed the power button again. I did the paperclip method again and I was able to turn on the PC. I realised that whenever I booted up game, my PC would shut down. Then I did some testing, and found out that CPU and GPU are not the problem, because their temps are fine. While testing the games eventually the PC started shutting off and turning on itself, without me doing the paperclip method. What do I do? Also, when I got the PC, I had power supply problems and changed my power supply three times in a month. After that time I never had PSU problems until now.

What power supply do you have right now? (Brand and model, not just advertised power rating.)

It's a Modecom Feel 1 600ATX.

Replace it. Pray it hasn't damaged other components. Get something reputable and has some quality to it.

A off brand psu is likely the culprit.

The paperclip test is essentially worthless.
If your ps fails the paperclip test, you can be certain the psu is bad.
But, if it passes, it is no indication of proper psu operation.
Over time, a cheap psu can deteriorate and not deliver advertised power.
Worse, if it should fail under load, it can damage other parts.

It is time to replace your psu with something like a tier 1 or 2 unit from a list such as this:

The power you need is determined by your graphics card.

I have no problem overprovisioning a PSU a bit. Say 20%.
It will run cooler, quieter, and more efficiently in the middle third of it's range.
A PSU will only use the wattage demanded of it, regardless of it's max capability.
