Hello,

I recently swapped my old power supply for a new one. Since then, my computer will shut off randomly and then turn itself back on.

Sometimes it will be working for hours and then randomly turn off, with no other issues for the day. Other times it will shut off after maybe 1 hour of use, but throughout the next few hours it will randomly shut off, sometimes multiple times within the hour.

When I installed the power supply, I tested the computer out doing some VR for an hour. The next day working from home, I experienced the issues. The following day I only experienced one computer shut down. I live in southern california and we did have extreme fires very close to where I live. During the fires the lights in the apartment flickered. However, the shut downs did not occur during any flickering. Today there has not been any flickering issues with the lights, but I did get the one random shut down.

I had a 500w power supply and upgraded to a Corsair 750w to be ready for a new graphics card. I am not sure if the fires and heavy winds are affecting power in my area and maybe my computer is shutting off because my apartment is getting random moments of decreased power, or if maybe my power supply is defecitve.

What are the troubleshooting steps I should take?

If brownouts are common in your area, I'd suggest looking at getting a UPS (uninterruptable power supply) to protect your system.

I checked all plugs were in tight. I swapped out the new faulty PSU for my old one. So far, no problems. Thinking its defective. exchanging for a new one to see. If I have problems with power with my old one, then its the electricity in the area due to the fires. Thanks guys!
