Have you experienced around four power supply unit failures recently, and could there be an issue with your actions?
Have you experienced around four power supply unit failures recently, and could there be an issue with your actions?
The PSU model is an MSI MAG A850GL PCIE5, and I've received these as replacements under warranty, one after another from MSI's official service center, all still in new packaging. My computer was plugged into an extension cord with surge protection. It emitted a loud pop suddenly and then shut down, which has happened before; it triggered the circuit breaker for the room but didn't blow any fuses on the cables.
My home hasn't had any power surges previously. Is there a problem with my PC parts that might be causing these PSU failures? The issues start from a week of use and continue over months, so I'm trying to determine the root cause before purchasing another PSU.
I'm not quite sure how to identify between the primary/secondary side since I can't really get a good view of the damage and I don't want to open the PSU up since that voids warranty...
From what I've seen so far though there's usually a flash of light on the side where the power cable is plugged in, and previously I've seen some damage on that side too. Is that the primary side? If it has to do with the house grid, are the ways for me to better protect my PC?
Yes, it is considered normal. The reading of approximately 50 ohms between the live and neutral terminals on the AC supply side of the PSU falls within typical ranges.
Verify that your outlet is properly grounded and the polarity is accurate.
A basic $10 tester should suffice for this task.

An appropriate UPS can address certain power problems.
