Hi everyone! Yesterday, there was a major voltage spike in my area due to a local transformer issue, and instead of the usual 210V, we experienced about 440V. This caused some smoke to come from my PC's power supply unit (PSU) and I heard a mild popping sound, even though my PC was turned off at the time but still plugged in (and I don't have a UPS). Once the voltage issue was resolved, I tried to turn my PC back on. It powers up, but I only get a black screen on the monitor. I assumed the PSU was dead because of the smoke, but it's still on. I'm worried that one of the components might have failed, but I can't figure out which one. Any advice on how to troubleshoot or pinpoint the problem? Thanks in advance! 😊

It sounds like your PSU definitely took a hit, but just because it powers on doesn't mean it’s still okay. Start by replacing the PSU first to see if that resolves your issues. By the way, it seems like this voltage spike may have affected other devices in your neighborhood too, so you might want to look into compensation from your utility.
I have a 550W 80+ bronze PSU. Is that decent? I'm thinking of borrowing my friend's PSU to test my components. The fans on my CPU and graphics card are running, and the lights are on, so does that mean they’re likely okay?
