My computer setup made a loud sound when plugged in, but I’m unsure if it’s the speaker, monitor, or power supply unit since it doesn’t happen often. With an EVGA PSU, I need to figure out what’s causing this noise. If it works fine when turned off and everything functions normally afterward, it might be something else. I should check the connections, test the power supply, and see if the issue persists under different conditions.
Ensure all speakers are switched off prior to powering on the PC, so you can verify they’re not the source.
I changed it each time but kept making noise, so I unplugged it.
However, my old 500 Watt antec and 850 Watt gamemax don’t pick up that signal
In theory, you can reduce that spark using certain variable resistors close to the capacitors. However, based on experience, many makers avoid them to cut costs and because it doesn’t usually create an issue—just some noise when plugging in, which most people rarely notice.
It's usually not mentioned in the UK since most outlets have switches. Plugging everything in and turning the outlet switch on makes it work faster, unless the outlets themselves have very loose connections. It seems the surge protection and power factor correction might be responsible, as the rest of the AC side stays off until you activate the switch. I get surprised every time I connect a live cable to the back of a PSU—it always produces that spark.
