Noise from power supply is being heard.
Noise from power supply is being heard.
Hello! After adjusting the PC's voltage a few hours ago, I began noticing this buzzing sound coming from it. It occurred while I was gaming and was quite loud and persistent, causing me concern. There were no other unusual signs such as sparks or performance problems. This PSU is new—a CX550M I purchased last year. My previous PSU was also relatively new but more affordable. I have some photos of the PSU and its ATX connector. I’m wondering if this suggests it should be replaced again.
Refresh your update with complete details about the system hardware and operating system. List the disk drive specifications—make, model, capacity, and current usage. Confirm whether the sound originated from the power supply unit. Check if you have resumed undervolting the PC; did the noise cease?
Full system specs are:
AMD Ryzen 3200g (on stock cooler)
Palit GTX 1650 Dual
MSI a320m Gaming Pro
Seaggate Barracuda 1TB HDD 6 Gb/s 7200 RPM (ST1000DM010-2EP102) - Around 65% full
Western Digital WD Green WDS4802G0B 480 GB SSD M.2 2280 - Around 71% full
CX550M 80+ Bronze
Coolermaster Sickleflow 120 ARGB Case Fan (x1).

I'm around 70% sure that the noise was coming from the PSU. This was the same problem I had with my older Cougar VTX power supply, and swapping it out solved the problem for a bit. It came back maybe a few months after, but I didn't worry about it because it rarely happened. I haven't stopped undervolting the CPU, but after plugging back in my power connectors and changing where my PSU is plugged from a wall socket to a 250v/2500w extension cord, the noise stopped.
I guess this is also a good time to note that when booting up the PC, there's also this other noise that sounds like it's "revving" in an electrical way, which also comes from the same place where the arcing/buzzing/electrical noise was coming from. This started long before any PSU problems, and happened when the PC was relatively new (around like maybe 5 months old?) after I opened it up for the first time to do a cmos reset. During that, one of my fingers brushed along the backside of my MOBO on some of the metal bits, and I suspect that might be the cause? This, I'm not entirely sure on.
By the way, thanks for the reply! I had a previous post regarding power surges and the reason for that was this very same sound. I didn't get to reply on that thread because I honestly forgot about it during a time where I was pretty busy and wasn't really paying attention to the sounds my PC was making.
After about 5 to 6 hours of operation, the sound returned, though a bit louder and less often. After checking other threads and forums, I chose to stop using the 3-to-2 prong adapter since I realized I could connect it directly to my extension cord (which was surprising me). I plan to try it again after an hour or two to see if things improve.
Using a 3-to-2 adapter is frequently necessary, though sometimes unavoidable. It shouldn’t be considered a permanent fix. Similar issues arise with power strips and discount bin surge protectors, as well as low-quality extension cords. Choosing to remove the adapter was a sensible choice. Three-prong devices or cables ensure correct grounding for safety.

As noted, thank you! To date, the sounds haven't returned yet. I'm hoping they never will!
