Question It could be a normal sound? (Corsair CV550)

[Blomkvist]

Hi, english is not my first lenguage so be patient please 😅:
I recently solicited the RMA for a CV550 because it started to make a really awful noise after some years (that a clean up couldn't solve). Support ended up sending a replacement unit, although upon installing it I noticed a strange noise (different than before) like something was being "dragged".

I initially suspected the HDD, so I opened the case and heard another and more worrying "electrical" sound in the space beetwen the fan, the CPU cooler and the GPU. It's also where the PSU's CPU cable is connected to the motherboard.
It isn't instantanely, as it begins to sound after powering up the PC for a couple seconds.

Thing is, I narrowed it down to the PSU because it makes both sounds even with all other components being disconnected (besides the CPU cable). And these particular noises (specially the electrical one) didn't happened before.
Could it be the infamous "Coil Whine"?

My specs:
•MB Gigabyte AB350M-DS3H AM4'
•AMD Ryzen 5 3600
•CPU Cooler ID-Cooling SE-214
•ID Cooling XF-12025-SD
•2 Kingston HyperX 8GB DDR4
•HDD W.D. 1TB Blue
•SDD Gygabite NVMe M.2 2280 225GB
•GTX1660 Super 6GB

Welcome to the forums, newcomer!

There's only so much you can convey using text that you need to use other forms of media to illustrate what you're experiencing/seeing/hearing. Might want to include an audio clip with video of the issue you speak of.

Just an FYI, I wouldn't use a CV unit in that build, something higher in quality, although the wattage of the unit is correct.

Can you inspect the unit for anything that might be impeding the fan blades movement? As for your build, can you relocate to another wall outlet and see if the noise goes away?

Thanks for the welcome!
A friend of mine said so too, but I ended up with this PSU because the economy of my country it's pretty bad (I'm from Argentina). So it was the best I could afford at the moment, I'm regretting it tbh lol.

The blades seems to be in very good condition and nothing is touching them while working. I also tried to connect the PC in three different rooms, but the electrical noise doesn't go away.

This one is coming directly from the PSU (without anything connected):
