Question PSU making loud sound when computer isn't turned on

[Jordan_stewart]

Hi,

I recently upgraded my graphics card to a gtx 1060 which I ensured was compatible with every aspect of my computer (especially the power supply), and now, when the computer is plugged in but not powered on, the psu makes a really loud humming/squeling sound.

The computer boots and runs fine, but this sound is really loud, and is incredibly frustrating - is this an issue with the psu?

Regards,

Jordan

Welcome to the forums my friend!

What is the make and model of the PSU?
Do you have a recording you are able to share? (something like Imgur for example can be used)

Does your PSU have an on/off switch, or is it the type that is powered all the time (OEM PC). If the latter, I suspect the PSU's transformer is on its last legs.

The model of my PSU is thermaltake tt-500nl1nh-1.

Here's a recording of the sound that comes out when the psu is plugged in, but the computer isn't turned on: Psu issue

Very low end and poor quality Thermaltake unit.

If you know a large squealing sound is coming from the PSU, I'd undoubtedly be replacing it.
Even if it wasn't making the sound, personally I'd undoubtedly be changing the PSU anyway.

On top of that, the 12V rail only gives out 348W total across both 12V rails so it's not really a 500W PSU either.

If you can, borrow a good quality unit from someone or replace the PSU anyway and see if the issue persists.
Far too often we see poor quality PSUs cause instability and like the ones here, cause damage to other components.

Appreciate the feedback - would the psu have damaged any parts of my pc when I used it witch the new gpu?

Only way to tell is by running the parts in another / new system with a fully working good quality PSU.
