[SOLVED] PSU Beeping

[SpoopyWinter]

Yesterday morning, my power went out for the day. When I tried to power on my computer and use it this morning, it booted just fine, I logged in, and it had saved everything I had been doing before my power went out. The only difference was that there was a burning smell coming from my PSU. I shut it down, and let it sit for a few minutes, and the smell went away. I booted it up again just fine, no burning, but it smells weird. I shut it down and walked away for a bit. When I came back, I noticed this beeping sound that would repeat every 2 seconds or so. It seems to be coming from my PSU but I'm not 100% sure. Do I have to replace the PSU? Any way to fix it or make sure it's actually my PSU beeping?

Thank you in advance for any help or advice you can give me.

PSU - Thermaltake Smart Series 80+ 500W

Several significant issues here.

There's not really anything inside a PSU to beep, so you'd have to track this down more specifically (since none of us are in your house) if we're talking about an actual beep.

The fact that you continued using a PSU after a burning smell is extremely concerning. A PSU should never have a burning smell and once you have this, the PSU is done unless you're a professional or highly trained amateur who can take apart a PSU, examine the components bit-by-bit, and have specialized equipment to evaluate its function.

The only real option is to replace the PSU completely. The good news that even if this PSU was working properly, you really should be doing this anyway unless you have an extremely entry-level rig; this is a very low quality power supply. Then you can test and see if there's any damage done to the rest of your components.

At this point, a beep shouldn't be your concern; your components being destroyed by a failing PSU or your house catching on fire is. Worry about any remaining beeping once you resolve your extremely dangerous scenario.
