High Pitched whirring of PSU (not constant)

[Breadsticks]

For like the past 2 weeks i have had the worst time with this PC which is surprising because some time ago (roughly 7-8 months) The power cable for this PC literally melted itself onto the prongs in the back! I have since replaced the cable and no issues arrived after that except for some crashes here and there.

The PC 2 weeks ago has started making this high pitched noise that i legit can not find an example of. I've looked at coil whine videos thinking it would be that. However the fact is that if it was coil whine it'd be the GPU but the sound is NOT most prominent at the inside of the PC but rather at the back where the PSU is. I've cleaned the PC, I've done driver updates but the sound is still there. 

Some clarifications real quick: The PC Runs fine and I'm able to stream on it fairly normally still. The issue comes at the noise going through my microphone which is why I need the sound gone. The Noise also is NOT constant. It also is NOT only when playing games that take a lot of resources to run, in fact it seems "almost" random. Sometimes happening when doing absolutely nothing and sometimes when I just start to open a tab on a browser. It doesn't quite sound like coil whine either it is more "buzzy" rather than hearing actual fans make its sound. Granted when the noise isn't there the pc runs fine and almost as if there's never been an issue at all.

Sorry for the block of text but I don't quite know how to ask for more help, Is it smarter for me to get a new PSU? And should I upgrade it while I'm at it (after all I looked into the Wattage needed for my specs and it seems 800W is kind of on the lower end anyways)? Or should I just completely switch over to a "Build it yourself"?

Welcome to the HP Forum.

You should probably replace the power supply.

I think I would have replaced the power supply right after the PSU power cable melted.

The sounds could be a failing fan or something else is happening.

Power supply failure can sometimes take down every connected component when it dies.

Thanks for the help, however I'd like to ask one more thing. When i search for the PSU i have specifically I can't find it in the "product search". I don't know why that is.

And when it comes to replacing my PSU should i replace it with a better one? This one is 800W which as far as I am aware is roughly enough to keep the system running but you should have wiggle room for a bit more right? Should i go with a 1000W?

And if i do take a 1000W PSU what PSU should i take exactly? And does it have to be a HP PSU?

Kind regards.

My pleasure.

Your PC's: case and MB can do any standard ATX power supply having similar dimensions to the currently installed HP power supply.

You could do a 1000 watt power supply if you want to provided it's dimensions match or are very close to the HP PSU.

I don't think you need 1000 watts but it's better to have more available power vs not enough power.

Make sure you get a newer ATX 3.0 or ATX 3.1 power supply ( the ATX 3.1 PSU would be preferred). The newer PSUs support the Nvidia 16 pin power connector at the PSU and the graphics card.

Component selection is subjective.

I have been using: Corsair, Seasonic, and Asus power supplies over the years having no complaints.

I actually have one last question. How do i figure out my dimensions for my PSU? Do i need to measure the PSU myself? Because i've tried looking around and seeing dimensions for PSUs seems generally fairly hard? I don't really know if people have had this issue before but I can't find out which PSUs to get because of it.

Still very thanks for the help it's been great!

The best method to get the HP power supply dimensions would be to measure the PSU.

Standard ATX power supply dimensions are: 150 mm width, 86 mm height, and typically 140 mm depth. Or 5.9 inches, 3.9 inches, 5.5 inches respectively.

Many of the newer ATX power supplies are smaller when compared to the standard ATX PSU dimensions per above. A slightly smaller ATX (only) PSU would also be good in your HP case. A SFF power supply may not work with your PC's case.
