do you think the noise may come from psu coil or chassis/cpu fan?  seems those are the two possible noise making components in your pc?  because this is a new model, I suspect psu first. you can open the case and try to locate the source of noise.

Are you sure you do not have an SSD and an HDD?

Thanks for your reply, There's only the one drive showing in Device Manager: NVMe KXG60ZNV512G NVMe KIOXIA 512GB.  No reference to an HDD.

It might come from the speaker inside the PC or from Your monitor (if it does have a speaker)....

Thanks, but the noise is definitely coming from within the case, I am directly in front of the monitor (whose speakers are turned off anyway and the Windows sound scheme is set to 'No Sounds'

Thanks, doesn't really sound like either, I will run the machine with the case open tomorrow to try and clarify.

As you suggested I ran the machine 'with the lid off' and the 'arcing' noise is definitely coming from the PSU, which also seems to give a much quieter and less annoying 'ticking' sound with the machine powered off (but plugged in obviously).  Is this to be expected or is it a fault with the PSU?

it is somewhat expected of oem psu.  psu has many transformer and rectifier circuits inside which could make some noise.  it is not "faulty" in the sense it still works to power your pc.  it is just dell oem psu does not use high quality components.

Presumably based ion what you say Dell wouldn't replace it, or if they did it wouldn't make much difference as the replacement would have the same problem (or worse!). Are there higher quality replacements available or is it such a proprietary fitting that's not possible?

not sure Dell would replace psu just because it makes a bit noise, but otherwise functional. You can chat with Dell online.

7090 SFF psu spec Small Form Factor:
300 W typical 92% Efficient PSU, 80 Plus Platinum 200 W typical 85% Efficient PSU, 80 Plus Bronze

what is the DP/N of your psu?  If Dell cannot replace psu for you you have option to buy a Dell OEM psu made by a different manufacturer and hope by chance that would solve the chattering noise issue.  No promise.
