The best place to start is with a full list of specs. Hard to diagnose "mystery PC."

usually that "pop" sound has always been the power supply going out.
what make & model was it?

I notice there is a deleted post with some different components. Were these previous parts? Or is this a new build from scratch? We should be guessing about the source of your problem, not having to guess about the basic facts in your situation!

this Corsair power supply is the one that blew,
a new replacement,
or just some substitute?

Sorry no I copied the wrong component list I added the be quiet shadow rock 3 because the CPU fan was too noisy when PC was working harder.

So these were all new parts?

Yes they were

Unplug everything, put the PC case over a table and gently "stick"your nose where the PSU mesh is at the bottom back.

What does it smell like ?

Although Corsair CXM is a decent quality unit not know for its failure rate, there can always be exceptions or pure bad luck. At this juncture you will need a spare PSU to test with. Since you have built this rig from scratch as we know it from your previous thread, it would be better for you to acquire a spare unit or take it to a store for testing. All your parts are under warranty, so it should not be an issue replacing any.

partslist used is the one from, @Hellfire13 post 18.

My suggestion for new thread because it will generate more people's interest.

Think likely psu as well. Just unlucky with this one.

Doesn't really have a smell if anything like a machine

I see, it does not change the fact that a new PSU (or test unit you can borrow) is a place to start.

The pop-sound you heard, came from the PC itself or was from the speakers/headphone?

What about the power outlet from the wall, Does it look ok ?

Please be very carefull when inspecting all this things, secutiry first!!! If you don't feel confortable doing this stuff, better to call a technician to take care of the issue.

 

[VictaB]

It was plugged into a UPS

Does nothing if the fault is in the psu itself.

My son was using the computer and he had headphones on so not sure where the noise came from.
It is only a few days old should I put in for warranty?

Would do that. Otherwise do you have to test it yourself if only to see if the fan of the psu will spin.

How do I test it myself please?

 

[Vic 40]

By wiring up the green and a black connector,

In the ATX specs here can you see where the green and black are if the cables area all black,

ATX -specs/ Wikipedia, the free encyclopedia

When inserting the Paperclip, use the PS_ON+any COM, use the retaining clip for which side and what nr from the top the PS_ON is.

I disconnected the cables from the motherboard and then plugged it in and powered up but there was nothing the fans in the PSU didn't start up.

As Vic 40 wrote I would just run the warranty.

 

[VictaB]

Ok thanks

Very likely psu, as said rma is the best option (warranty).

 

[JohnBonhamsGhost]

Ok thanks

it's always possible that while inspecting, diagnosing, or troubleshooting hardware that the manufacturer could say the owner actually caused damage to the hardware and deny any warranty claim.

you would want to file for RMA before going any further.
