Pretty scummy that a pre-built sold by a company supposedly in the know would use sucha pos psu in general regardless of price, let alone sell them in general.

Then your over clock isn't stable.
Prime is running complicated mathematical calculations. A stable system would run that for days without throwing any up errors.
Some folk here would say that's ok as these calculations are extreme and not typical of standard usage. I take the view that it's the job of the CPU and memory system to calculate that 2+2=4, not 2+2=5 (bit simple but you get me point).

Did you get it sorted mate? Was gutted for you when I red this.
You're right.
After looking at the motherboard manual there are a couple of USB 2.0 connections on the board. And one of them is in use. Tracing the cable would be a headache with how well they've tied everything up, but the only thing it could be connected to is the front panel.
The difference in speed between the first 2 and the second 2 is about X10 as shown below, which is about the same difference between USB 2.0 and 3.0.

Thank you for the PSU recomendations. I asked if they could replace the PSU with a different brand rather than swap it out for the same brand / model, and I said that I would pay the difference in cost.
I mentioned the 2 PSU's that I would prefer and they said they would swap it with the silverstone one that I had picked below free of charge. Which was really nice of them.

They're coming out to collect it this week. The delay has been because of me, trying to source a box tall and wide enough to put it in, and finding a temporary PC to use whilst they're repairing mine.
Eventually I found an empty box big enough on Amazon. Shouldn't have thrown out the original packaging.
I'll make a pirate ship out of it or something with the kids because £20 for an empty box is ridiculous. But it is what it is.

That's all I have to update so far, I'll make another post once my PC comes back to me.Thank you all again for your help
So I received my computer back, this was the technicians report:
(SYSTEM REPAIR: Other (Not Listed), Component Failure, PSU was replaced due to clicking whilst under load, replaced with an alternative as requested. Tested the system. System was crashing on blender when we were running a render test. Re-installed windows and all of the drivers then re-tested the system with no further issues.)
When I booted it up, the bios had been reset to default and windows 11 had been factory reset. After installing windows 11. I installed the drivers from the motherboards website, and I reloaded the overclocked bios profile that they had saved, I ran Prime 95 and got two errors within 11 minutes. But the good news is the PSU isn't making any clicking sounds.
Prime 95 results example
worker #1
Fatal error: Rounding was 0.4975535683, expected less than 0.4
Hardware failure detected running 360K FFT size, consult stress.txt file
torture test completed 3 tests in 5 minutes 1 errors, 0 warnings.
Worker stopped
worker #5
Fatal error: Rounding was 0.4.998537884, expected less than 0.4
Hardware failure detected running 4608 FFT size, consult stress.txt file
torture test completed 12 tests in 11 minutes 1 errors, 0 warnings.
I tried again after completing all of windows updates the same issue.
I cleared the CMOS battery loaded the same saved overclocked profile. Same issue.
I ran a memory test from the bios it came back with zero errors.
The whole time I only had a keyboard, mouse, ethernet and monitor plugged into the ports.
I reset the Bios back to default, ran Prime 95 for 30 minutes and there was no errors. The CPU was running around 4.7ghz the ram defaulted to 2.4ghz instead of 3.6ghz.
I tried their overclocked profile again which changes the CPU to 4.98ghz but I left the ram at 2.4ghz, and prime 95 still came back with similar errors.
I formatted the drive installed windows 10 instead of 11, installed all the drivers and updates, same issue.
Since receiving the PC back the temperatures seem slightly higher. Its worth noting that the room is 2 degrees hotter than it usually is. As the thermostat reads 24 and its set to keep the room at 22.
Idle
CPU temp before 34 degrees now 37 degrees
CPU Package temp before 35 degrees now 40 degrees
GPU temp before 27 degrees now 27.5 degrees
Under load:
CPU temp before 78 degrees now 84 degrees
CPU Package temp before 86 degrees now 95 degrees
I'm guessing the reason the technician received no errors in prime95 after reinstalling windows and drivers, was because they had reset the bios back to default without realising. Its the only way I don't receive any. Or am I missing something?
Some websites online state the prime95 errors don't really matter unless you're rendering or gaming etc. But I render all the time which usually pushes the CPU constantly to 100% on all threads for 2 hours at a time. And I game, but nothing as intense as that. Just GTA 5 and dying light atm.
I haven't installed any games or tried to render anything at the moment. As its a headache to install it all, and figured its best to have nothing but windows installed whilst testing.
I know a comment above said that this means that their overclock isn't stable (which is something I paid them to do). Does this need fixing? What do y'all think?

They not supposed to get a stable overclock. If everything runs fine stable then leave the damn thing alone.
If you want to overclock and have it unstable that’s up to you to find the fault.
If you paid for them to get a stable over lock then ask for a part refund and just leave it alone stock.

If it cost extra for overclock
Then you would need to check any small print
Or agreement with ocuk as to what constitutes stable
What defines stable overclock to one person
May not to another
Either way only speaking to ocuk about will give you
The answer
Backing off the overclock a very small amount
Will probably make those errors go away
As for temperature they may have used slightly more voltage
This time for the overclock
Again a small decrease will probably bring temperature
Back to where it was
Personally I don't use prime95 torture test
Running stuff that you will be doing in everyday use
Is a more realistic test to me
That's the thing with overclocking
Nowadays there's very little headroom left
The old days of overclocking 50% on some chips are long gone
Plus unless you have an air con in the pc room
Come summer time you have a lot more heat to contend with
Is the extra 300mhz worth the hassle?
Does it make a big difference to your work time?
Plus if you ever update the bios
The overclocking profile will be gone
Which is why if you want an overclock
Learning to do it yourself is a better idea
That way you can adjust stuff to temperature and fan noise levels
That you are comfortable with

I wouldn't mess around with voltages and the overclock settings unless OCUK where guiding me over the phone.
I have the bios profile saved to USB and to a text file, so I dont loose it. After reloading windows 11 and using HWinfo to check the temperatures of the individual cores whilst running Prime95, I noticed the cores that where throwing the errors where the ones hitting 95 degrees.
Which is 5 degrees below the suggested limit for the processor.
But you're right real life usage would be a better gauge to whether its running correctly. I'm going to install some games and render some stuff over the next few days.
If it starts resetting, crashing or shutting down I'll give them a call. Prime95 seems to stop using the individual core that hits those high temperatures after running for 6 minutes.
Worryingly, I'm not sure if D4z will do the same. And it runs the CPU at 100% the same way but usually for a couple of hours. Which was perfectly fine before sending it back to them.
I got them to build the PC and overclock the system because I didnt want the hassle of doing it myself. But unfortunately I didnt realise that if you send your PC back to OCUK.
They won't fix any faults you dont diagnose yourself. The technician stated he didnt have any problems with a blend test after a fresh install and updating drivers, where as I am. So I'm trying to rule everything out.
Afterall, they wont fix it if I don't tell them what it is. So I'm having the hassle of having to test it. Personally if I had built it myself I'd just run it with stock settings.
But if you pay to have a system built a particular way i.e overclocked with the promise of all 8 cores running at 5ghz, 'As was advertised'. You expect to get what you paid for.
edit: As for the noise of the fans. I really don't care. Theyr're usually spinning at 100% whilst rendering and are quiet loud anyway.

I have a PC upstairs that is not Prime95 stable , it drops worker threads everythime I test it. It is however stable when gaming and my son who uses it does not complain about crashing. I do not do any professional tasks or rendering on that PC so your PC may not be stable for what you need it to do.
Crashing in prime is normaly due to memory instability although your high temps are also concerning and most likely the cause. The 11900K always runs hot but you do not want it to run at 95c on long render runs and the fact that it is running almost 10C hotter than before is either due to a poorly mounted heatsink on the cpu or the cpu is being fed more voltage than before. If I was in your situation I would reseat the cpu heatsink (with hard tubes a real pain so hope you have soft rubing) and then retest. Then update bios , downclock the cpu 100-200mhz , check the xmp profile and Vcore and Vsoc values and adjust memory timings if needed.
Unfortunately you are experiencing something I learnt a few years ago , if you want something doing right you have to do it yourself.
With that in mind you will certainly benefit from undervolting your cpu. You can do this in the bios or you can use Throttlestop - https://www.techpowerup.com/download/techpowerup-throttlestop/ . The benefit of throttlestop is that you do not need to go into the bios everytime you make a minor change and if you make a mistake then throttlestop does not enable the values until you have booted into windows so you do not need to clear cmos anywhere near as often.

Saving the bios to a text file good idea
Or photograph all the settings
As saving it as a bios profile
Is what I meant if you ever update the bios
Bios profile from one bios version to another don't work
So you wouldn't have been able to load it back into a new bios
Yeah run some of the render stuff
That you normally do
That will push it pretty hard
Not as hard as prime 95 does
Which sounds weird as they both show 100% cpu usage
But so does cinebench and its no where near as intensive
So one 100% isn't necessarily the same as another lol
Yeah if it comes to you would rather turn down the overclock a fraction
Having ocuk tell you how over the phones reasonable
Saves the downtime of returning it again
Though as I said earlier learning to do it yourself
Is also a good idea
If it hits 40c this summer a lot of us
Including us full custom loop guys alter stuff a bit
To account for all that extra ambient temperature

So, your fans spin at 100% and that noise doesn't bother you, but some cracking noise does? Got a spinning HDD in the machine?

If he's paid for a pre-oc'ed supposedly by professionals pc then he should get for, otherwise what was the point in selling/marketing it as done by professionals and stable?
When something as simple as reading a spec list of the build that would clearly state pre-oc'ed build built by us and hmmm doing what the customer paid for as a bespoke/specialist service isn't done then what part of 'specialist' is he paying for exactly? Negligence clearly...

PC Fans are supposed to make a noise when they spin. Having a PC make a crackling sound is like having a cat that barks. It's not the norm. And could possibly indicate something isn't right and needs investigating. Which is why I posted. And no, I have no spinning drives.

If he has 5 grand to spend on a pc
Fair play to him it's his money to do whatever he wants with it
While 5 grand for the pc he got
Wouldn't have been the choice of a lot of us
Since we can build our own
And do our own overclocking
And pick and choose whatever components we want
Plus part of that 5 grand includes the rtb warranty
Whereas we would have to deal with
Removing and returning individual components
If we build our own
And have an issue With something
