Update to my rig. I suspect the motherboard is dead. I've managed to record the fault on video. The system never successfully booted.
 
Seen at around 1:46, the BSOD that flashes, is "Critical Process Died". My only diagnosis, is a failure of the PCIe sub system on the motherboard, as Windows is running perfectly fine on the same drive, but on another motherboard.
 
My "New" Personal Rig
I had taken out the CPU, Ram and Nvme boot drive, and threw it into a brand new motherboard. It booted first time without issues. No modification or repair was done to the Nvme between the video above, and the installation of the drive on my new motherboard.
 

I did recently install a second, 1200 PSU. I used only a single 24 pin extension just to power it on. 
 
I'm going to leave the system for a few days, to see how my existing hardware that I pulled out (CPU, Ram, Nvme, 2060) functions, and see if the fault replicates. I do believe the motherboard is dead, as when the fault occurs, Windows doesn't have time to log the blue screen "Critical_Process_Died". As if the Nvme drive was unplugged from its port. This is what leads me to think the PCIe sub system has failed, with an intermittent fault. 
 

 
I have noticed as well, that the ethernet port would randomly drop, and would have to manually replug the cable. This never happened on the Wifi.
 
After a few days, if no faults are present with the current hardware, then I'll have a look at RMA'ing the motherboard.

Here in Canada (Eastern Ontario) we have Time of Use rates which I believe are also available in the UK. What I’ve been doing is only running my rigs during the less expensive ToU periods using cron scripts.
 
Its nice that you have the option to procure renewables on your supply and they will actually pay you when they have excess wind production.
 
I’m writing up a Howto on ToU folding where you can also just raise and lower CPU and GPU power limits depending on the current ToU periods which I’ll post in the next couple of weeks.
 
I’m also working on updating my Linux HOWTO to use Ubuntu 20.04 LTS rather than 18.04 LTS which will be end-of-life shortly but I’ll have to wait a bit for that as I’ll have to take some of the rigs off-line for an extended period which I’d rather do after the cold season here ends.

That was how I had the PSUs interconnected as well. Just a Thermaltake 24-pin adadtor to send just the "power on" signal to the second supply.
 
Generally, if using powered PCIe extensions, it is best practice to ensure the PCIe bus power for an extension comes from the same PSU as the PCIe Power connectors on the GPU. Even then weird things can happen due to the shared ground via the PCIe extension.

The risers are electronically wired as 4x 4x 4x 4x. Meaning, each GPU has 4 CPU lanes. You can run a 3080 on gen 4 with just 4 lanes, as it provides sufficient bandwidth for daily tasks, even Folding at Home (I have not tried my 3080 on these risers).  This does require of bifurcation of the primary PCIe port, of which not all motherboards support this feature. I've always had success with MSI motherboards.

Well, my computer has developed an intermittent fault that I cannot identify.
 
The system would crash to a black screen. The CPU Ez led would be lit, and the debug code would be 00. After a minute or so, the system would boot as normal automatically. Sometimes, it would throw a BSOD, but it would be so fast, that the screen would go black as it was in a gradient to said blue screen. I've never been able to identify the error code, as windows doesn't have time to log it.
 
Other than that, it works fine. Just "fine".

 
Edit
 
I'm going to be looking for a more suitable chassis. It'll need to have space for an ATX motherboard, two power supplies, and at least 9 GPU's.
 
4 PSU's if I choose to go get some 4xxx GPU's.

A mining Case would likely be your best bet.

My system is very stable.
 

 
The 3080 LHR and the 2080s is on the chipset, via the ADT-Link NVME adapters. 3080 has 4 lanes at PCIe 4, whilst the 2080s is only getting... 2. Seriously. I'm not complaining, as it's working fine and is stable.
 
The GPU's as plugged in:
1050Ti - x1 lane (Runs the display)
3080 Palit - Chipset (M.2, Gen 4), 4 lanes
3080 Gigabyte - CPU (Gen 4), 4 lanes
2080 Super - Chipset (M.2), 2 lanes (?)
2060 - Bifurcate #1 (CPU, 4 lanes)
2060 - Bifurcate #3 (CPU, 4 lanes)
1080 - Bifurcate #4 (CPU, 4 lanes)

There is space for one more GPU, with 4 CPU lanes, and 800 watts left on the second power supply.

After the installation of the second power supply, the water pump was officially kicked out of the case.
