New PC build > Power issues / No apparent power >

Hi there guys, I was hoping that you could help me with a couple
of issues that I've been experiencing.
Background / History:
My old PC has died (unbeknownst to me) - It appears that the water / oil cooled
AIO had ran dry and the CPU cooked itself to death.
As a result, a good friend of mine has provided me with the parts I need to
build a new PC (whilst still using some parts from my old PC too).
For the build I have done the following -
1). I've cleaned the CPU and the heat sink with Isopropyl alcohol
2). Then re-applied new fresh thermal paste to both the CPU and the heat sink
3). Added the back plate to the motherboard
4). Connected the CPU and heat sink to the back plate (and it is now properly
secured).
5). Installed the RAM
6). Connected the cabling (power and SATA) to the various drives
Issue: Power
When I've connected all the main parts back together
I don't appear to be getting power to the motherboard / components.
However strangely when I hit the power switch (on the PSU) I can see coloured
lights from beneath the motherboard (just basic stuff)
AFAII there are no LED strip lighting on the machine, and I have never placed
any on the PC or case.
But when I hit the power button on the front of the PC - Nothing happens
The fans don't spin (either the exhaust fan or the CPU fan)
No lights / sounds are forthcoming.
There are no lights on the LED status lights on the motherboard.
I'm hoping that it's something simple and obvious that I'm missing
that's preventing my PC from powering on properly.
Troubleshooting:
1). Connected the 24 pin power connector to the motherboard
2). Connected the CPU heatsink and stock fan unit
3). Connected the power to the CPU fan
4). Added the RAM
5). Connected the power to the front panel connector (I beleive in the
correct pins in the correct order).
6). Tried power with and without DVD / SSD / GFX cards connected = No power
7). Re-seated the 24 pin ATX power connector to the motherboard a few times
(It appears to be full and firmly in place)
Question
1). What am I missing / what do I need to do, in order to get power to my PC ?
Details / Specs:
Case: Thermaltake Core V51 ATX Mid Tower Case
Motherboard: ASUS TUF X570 Plus
CPU: AMD Ryzen 5600-X
RAM: 32 GB (DDR 4)
GFX: Nvidea GeForce GT 1060 (6 GB of VRAM)
PSU: Unknown (I suspect it's a 750w - 800w unit)
TIA for any help or advice.

That just never happens. If CPU overheats, the system shuts down to save itself. Unless you deliberately disabled all safety functions in the bios.
I can't get a full picture of what you did from your post. If you are sure everything is properly connected and your power switch is correctly connected and you still get nothing that sounds like a dead PSU or dead motherboard.
When you assembled everything, did you mix cables from 2 PSUs? If you did, that might be it. You might have fried something because you must never mix cables between different PSUs. Those are not standardized.

Then why do some aio radiators have fill ports???

To fill them? I'm not saying AIO are indestructible. They can break. I am saying CPU won't cook itself to death. There are safeguards. CPU will thermal throttle, downclock and shut down before any damage happens.

08). [On the OLD PC]
The AIO was quite old (7 yrs approx) I bought (my now old PC) from another friend about 2-3 years ago
I had no idea that this AIO was water / oil cooled. So I had no idea that it may "run dry" at some point in the future.
09). [On the OLD PC] I definitely did not, remove any safeguards in relation to preventing the CPU form overheating.
Neither did I overclock my CPU.
10). [On the OLD PC]
When the CPU died, the motherboard had 2x LED status lights
1). For the motherboard = Which was green
2). For the CPU = Angry red
The PSU was providing power to the PC
The fans were still spinning. The motherboard was getting power The CPU LED was red (showing an issue with the CPU
So (to me) this indicates that the PSU still worked and can provide power properly.
11). [On the NEW PC]
I am currently still using the original PSU, with the same cabling as the old PC. (As I've effectively swapped out the motherboard / RAM / CPU but kept the original tower case, PSU, cabling).
12). I have not (yet) tried a different (known working PSU) with my new PC build.
To determine if the PSU or the motherboard is at fault.
That will be my next step.
