What crappy luck

WTF has happened in here?
If your psu was the Powercool X-Viper 1000w that has been mentioned then that is a very low quality psu and the best place for it is the bin. If you are lucky it has only killed itself but these cheap psu's have a tendancy to kill other components when they fail. Hopefully the new psu which is a high quality unit, will be installed and everything works. In the meantime get that garbage psu out of your pc, cables included (never ever mix psu cables) and have a good clean of the fans etc while you are waiting. Don't be tempted to keep trying that psu as you will only make things worse.

Older PSU, despite claimed or real output, struggle with new CPUs and GPUs. Most common issue, apart from natural degradation, the amperes available at the 12V rail is the culprit.
So not just about total power, but PSU project is worthy checking.
3900x + 3090 was (under benchmarks, whole system) pulling about 500W from wall. Previous EVGA G2 750W Gold was plenty. The issue was the noise of the fan when on due to mounting it sideways.

Crappy old PSU + Nuclear Reactor 3090.
That was always going to end well.

using an rm850i with a 3090, works fine.
the weirdness continues.
New PSU arrived, still the same problem but slightly better. Switch doesnt work, but now jumping the atx starts the PC??
I think the crappy psu has blown something on the mother board. MB was ordered in Spetember. Now there little choice of x299 MB's about.
Any suggestions? RMA the MB?

Might be a doggy switch if it dont work, try another switch.
Just shorting the two pins of the header would be the same effect wouldnt it.....tried that, no joy

Does it always work when you jump the power switch header on then board but not when then the power switch is connected? If so sounds like a faulty power switch.
take pastymunchers advice m8.
I have, New psu has made little difference .....
Doesn't joining the switch pins momentarily on the mb header mimic the switch? If so ive done that and no joy, so rules out the switch?
Jumping header doesn't work. I'm getting it running by jumping the cables on the atx power connector. Pin 16 power on and ground pin 15
Just to be clear, have you disconnected everything non-essential, flushed the power, pulled the CMOS battery and re-seated the CPU? If you've done all that then I would certainly be looking at the mobo as being at fault.
EDIT: Apols if you have done all the above, but I'm just going through all the steps I used to go through. If reseating the CPU does the trick then you're probably still looking at the motherboard, as I came across a few systems that acted up like that. Reseating the CPU would work for a bit, then it would fail again.

I had something like this happen and it went on for about a year till i worked out it was a problem with the main 3 pin wall socket not connecting to the pins on the plug properly and was causing all sorts of boot errors
It was something i never would have thought of checking, I changed the PSU, PSU power cable, GPU, Memory, Disconnected & removed everything possible Etc Etc, took the whole PC apart and rebuilt it about 50 times

So did you try putting the 3070 you had previously in it? That would rule out the 3090 being the issue. To be honest though it sounds like the psu gave up the ghost and took out the motherboard with it I've had that in the past with cheap psu's that literally went bang and nigh on took out the motherboard with it.
Without swapping out components its difficult to know for sure whats going on if you can beg steal or borrow spare bits to try out do so otherwise its one of those nightmare situations to deal with
