What psu are you using? Sounds like your new gpu may have drawn too much power and tripped the psu? Possibly a power spike to kill the board if it is indeed the board.

Corsair RM850X but it was literally installing the drivers after getting into windows. I can't imagine it draws over 350w which my old 3080 did when gaming.

Depends what the gpu was doing when the drivers were being installed. I've seen my gpu quickly spike to 100% before while installing drivers as the screen turns black for a moment when its being installed. This is why i keep an external monitoring system to watch voltages etc.

4090 is a good 100w over that. It may spike at boot too if the youtube million sub channels have anything to say to over 300w at boot based on not booting with only 300w input. I still like Jayz and Steve for putting out fun content.

Maybe the 4090 wasn't seated into the motherboard all the way too ? Check the PCIE slot on the motherboard for damage and the PCIE on the GPU for any damage.

A PSU that lights up the motherboard doesn't mean its not dead too and works when you do the 24pin trick as there is no real load on it then. Do you have another PSU in the house to test the system even if its a low wattage psu just to get the motherboard up with the IGPU on the cpu as a 100% test it's not the motherboard or cpu. Also try reseating the ram as maybe they got dislodged while doing the update.

It won't even attempt to spin up. Push the power button and it just does nothing.

So I just unplugged CPU power cables and used a jumper on the 24 pin that tricks PSU into spinning up and it did and radiator fans turned on. So I don't think its the PSU. FFS I'll take the CPU out and see if I can get the MB to attempt a Q-Flash, if it won't then its likely the MB is dead. What the hell could have caused that?

Hmmm you said motherboard lights is on then it should still work fine.

Try remove RTX 4090 and reinstall RTX 3080 and see if it will boot. If it boot fine then do DDU and then remove RTX 3080 and reinstall RTX 4090 and then install the last driver that worked last time and restart PC. Did it still boot with previous driver?

It won't do anything even with no GPU plugged in

99% it was seated correctly. It clicked in place and I had video until about halfway through the install when the screen went black and it shut down.

I've ordered a 1000w Corsair and a MSI Z490 Pro from the jungle that both arrive tomorrow.
 
Let the geforce experience do auto oc and it landed on +109/+200. Basically translates to a solid 2910-2925mhz while in game every game even with MSI suprim X quiet bios fan curve. Absolute madness.

4x dedicated. Though each of them have an unused daisy chain so it looks terrible until I get a new cable lol.

It does indeed look terrible. Wish they'd given a longer cable at least.

That lead me looking up whether or not daisy chaining would be ok. It seems like it should be fine with a decent PSU.

Are you guys using 4x dedicated PCIe cables from the PSU or 2x cables with daisy chain?

4 and end up with a mess like in my pic :rolleyes: , cant wait for the cable mod one to turn up as this really is a terrible design , oh and please excuse my ironing board cover as just bought a 4090 and times are hard :cry:
