Question 3080ti Low Power Draw 220W

Title lists the main problem. My 3080ti Eagle is only pulling about 220watts. I can get it to 230 watts sometimes.
I reinstalled windows, reset my bios, and used different 6+2 cables and PCIE power ports on my PSU (yes I am using two different PCIE 6+2 cables and not daisy chaining one). I also forced PCIE 3 and 4 on my x16 slot. None of that fixed anything, so I'm assuming one of the 6+2 pin power connectors is broken on the board itself. Since the 75W PCIE slot +150 watt PCIE power cable = 225 watts. The gpu is running absolutely perfectly other than this power and performance issue. I went ahead and removed the GPU so it doesn't fry my motherboard, and I am running an old 2060 super now (which is running great lol). There is more story to this.

I got a used 3080ti Eagle about 3 months ago. I was playing DS3 and my computer shut off randomly (while I was about to beat the nameless king no less lmao). My computer then shut off when it was sitting around doing nothing the next day. A day after that and my computer would start but with complete black screen. I figured the used gpu croaked so I swapped it with a 2060 super. No dice. Then I swapped the cpu with a 5600x. No dice. Then I figured the motherboard or PSU must be fried. The PSU was an EVGA 750w supernova gold( I don't think it was the problem, even if I was nearing the power ceiling with the 5900x and 3080ti, i don't think the 750w would allow itself to fry the parts). The mother board was a 6-7 year old Gigabyte B450m (I think it died, with all the used high wattage overclocked cards that thing went through in the last 6-7 years I basically executed it).

I got a new motherboard (b550) and EVGA 850w G5 PSU (just in case the 750w actually died). Computer booted up and worked great with the 5600x and 2060 super. My 5900x was completely fried though. Which is wildly rare, and I knew the temps on it were average, so I know I didn't cook it. It had a brown spot between two pins, can't tell what it is exactly without some magnification gear. I'm assuming it was a short (which still, sounds insane to me, shouldn't really be possible). There just shouldn't be enough voltage for that as far as I know.
I got a new 5900x and it runs flawlessly.

My 3080ti on the other hand runs flawlessly, I thought it survived at first, except one problem, capped at 230 watts.

Thanks for reading this super long story. I happen to be and Electrical and Computer engineering senior student so I think I have a decent diagnosis. I think the motherboard died and damaged all of my components, however it is possible that the 3080ti fried the motherboard(I'm assuming a power connector went bad on the board itself and the 3080ti overdrew wattage from the motherboard, killing it.) If anyone has a tip on how to fix the card or cpu I'd be glad to hear it. Or possibly a different diagnosis would be nice, since at the moment I'm sitting here with 800 dollars of damaged parts. I don't plan on using any of the parts I fix since I need a reliable desktop for school and gaming. I don't plan on selling them either (I'm not a bastard).

I already ordered a 4070ti because I am weak and all the AMD cards I've tried have been stuttery.

OLD SETUP:
Gigabyte b450m ds3h
5900x
3080ti
2133 Kingston ram (yes I know this ram is crap)
Crucial m.2 1tb, samsung evo 1tb, PNY 2tb
750w evga supernova GT gold

NEW SETUP:
Gigabyte B550 UD AC
5900x
2060 super or 3080ti when I'm feeling risky
2133 Kingston ram (yes I am still running the same crap ram)
Crucial m.2 1tb, samsung evo 1tb, PNY 2tb
850w EVGA G5 Gold
 
Welcome to the forums, newcomer!

I got a new motherboard (b550) and EVGA 850w G5 PSU (just in case the 750w actually died).
Did you reinstall the OS after the motherboard swap?

2133 Kingston ram (yes I am still running the same crap ram)
You should look into a DDR4-3600MHz ram kit as that's what would net you more FPS in your games/system.

I reinstalled windows
Where did you source your OS from? What OS are you working with?
 
Hello thanks for the reply,

I used the same OS when I swapped the motherboard, and then realized the 3080 ti was underperforming so I did a cloud reinstall of windows 10. I am using windows 10 and the reinstall is from microsoft's cloud service.

I have already ordered new ram lol
