3080 ti ftw3 (OC to 108% Powertarget leading to 430W powerdraw per HWinfo64) with seasonic focus 750W. crashes during gaming, crashes on desktop, BSODs, rebooting, complete shut offs. whole spectrum.
 
installed a beQuiet Dark Power Pro 1200W. same crashes..
placed the OC switch of the FTW3 to STD instead of OC. no crashes any more
 
i dont think this is a PSU related thing.. 

While I can't say your old power supply never had any issues and you're not better off with the 1200W (I am thinking you are better off now), I would definitely agree that you have an unrelated issue.
 
The "normal" and "OC" bios switches on 3080 ti FTW3 basically only control the fan curve. The OC position never turns the fans off and has a slightly more aggressive fan curve. The Normal one has a silent mode if the temperatures are low enough because it shuts the fans off. One thing you can try is to re-flash the OC bios as it sounds like it is corrupted. I'm not sure if it'll fix it, but it would be worth trying. You can find the default BIOS and instructions for installing them here.

thx for the fast reply, i may be an idiot as it turned out lol
 
just double checked the connections on the Dark Power Pro 12 and got confused by the Multirail layout and the 12Pin PCI connectors it seems. i managed to connect all 3 6+2 Cables to the same rail with 40A.. reconnected everything so im now using 3 rails (40A + 40A + 35A)
 
everything runs fine by now, im currently testing it.
 
the thing with the OC switch seemed to be random

Ah. I think those have a little thing you can add that has a 3-pin connector and uses one PCIe slot on the back of the case with a switch that changes it from separate 12V rails to one single 12V rail. The way 30-series draws current spikes...I'd probably go for that lol. They call it the overclocking switch, but even without overclocking, I'd give my 3080ti every bit of juice I can afford to.

yep, its a little switch that would put it in single rail mode, i had to learn about its function through a lot of internet-research since the usermanual is only a general 1 sided sheet that fits all of their PSUs -.-
 
its working fine so far on 3 rails, i want to avoid single rail mode if possible, but if the OC couldnt run on Multirail, ill switch.. 
 
EDIT:
Quick update on the situation: Had some further crashes after replacing my 32gb ram with corsair vengeance 2x32 5600 c40 on both jdec 4800 and xmp 5600. i now have set the PSU to singlerail mode.. i have currently installed the 2x16 again i was running before on stock settings, system stable for now. will try it with the corsairs again to know if it was the PSUs Multirail again not functioning correct. But its weird... i start to think i have a faulty PSU but i have no idea how i could test that. and i dont think the corsair ram isnt compatible with my mainboard since so many similar corsair vengeance rams are on its vendor list.
