Hi again, bad news

I tried to replace my graphic card, with a brand new card. But, as soon as I plug in the new card and tried to run a game. I got the same problem as before.

Corsair RM850X V2 White 850W

I think it unlikely to be the cause but at this stage anything - more or less is worth trying
Have you connected both the 8pin and the 6pin power to the card, the power draw is 256 watt on heavy demand and 231 on med gaming
You will not get that 256 from the 75w of the slot and the 150 on the 8 pin
you need the 6 pin as well

I am confused "Gigabyte GeForce RTX 3060 Ti GAMING OC 8G LHR" only has a single 8-pin connector.
