So just for information...today i had a suprim 3090 in my system and looked only on the pcie slot power draw and the balancing and the suprim draws max 65 (its between 45-65 all the time)Watt from this slot and the 3 8pins are well balanced and equal. The Score in PR and timespy was only a little bit higher and Board Power draw was the same as by the Evga. I have not tried the xoc bios because i send the suprim back and stay with the Evga. It has ingame the same FPS and stays a lot cooler and the gaming bios from the suprim is a bit loud- the evga is better for me. So i hope they can sort this out by a bios balancing Update. besides that the bad dragon center slows my pc really down to the ground, very happy after uninstalling this and gone back to the FTW3 Ultra.
Edit in gaming i can overclock to the same level and with using the xoc bios on the evga ftw3 3090 ultra had hits over 470 Watts(on my card always 75-77Watt pcie Power draw with one hit to 80)
With gaming and stock bios with same results as the suprim i need only 385 Watts on Evga and the other one stays at 420...
So lets see time will tell im happy for the moment.
Best greetings
