Hi tsanko,
after a week with the new Ventura system I finally got power managenment perfect working.
As I got a i9-10850K and a RX Vega 56, the power management with your Ventura Efi was working really badly, 100-150 watt power draw, always increasing.
Now the system with four SSD (10TB) consumes about 66 Watt in idle, very good. Very fast set back and reactions of prozessor speed, perfectly. In the end i don´t know the crucial factor, I really tried a lot. Ended as iMac20,2.
Most important: The system is still rock solid and stable. No boot failures, no crashes, Internet (via Ethernet) always working.
All changes I made (not all are power management related):

SSDT-TB4HP.aml not enabled
SSDT-BRG.aml not enabled
