I have been testing two RX 6600XTs since yesterday.
With minimal tweaking (basically only GPU 1350Mhz & MEM 2250MHz, no voltage tweaks) my result so far:
87.5W for ~ 32MHs (total card power on the wall)

Not sure why your power draw is a lot higher than mine but I am getting 64w/ea at the wall for five cards mining ETH and still tweaking for lower voltages etc.
