6x 3060 Ti rig draws about 850-900W on eth
1000W should be enough but I would go for atleast 1200W
I try to adhere to the opinion that if the power of the power supply unit is 1000 watts, then the real power consumption of the farm should be no more than 900 watts. This solves the problem of the efficiency of the power supply in case of overheating (in summer or when ventilation is turned off).
My friend always says, "what are you paying for?"
If you pay for 1000 watts, then use 1000 watts. The block must match its characteristics.
This should be understood as a joke, but every joke has its own clever thought.
