Just bought the ASUS 4090 TUF videocard. Based on the research I've done, an 850 watt power supply should be sufficient but I wanted to double check.
 
I agree with DSzymborski, not all 850W PSUs are created equal.

Having said that, if it's (at least) an 80+Gold-Certified model from a well-known name like EVGA, Corsair, Seasonic, Silverstone, Antec, Be Quiet!, Thermaltake or Cooler Master then you're probably fine.

If it's some cheap off-brand, then I wouldn't recommend trusting it.

I personally wouldn't and didn't go with anything less than 1000W with a 4090 that is paired with any high end CPU.
