From what we know to the latest information / rumors, The RTX 4090 will have a maximum consumption of 600W. The 24 voltage converters given to us by the uP9512 controller are a group of three. Memory is connected to four VRM phases.

In terms of memory, we see 12 locations for memory chips on the map. With 1 or 2GB chips, multiple configurations are possible. We have to 24GB GDDR6X On top of that RTX-4090 On a bus from 384 bit. With all A large L2 cache is 96 MB.
