Unless aiming for extreme cooling, a 3950X using air or water should comfortably stay under the 300-watt threshold for an 8-pin setup.
This requires just one 8-pin connector, which can deliver up to 384W or more depending on the board and power supply combo. For newer Ryzen 3000 chips, you don’t need anything beyond that unless you’re pushing the 3950X to extreme overclocking conditions with a very specialized setup. You can connect the cable directly; not connecting it won’t affect performance at all.
