Minimum Power Supply for 3000/4000 series GPU?

[stevie.g]

Do you need a 750w power supply at minimum for 3000 series or 4000 series gpus?

Depends on which GPU. A 3060/3060ti will run fine on a good quality 500-600w psu. Would suggest 750w for a 3080 and above.

Right now for the 40 series (4090 specifically) a 750w is like a bare minimum but is cutting it really close with higher end CPU.

No, you don't. A 550w PSU is perfectly fine for midrange cards.

For 12400F and 3060Ti, it recommends ~450w. I would go with 550w to be on the safe side and because PSUs are more efficient closer to 50% capacity utilization.
