Rtx 4090 and 1000 watt psu?

[Random_Matt]

3 pin = safe with 850w. (Standard RTX 4090 450W default power)
4 pin = safe with 1000w. (Mid range upwards have a 600W max power limit) (Includes the FE model)

Each pin is 150w

PCI Express is 75w

You can just use 3 pci cables if you wish on any model.

Don't use Newegg. https://outervision.com/power-supply-calculator
