How much power supply for 5900x and rtx 3080

[steverebo]

My rm850w psu just went pop and im having to return it to but the retailer is out of stock and im struggling to find an 850w psu.
Would a high quality 750w evga G5 psu be enough to handle a 5900x with 4x8gb ddr4 3600 2 nvme drives and an rtx 3080 founder edition overlclocked to 2150=2200

That’s pretty much the ideal wattage for your needs. The only reason you’d want more is if (not unreasonably given process node shrinks are becoming harder) you expect power draw to increase over the next few years.
