Not sure until they come out but 1200W PSU isnt required for a 2080ti

Your assumed prices are way to low. The Nvidia RTX 3080Ti will go around 1300 to 1400.00
My Evga 1200 goes for around 325.00

Not surprising.

....unless you think a cheaper, lower power supply will work....which I doubt.

My answer to this is in my system specs

And I thought that example would be self explanatory, but...

Yes I know Doug, but we are talking about a Nvidia GeForce RTX 3080Ti card now.

Yep, time will tell

My main point was ....my PS is big enough to power anything I throw in my rig.

Until the 3080Ti requires a GiGawatt

And powerful enough, to where the fan doesn't need to run, sucking fine dust into it

I'm sure the 1000 watt version is enough.

Anyway if one has to upgrade their power supply to get one of those cards then than cost of ownership is actually the GPU + PS. Example $799 for the card + $200 for a PS would actually make the cost of card $999.

But, as I said before, I doubt you're need to get a new PS, but rather an adapter cable should be included with the card. Or in the case of most modular power supplies, you may be able to get/buy a separate cable for the card(s).

Ampere is 7nm vs 12nm Turing, so should consume less power. that will probably be made up by increased transistor count, but I doubt these rumors about a 12 pin power connector.

Also, you can't just use an 8-pin to 12-pin adapter cable. The 8-pin l cable is only specified for so much current. If you need to go to 12 pins it is because 8 pins can't provide enough current. If you were to put an 8-pin to 12-pin adapter, you would draw more current on the 8 pins than it is designed for, and probably melt the connector under a sustained peak load.

Most high-end PSU above 650W-750W can provide four 8-pin PCI-E power, with each 8-pin being 6+2 . You can get two 12 out of that. So IMO they will use existing connectors on PSU and if you have a 4x8 you are jake. Certainly too late for a new PSU

PSU over 1000W really are not needed unless you are running 2 highest end graphics cards and overclocking. I don't think that will change.

Actually you could if the design is right - unless you (the vendor) have a new power supply design in mind.

Anyway until the card is actually released or seen and tested.... it's all rumor mill and guesswork

My two cents.
