Finally the prices of 3080's and 3080ti's have come down enough to be within my reach - barely. I currently have a Corsair RM850 850 watt gold+ psu. Do you think that will safely drive the above cards? It has all the required power dongles.

The video cards I was specifically looking are the EVGA FTW3 Ultra 12gb 3080 or 3080ti. I know a 1000 watt psu would be better, but they are actually a bit scarce in my region, and I would prefer not to have to upgrade the psu (and so have to re-do all the power dongle runs) if I don't have to.

EVGA recommends using a 750 watt psu, so in theory my 850 watt psu should be enough, and the various psu calculator sites I visited say it should be enough, but I wonder what people here think, especially those with actual experience with both in MSFS. 

Thanks - Bob

I personally have a 850 seasonic PSU and it drives an Intel Core I7-12700KF at 4800 Mhz and a FE RTX 3090. Never had any problem.

I am doing just fine with a Corsair Gold 850W PSU.  My 3080 is the 12 GB variety.  My full system specs are below in my message footer.

Thanks for the replies. That answers the question. I was just a bit nervous after reading the card's power draws.

Thanks again - Bob
