I had an older desktop with a top of the line Seasonic 80 Gold Plus PSU (8yrs or so) which is rated 750 watts and 62amp on 12V.

Would this do fine for RTX 5070 Ti or 4070 Ti Super?

I am building with a Radeon 9 7900 (65w) CPU, 32gb DDR5 RAM, 2xSSD, 3xHDD, and an ATX case with 4 fans.

The power calculators say between 650-750 should be fine but I want to make sure it would be running ok based on real life experience and also the age of the power supply.

Thanks
