1. RTX 3070ti LHR
2. RTX 3060Ti non LHR
3. RX Vega 56
I'm not so sure about this that's why I decide to ask, the power supply is a Corsair build from my gaming desktop.
Corsair is a great brand and the one I love,I also personally run all my rigs on Corsair PSU-s but the golden rule is that a power supply should not be pushed over 80% of its full capacity.So there is a 200 watt consumption from the 3070 ti LHR in Ethereum mining and 120 watt for the 3060 ti as I have one of these cards and that is the power consumption of it,for Vega 56 should be 150 watt making a total of 470 watt plus 100 watt the motherboard and other parts making a total of 570 watt and that is more than 80 percent usage of the PSU thus shortening the life of it or causing intermittent restarts.A 750 watt would be better but still you are in very near that 80% capacity which is 600 watt in total.I would say get a 850 watt one and you are good to go and not worry even for the future.
