how many watts do i need for my build

[mrfredo18]

https://pcpartpicker.com/user/MrFredo18/saved/qCmvVn i was thinking 650 or 750 but i don't know if 650 is more than enough

so i was looking at seasonic 650 TD or 750 maybe even a 850

go with the seasonic 750w. that setup will use about 50% of that which I believe is the best efficiency point for psu's
