Rtx 5070Ti on Seasonic 650w B12 Gold

I currently have a Seasonic B12 650w PSU and I want to upgrade my GPU to 5070Ti.

Should I consider changing to a higher wattage PSU also or would the current one be sufficient.

Current PC specs:

AMD R5 7600x

32 GB DDR5

Asus TUF 650B mobo

Samsung 770 evo pro 1tb m.2 (I might be mistaken for the series but I know it's samsung evo something)

rtx 3070 2x MSI Ventus

also I have 3x front fans and one for the CPU cooler (it's the classic cpu cooler, non water cooled :D)
