Corsair TX650M vs SilentiumPC Supremo FM2 750W

[Tortt11]

Would corsair TX650M be enough for RTX 3060Ti + Ryzen 5 3600, looking at the leaked 3060Ti specs (and that it should be kind of like RTX 2080 Super)? I've checked some PSU calculators and both barely exceed 400w. I could in theory give the Corsair TX650M back since it's unused and waiting for 3060Ti and get SilentiumPC Supremo FM2 750W which I haven't seen before but I'm not sure if I should bother. I read a bunch of conflicting opinions like "solid 650w is enough" or "get 750w to be safe".

At the very best it would be about 250W GPU, combined with 100W CPU and other components that's just about 400W, you don't need 750W PSU for that, 550W is a plenty.

TX 550W is fine yeah.
