Ok, any recommendations? Thanks
I really don't know, PSUs are difficult, every brand puts out good ones and bad ones.
I only go for the best one with longest term warranty for my main build, I never skimp on PSU.
So my recommendation would be an EVGA Titanium series with 10 years warranty or equivalent from Corsair or Seasonic.
Other people are going to come in and whine that I'm overspecifying the PSU always. If you're paying for a high end GPU you also pay for a high end PSU imho.
Seasonic is generally regarded the best, but that doesn't mean their low end units, it means the equivalent top models.
High end unit with 750w should be plenty for 3070 Ti plus overclocking everything, but might not leave much headroom for anything higher later on.
My OCed 10900K and 1080 Ti build pulls 649w at maximum stress test load confirmed by a wattage meter. If 3070 Ti uses more power than a 1080 Ti then I wouldn't say 650w is enough of you also want to overclock.
