What real power should the x299 / 7820X / gtx1070Ti power supply have?

My configuration Asus Rampage Apex / 7820x @ 4.5GHz / gtx1070ti.
The stress test RealBench -> 453 Watts of reality max.
I need a quiet and trouble-free device.
The Corsair AX / HX series so far in my case is a total failure.
(4xRMA for two weeks each and 120 USD for shipping)
Suggest the optimal choice of configuration /
Seasonic Fanless 600W (without fan)
against
Seasonic Prime Ultra 750W (semi-passive)
against
Seasonic Prime Ultra 850W (semi-passive)
(Due to my location and availability of warranty service, I do not take into account other producers who do not have representative offices in our country)
:confused:
Maybe the above-mentioned is an exaggeration in this case, is the Focus series enough?

Seasonic is a solid PSU. My choice would be the 850W for future upgrades (like SLI).

But if you plan to run only one graphic card, then the 750W should be fine.

750W is currently unavailable on sale. I bought 850w, as suggested. Thank you for your interest in my question.
