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

**Zbigniew** · 07-23-2018 09:09 PM

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)

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.

750 -> 850W psu.

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