Seasonic FOCUS Plus Series 850 Platinum vs Cosair RM850x Gold

Hi all I'm kind of split on these two PSUs and need input on what an extra 5amps from the Cosair would even do. Benefits of the Seasonic are better power efficiency as far as I can tell. They are both priced similarly so I'm not sure which to go with. Thanks for any input.

I think the Version 2 of RM850X has worse transient response on +12V

+12V Load regulation is worse than Focus Plus platinum unit as well but ripple is a bit better

You can turn the hybrid fan mode off on the Seasonic if you want you cant on the RMx its always in hybrid mode no matter what which means it tends to run hotter
In my opinion having the option to have it on or off is a plus so i would go for the Seasonic for that reason

Seasonic PSU's always all the way. I have # of systems (12worksattions) with PSU's ranging from 700-1200Platinum, in 10 years none ever had issue and ripple is spot on.

I'm just waiting for their 1600Watt to be released, Its my next purchase.
