Corsair RM850 on a Dark Hero + RTX3090

Hi There,

Just need to put my mind at rest.
I'm building a ROG Dark Hero with a 5900x and Nvidia Geforce RTX 3090.
I think 850w will be fine but someone said the RM850x has (Japanese Capacitors) which has better reliability.
But they both come with 10 year warranty?

Thanks, Even If it went pop after 9 years I'd still be happy with a replacement
