PSU important question

[Pelasgos]

Greetings,
I recently got the msi gtx 970 gaming, i5 4670k cpu and the gigabyte z170 gaming mobo.
My psu is the Chieftec cft gdf 850w.
I learned from a friend that the psu must not have a significant "rippling effect" ( its how steady is the voltage it gives) or the psu will fry the other parts.
Do you know FOR CERTAINTY if this psu is good? Because I dont wanna destroy my new parts.
Please inform me, I cant find anything online about this psu.
Tha k you.

Is the evga 850 G2 perfect for my pc?
By perfect I mean uninterrupted steady voltage without power surges even in milivolt or microvolt scope.
Please inform me.

By what you mean by perfect, there is no such power supply in existence that is even remotely in the same galaxy as that. The best consumer power supplies in existence that cost the most have +12v voltage deviations somewhere in the 0.5% range (which would be 6 mV). The ATX spec is 5%. Less than a µV? Umm...no.
