Pros

On that subject I was looking at the CORSAIR RM850x ATX 3.1 as a replacement. Its also 850 watts, so do you think that'll be insufficient?
PSU: Corsair RM850x ATX 3.1
Corsair themselves officially recommends Cybenetics for quality testing: https://www.corsair.com/newsroom/press-release/corsair-transitions-to-more-comprehensive-psu-certifications-from-cybenetics
I know Corsair might be not the best price/value but I like their PSUs.
Better platform and noticable better electrical performance + better support. Reliability wise both last long. RMx is superior.
