EVGA 430W with a Ryzen 5 1600 and a rx 580 4gb? CYberpowepc says it should be. i also won't be overclocking
"Tier 1" the way the industry means tier 1. Not the way this list means tier 1.
Tier 1 in the industry is someone like Delta, Flex, Chicony, etc.
Believe it or not, someone that outsources PCB-A like Seasonic and Superflower are actually considered Tier 3.
Tier 2 would be guys like CWT and HEC.
