Anandtech published The Cyonic AU-550x PSU
A quote from the article:
In this review, we are getting acquainted with a new PSU manufacturer, Cyonic. The newly founded brand offers just six units at this time, three of which are modular and three are of classic design, with power ratings ranging from 450 to 650 Watts.
