Back in 2009 when we originally released our HX Series power supplies, we listed in their specifications that they met and exceeded the standards for 80 PLUS® Silver certification. Many reviewers and PSU aficionados quickly discovered that every unit tested and reviewed in this series actually met the standards for 80 PLUS Gold certification.
We knew this of course but we also knew that we could not guarantee that every HX Series PSU that hit the shelves would always meet the 80 PLUS Gold standard to our satisfaction. So, we intentionally chose to apply a conservative rating and list our HX series PSUs as 80 PLUS Silver units.
