How the tier was reached

  1. MISSED

    Tier A - reference classspec 12.9

    • Primary conversion stage: Legacy primary topology (DF)
    • Secondary rectification: Passive (Schottky) rectification
    • Minor rail regulation: Group-regulated minor rails
    • Efficiency certification: No efficiency certification claimed
    • AC input range: Restricted 230V-only input
    • Too many failed criteria for this tier (5)
  2. MISSED

    Tier B - strong mainstreamspec 12.10

    • Primary conversion stage: Legacy primary topology (DF)
    • Secondary rectification: Passive (Schottky) rectification
    • Minor rail regulation: Group-regulated minor rails
    • Efficiency certification: No efficiency certification claimed
    • Too many failed criteria for this tier (4)
  3. MISSED

    Tier C - adequatespec 12.11

    • Minor rail regulation: Group-regulated minor rails
    • Too many failed criteria for this tier (1)
  4. MISSED

    Tier D - basicspec 12.12

    • Minor rail regulation: Group-regulated minor rails
    • Secondary rectification: Passive (Schottky) rectification
    • Efficiency certification: No efficiency certification claimed
    • Too many failed criteria for this tier (3)
  • Insufficient evidence, unknown platform or unsatisfactory architecture (spec 12.13)
  • Modifiers do not apply to E and F

Missing evidence

These criteria could not be resolved. They lower the confidence index rather than count against the unit.

  • Active power factor correction
  • Electrolytic capacitor temperature rating
  • Fan bearing type
  • Protection coverage
  • Over-current protection declared
  • Over-temperature protection declared
  • Protection trip points
  • Measured electrical behaviour
  • +12V ripple
  • Voltage regulation
  • +12V transient response
  • Platform attribution
  • Independent laboratory evidence
  • Manufacturer warranty
