    Silverstone Nightjar 500W 80plus Bronze certified fanless PSU. Main topology used in this unit is Active Clamp single switch forward. I wonder why it only does 80plus bronze whilst featuring technologies such as DC-DC converters and Sync-Rectification.

    Police arrest two kids. One was drinking battery acid, the other was eating fireworks. They charged one and let the other one off.

    At low loads the efficienty isn't high enough.

    It's a pointless PSU anyway, unless much cheaper than both X-460 and Stryker/Golden Silent.

    84% at 20% load wasn't bad; but I agree. Nothing spectacular there.

    I'd much rather have seen this guy do 87% efficiency at 20% load, then fall to 84% at full load.

    80Plus has it Silver, but SilverStone is only advertising it as bronze since the unit is borderline and they feel 80Plus' results are atypical and not able to be guaranteed on every unit. According to SilverStone, their main concern was not efficiency with the unit but longevity and since longevity is more important to users than insignificant increases in efficiency they are correct to focus on it with a fanless unit.

    Thanks for the explanations, guys.

    According to the report, the recommended price for the PSU is €129. That's a little pricy IMO.

    Edit: More pictures of the Nightjar 500W PSU. OEM probably is Seventeam. There's a ST marking on the little transformer-like thing between the main transformer and the primary side heat sink.

    It's definitely a Seventeam unit. They showed off the same unit earlier this year in Taipei.

    Like wise, a new Zues unit is supposed to come from Seventeam/Silverstone.

    Internals of the FSP AU500FL fanless power supply. It applies a complete different topology (LLC) compared to the other Aurum's (ACF).
