    Default Seasonic Prime Review at Anandtech

    The Seasonic PRIME Titanium PSU (650W, 750W, 850W) Review: Mythical Performance
    by E. Fylladitakis

    http://www.anandtech.com/show/11252/...-supply-review

    "In this review we had a look at Seasonic’s latest top series, the PRIME Titanium 650W, 750W and 850W PSUs. They are not the most powerful models on the market designed for quad-GPU beats, but they are the technologically best units that Seasonic is currently offering to consumers.
    .
    .
    .
    Seasonic made it easy for us to summarize the entirety of these units’ performance in just one word: mythical.
    .
    .
    .
    Before testing these three units, we would not believe that such performance would be possible with a consumer-grade PC PSU."

    I wonder why reviews have perfect voltage values but in the 80 Plus Report they are shitty

    WTF?

    The oddity (for unexperienced readers like me) is that under load those Prime's 12V readings goes up, not down.

    Not odd at all. Sense wire and LLC topology.

    May you kindly point out another fine example of that not odd at all behaviour, Jon?

    I've seen it plenty of times.

    I guess there might be a misunderstanding: in my point of view, the 12V rail barely moves on that AX1500i.

    Let's give a look at Prime's Ecova findings:



    I mean, according to me it looks (12.24-12.46V) rather different than the AXi behaviour (11.96-11.98V), but obviously I may be plainly wrong about that.

    I wouldn't trust ECOVAs voltage results. Even on known quality brands, their results have never been consistent with reviewers.

    it depends on which pin you test and the pin you load, the sensor pin will keep the voltage close to setting point under different loading.

    And so what? I mean, which is the "real" 12V load regulation?
