    Default Pichau Gaming Nidus 500W review @ TechPowerUP

    https://www.techpowerup.com/review/p...g-nidus-500-w/

    Pichau is a large distributor in Brazil, a country with more than 210 million people and, thus, a huge market for every brand out there. Like every significant distributor, why only deal with products from other brands and not create your own? Enter Pichau Gaming. Since power supplies, especially the affordable ones, are a crucial part of every brand, Pichau recently released its own PSU line, which, for the moment at least, only consists of a unit. That having been said, Pichau made the proper call by starting with a mainstream model because such models sell readily in high numbers for the necessary cash flow to develop other PSU models.

    I swear I read "Pikachu" when I first saw that.

    Maybe they will get to designing their own, although rebranding makes sense at least for the start.

    "ten minutes at half load and 230 V input, the temperature of the bridge rectifier doesn't go above 85 C"

    That scares me; now use full load at 110V and one is pulling 4 times the current.

    Ah, thanks for the clarification; I guess I misunderstood


    Specifications

    Semi-passive operation: No


    and had not realized that the thermal tests were done with the fan removed...

    Thermal testing with the fan spinning is hard to do because the fan blocks the IR.

    Good point, but then thermal imaging is meaningless.

    Well, it can be proof temperature is harmless like it's here.

    Absolutely fascinating is the running at high temperature for efficiency

    "
    The single bridge rectifier is not bolted to a heat sink. This might look odd, but allows for higher efficiency since with higher temperatures, voltage drops on the diodes the bridge rectifier contains are lower.

    That sentence structure, though.
