    Default Heavier PSU = better?

    this video in spanish says that

    https://www.youtube.com/watch?v=40PBMWO0gj8

    I think not

    but I'd like a more in-depth explaination that highlights what components make a PSU heavier


    he also says that you can also guees it's a bad PSU by looking at the amount of connectors it has

    Ah wait, you mean heavier as in the weight, not the total wattage. But that's also not true indeed.

    No I thought you meant that more wattage is better, instead of a heavier. That's why I edited my post with an extra sentence.

    Bitfenix Formula is pretty light but good.
    Many Bronze units are heavier and shittier.

    So no, that's a lie that came to life in the early 2000s and was nothing more than to say get a unit with pPFC, wich is heavy instead of a no PFC wich is lighter.
    It became a lie when aPFC became a thing. Because aPFC is lighter than pPFC due to the way it works...

    pPFC is just a fat coil in the line...


    So no, its a lie.

    Heat sinks; a more efficient power supply may not need such heavy heat sinks.

    Aren't heatsinks made of aluminum? When it comes to heatsinks that cool CPU's, the fins are made of aluminum.
    Core i7 4770K @4.3GHz + iGPU | GA-Z87X-UD4H | 2x8GB Crucial Ballistix DDR3@1600MHz
    Prolimatech Armageddon heatsink w/ 2 x 140mm NF-A14 PWM fans

    Fractal Design Define R5 case w/2 x NF-A14 ULN front fans | no exhaust fan; grill removed

    Not so much material, hence heatsink density, but the size or even if they're used at all.

    Some +12V FETs are so efficient, they're just bolted to busbars. Some are just mounted to the bottom of the PCB so they sink to the PSU housing. That's some significant weight savings.
