Why are power supplies so expensive?

Why are power supplies so expensive? They use literal off the shelf parts and there's like 100 different companies that make them, so shouldn't their prices have come down to basically just the cost of the parts by now? A $100 psu probably has $15 worth of parts inside it so it makes no sense that everyone sells them for such a huge markup. Even motherboards are cheaper than power supplies on average, and they use tons of custom parts and an infinitely more complex manufacturing process.

      These are just for avoiding lawsuits, because of remaining charge in the capacitors

      Do me a favor and shutdown your PC, open your PSU, find the biggest capacitor and touch the terminals.

    PSUs are one of the highest margin products in PCs
    moronic tech toobers have blown the "don't cheap out on a PSU" meme to such absurd proportions that basically no one questions it.

    It's known that PSUs are cheap, a 600w 80 plus bronze PSU is like $20 straight from Great Wall, but Corsair will turn around with the same unit, paint it black and charge $60-70

        basically every current mode switching IC made in the past 30-40 years will have cycle-by-cycle primary side current limiting.

    They don't seem particularly expensive to me, especially considering how long a PSU lasta and that you never have to upgrade it as long as you don't skimp out on its power rating when you buy it.

      I mean just a few ones that come to my mind are. Seasonic, FSP, Super Flower, Delta, Channel Well Technology, Great Wall, High-Quality Evolution Commitment, Flextronics and Highpower.

          Nowadays they are
          They let FSP jack their shit by basically doing little to update their power supplies.
          Boomer sentiment only goes so far which is ironic as it's another boomer brand taking the top spots now

          What's wrong with Seasonic? Their PSUs are good. Their service is great, I actually got a new one in exchange for an old one because by MB fricked up.

            Nothing wrong with them, it's just that they have been sitting on their laurels lately. They haven't bothered to really improve their models much as compared to other brands.

        wtf do you want lol
        more dairy lights?

        I want a PSU with builtin battery as UPS. Should be more efficient and less annoying than a separate UPS.

        are you daft lol
        with a separate one you can plug many things
        youre dumb as dick lol omg

          IDK
          Maybe some cheaper prices, lower noise output
          An 1000w FSP hydro ti pro is like $270 and is the best rounded PSU. Seasonic has nothing to compete with that.

    If you think Asus, EVGA, Deepcool, Corsair etc actually make their psu's you are wrong. In reality there are far fewer companies that actually make PSU's. And only ones that you have heard about probably are Seasonic, Super Flower and FSP.

    They have actually gotten cheaper. I have an old receipt from 2016 for a Super Flower 550W 80 plus gold non modular PSU. Shit was 87 euros. Nowadays for that money you can get an 850W 80 plus gold non modular PSU.

    At least fraudulously rated PSUs, without active PFC, or adequate protections like in the OP are pushed out of the market. Literal housefires.

    That's pretty much the standard mark-up that any larger manufacturer in the world puts on their products.
    Item costs $20 to manufacturer including r&d, packaging etc, item is sold for $80 to $140.
    it's not like you could actually build a pc power supply yourself for $20, it would cost you hundreds + countless hours of time for designing, prototyping, testing etc.

    Parts rated for high current are much costlier than normal due to their overall size for heat dissipation

    I mean imagine a 500W power source, that's 41A. If you want just to drive all this current through a single wire you need AWG 6

    Some parts are rated not just for high current but also high frequency for switching
