Kind of a trend, the amount of youtubers who i had loved but their content became generic after gaining popularity is quite a bit, most drastic one being mrwhosetheboss, his uniqueness went down faster than MH27 MH17

    But a shitty $50 no name PSU is probably gonna blow up before the $150 unit from a solid company with a well established history of quality parts

    Nope haha, I don’t know if you know, but Evga, Corsair and Gigabyte already had their issues with entire series of PSUs exploding, all those had the issue that the active pfc diode/transistor were failing.

    You will never have that issue if you buy a very low end PSU that is NRTL certified (plenty of sub 40 usd PSUs do) because they don’t have active pfc to begin with.

    quality parts

    At most maybe the more expensive PSU because it has better quality capacitors will last longer before the PSU will eventually refuse to turn on due to the caps degrading, but at no point it will explode.

    But the transistors, resistors, diodes, etc are all the same quality, there isn’t a quality difference in those.

    They are also “better” in the sense that they usually have less ripple and better regulation than their cheaper counterparts, but that does not make them safer, in fact it is the opposite:

    High end PSUs have DC-DC regulation, that is the 5V is taken from the 12V instead of it being its own output from the transformer winding, you have to hope that they implemented the supersivor IC right in these PSUs, because in DC-DC PSUs there is the posibility of a 5V failure resulting in 12V in the 5V rail if the 5V regulator fails. With cheap group regulated PSUs this isn’t possible because all regulation is done from the primary transistors and if anything fails the output voltages will just drop to 0V.
