Philisters and science
  • If you look around, people made lots of tier lists, for example for PSU capacitors - https://www.tomshardware.com/reviews/power-supplies-101,4193-5.html .

    Yet it is completely philister, anti scientific point of view.

    First - it is idiotic and static brand generalization. Each of brands have lot of capacitor lines made for different purposes and with different construction and prices. And it all changes constantly. Plus each brand has periodic problems with some specific capacitors, usually not big, but shit happens.

    Second - properly selected and cooled 105 degrees Chinese/Taiwanese capacitor can live 10-20 times more compared to improperly placed 85 degrees Japanese one.

    Third - capacitors life also depend on quality of PSU design, air flow, ripple, etc.

    Fourth - top PSUs usually are designed for long work under load close to 90-100% of their specifications.
    Yet, heat generated inside cheap Bronze class PSU will be around 30W for 300W real load with 550-600W PSU, and such PSU usually have much more space. For top expensive Titanium class PSU that many get to work at 570W (multiple top GPUs and such), heat will be around 47 watts with more crowded construction and more silent fan. Such PSUs really need top capacitors for long life.

    Simple example, OCZ (now out of business) made ModXStream PSUs that liked to fail right after warranty

    Initially they used more reputable (among Taiwanese :-)) Teapo LH 85C capacitors. Yet they failed and fast. Most probably reason - very low fan speed and bad location with two hot yet flat heatsinks.

    After this they switched to Transcend Electrolytic (Trec), not small company, but not regarded at all. Yet it behave much better. All PSUs I saw with them worked for >6 years without hitch.
