Then that's something reviewers should go over
If we have information about data sheet reliability, why isn't that something that is discussed in tear downs? I know resistors have data sheets, but do those data sheets have info on reliability or not? I recall reading about the cored bands on resistors, too.

This is stupid in so many ways.

True you cant identify the resistor spec sheet by looking at the resistor. So it is impossible. Plus it really depends on the design and how they're implemented. Nor do they have the time, money, or knowledge to do so since PSUs are designed by a team of engineers over an extended sive period of time, which a single reviewer cannot analyze to full thorough analysis.

One of my PSU's has a lowspeed fan when it idles. I can't even hear it when it is running, and it's not even in a case. I think Stephen is right about this.

Yes you can lol

Looking at it, you can get some nice bare essential info that every engineer would use.

Colour stripes show the resistance, and usually you can see how much power it can dissipate by the size of it.

For surface mount resistors,. A chart to read that 3 digit number is essential.

You don't need to curate a resistor for an application with x brands or anything - usually the cheapest reels will do, or whatever your supplier gives you with the correct resistance and size.

Also, if a reviewer went super in-depth on everything, you'd get a university style lab report thats over 300 pages detailing the entire psu. Who's going to pay for it let alone read it for a psu

I'd also say Stephan is right. I'd rather the money go elsewhere in a PSU instead of semi-passive honestly.

Stephan is right about a lot of things. His analytical approach to capacitors I really like. Because really, numbers and data sheets are all we really do got. An argument backed up by a data sheet is better than one backed by nothing but personal thoughts and beliefs.

Yep I remember reading about that in an "electricity" textbook which I had to put down because it spouted crap and lies like "an electron will flow from one place on the wire to another at the speed of light".

Well that's partially correct - it's electrons moving around in a wire, flowing from negative to positive.

Yes but the electrons drift very slowly, like the speed of a potato bug. Not even close to the speed of light. It's the energy that moves at the speed of light around the wire.

Because we all know that manufacturers never lie about the specifications.
