We are confusing our selfs , by mixing technical info and ppl , good or bad .
Every brand with one working product and good after sales service are called : " Good "
Every PSU, that had pass certification and comply to regulations standards , its " Good "
Every PSU , that the label on it as Watts , agree with the delivered power , its " Good "
Thats the theory, from a spherical view.
The detailed view are more complicate.
Lets say that i build one PSU by my self , and like to promote it on the market .
Could some one calculate, what are the possibilities , of something to gets wrong ,
and my final customer be unhappy with me ?
And my list of things to go wrong .
Example 1 ) My electronics parts supplier , gave me bad quality ICs .
My PSU uses 180 good parts , because of the one , i will look as bad one,
to the end user.
Example 2 ) Transport accident .
( Lots recent ppl about newegg and damaged products , and lots RMA)
Justification : Transport accident
Transport accident clarification :
Many parts on the PSU board (horizontal position) , stands up (vertical position ).
One ultra strong vibration , could cause severe damage !!
Example 3 ) Product are good , buyer destroy the device , by dropping it down.
Or the all computer drops down .
Example 4 ) Product are good , electrical network damage , causes death on the device.
Good - bad , lives - dies , better - worst , all this thoughts , are coming from a total ,
of possibilities.
End of examples . . . . . . . . . . . . . . . . . . . . . . . ..
Now , technically speaking , the only solid criteria for proper PSU selection,
are the behavior of it, at clean DC - stable DC & if the protections (Over Voltage Protection) ( Over current protection ) are working.
So far the HIPER 4M780 , looks exceptional on this measurements .
Or i would say leading scorer .
BUT , even if it as leader scorer , at computers enthusiasts boards.
Its that picture true ?
No its not , because the amateur enthusiast , who did the review ,
he did not follow a basic rule on electronics , to use the advice of the manufacture,
of how to do a proper measurement with the oscilloscope.
Add 0.1uF and 10uF capacitors across output terminal during ripple & noise test.

If some one do that , he will find out , that
this HIPER model is even better.
So my tip is , study study study and investigate , so to have a true motive for your next buy, what ever is that .
