I dont personally hold with the tier list at all ,it drives me nuts when people use it to be honest.
Ill recommend psu's based entirely on budget & location in the world - some people are simply unable to source what you would call top end psu's where they live which is where these budget mid range ones come in over some of the generic non branded ones with 'gold 750w' in the model name that are less than 70% efficient & have the 12v output of a 400w max.
At least with a branded model like this you can be sure youre getting a real 600w psu that has a reliability factor & real 600w output.
Ill stand by that statement 'burn down the house' is just entirely over the top & untrue seriously.
Take any consumer electronics item apart from maybe panasonic & sony & youll find a plethora of cheap chines/taiwanese manufactured caps & resistors to downrate the minor voltages.
theyre plenty good enough for this purpose as they are in the majority of psu's ( as long as theyre only used on the secondary filtering stage)
