I wouldn't go by models on this list as they need an update soon I think, but the brands in tiers 1 & 2 generally give you a good PSU, but even then you should look at reviews of the power supply you looking to buy before making a purchase as even good brands may have bargain models.

It comes with experience, I read reviews of everything I buy before i put it my PC as I am paranoid about wasting my money, and avoiding problems. I used to go looking for problems and caused a few of my own while trying to avoid others. A little knowledge is a dangerous thing.
NO brand is perfect, everything will break down eventually. But if you buy good things to begin with they save you money. Bad PSU can kill other things along the way.
