but your whole recommendation is wrong
you don't only equate 80+ gold with good components and reliability but you also talk about "reliable" brands
first of all: what are reliable brands?
in my opinion: there are none since there is not a single brand that doesn't have bad PSUs which means no brand has 100% good PSUs
let's look at brands generally seen as reliable
brands that come to my mind: EVGA, Super Flower, bequiet, Delta, FSP, seasonic
All of these have PSUs with low quality components
So what brands are actually reliable?
"you associate these same characteristics with the 'the more expensive, the better', which indeed does not necessarily apply."
Show me a 200 euro PSU that is worse than a 100 euro one (same power rating). I'm waiting.
