Yeah, I red about it a year or so ago, maybe some changed something by now. Just thought about another thing that should be considered and it's how many output rails it has at +12v. Let's take mine that I'm using now. It's Sharkoon Silent Storm 660W. SilentStorm CM | SHARKOON Technologies GmbH It has 4 rails of 18A each and that means It can't put out more than 18A @ 12v per rail. If I had GPU that draws more than 18A it would be not enough, Same thing on any other rail. So that's another thing that has to be considered. If you look at it's data you can see how its divided.
