Yes, "really". I was responding to your post at face value (I honestly thought that you didn't have a clue) so I attempted to let you be aware of a fact. That's all. If "discover" touched a nerve in you, that's too bad. If it makes you feel any better, I hereby retract "discover" and substitute it with "find out".
It's not "first rodeo" for the majority of us in here either. Therefore, the common knowledge that the quality of a PSU affects its performance is nothing new in here (or any decent tech forum for that matter) and is not exclusive to you.
To reiterate, contrary to your post (verbatim) that I originally responded to, it's a fact that the S3s have been successfully overclocked using 500W PSUs utilizing only two PCIe power inputs for each unit. I refuse to allow disinformation to propagate.
Since we're all retract-y here, I'll choose one that actually might make a difference: I hereby retract my "a" and replace it with "your" when I was talking about the 650.
Note that I never disagreed with your assertion and even referred to it later. Nevertheless, I still think my response will prove to be helpful, which was my only intent. If you disagree with the crux of the advice (better or more power might be worth investigating), that's fine, but if you didn't then indulging in pedantry for the sake of a side-point just distracts.
Like I said, your OP that I originally responded to appeared to be more of a declaration which is at odds with a known fact rather than an opinion based on a personal experience, hence my attempt to steer you towards the right direction. That's all. However, you've cleared that up since then in your subsequent reply. No need to get defensive. We are all students of the game in here.
As for being a pedant, I wasn't the one who was very particular about and pointlessly quoted "discover" with quotation marks.
