Wow, man! And you got these from your 112 years (from your basic info) of experience?! :cool:
"Fact a computer runs cooler and is less likely to present errors with a good quality power supply." I agree with the "...is less likely to present errors with a good quality power supply." part, but I have some thoughts about "Fact a computer runs cooler..." - this depends on the case design. Most of the modern cases are design in a way that the psu has it's own air circulation: getting air from outside (bottom) and exhausting outside (rear). In this case, how the computer run hot, even with a hot psu?!
"Fact anything over 850 watts is complete hype with the exception of dual processor server systems or systems with more than two graphics cards." - pretty much, I agree. But, hey, do you know that feeling to know that you have more reserves? Specially, when you're planning to have an upgrade - like put in more graphic cards, OC, get more fans, or more pumps for your WC.
"Fact processors and video cards once again are becomming more energy efficient with the exception of AMD at the time of this posting but AMD is soon to follow. This means less power is required." - Well, see above! Heavy OC and/or multiple high-end graphic cards still require more power...
"Fact gold rated power supplies run cooler than bronze rated and platinum is just a way to charge you more for little differance over gold." - I would be interested in founding out how did you get to this conclusion! As I said above, why is the psu temp matter if it has completely isolated airflow from the rest of the system? Gold rated psus are higher quality than bronze rated ones (at least that's the idea making them), as platinum rating is higher than the gold one - it depends on your pocket which one you will get. But let me tell you something! You may have even the highest platinum rated psu if you don't have proper power protection (like a good ups)...
"Fact Seasonic has always been a well regarded power supply company amongst all the new brands." - OK, so?
"Fact Corsair are likely rebranded slightly modified Seasonics." - So, what's the problem? If "Seasonic has always been a well regarded power supply company amongst all the new brands."
"Fact Antec made good power supplies then started making worse ones but are now back in the game making pretty decent stuff since Delta Electronics now makes their power supplies." - If you say so... Never had any experience with Antec psus, but will keep this in my mind, in case i will need an other psu.
