Dave really called it.. so many people with their nickers in a twist about a damn computer.
Because there is so much Misinformation, Bullshit, Lies and Fairy tales in this area you can write books about that...
And now a highly regarded electronics person does all the things those People are fighting against...
That's one of the reasons people are posting here right now...
Epecially in the PSU area. Like the lie of "Single Rail is better, Multi Rail is garbage*", bigger fans equal lower noise (no it doesn't!), Efficiency equals quality (well, there is a bit truth to that -> there are no good quality 80plus Bronze or worse PSU right now. The best bronze ones are just somewhat OK right now because Gold is like 2,5€ more in manufacturing), that the manufacturer is the most important thing...
Or stuff like you need a 750W PSU for an office PC (well, in ATX Formfactor, there are no really good PSU under 400W), should be loaded only up to 50% (when the good PSU are rated at continuous power at higher ambient temperatures, usually 40°C, sometimes 50°C. The Cheaper ones are only rated for like 30-35°C Ambient).
When we come to Graphics Cards and CPUs, it doesn't get any better.
The worst thing I've seen is that people believe that nVidia Cards are for Intel and don't work well in AMD Systems or vice versa with AMD Cards -> people believe that they only work well in AMD Systems...
*That is essentially Multi Rail in a PSU:
(Pic of a 14.95€ PSU
)
A Shunt Resistor or a coil per Rail, a wire per Rail to the supervisior (or something like that like an LM393). And just some way to limit the current for a certain set of cables. And switches it off, if it is over the set limit.
PS: For the Electronic Nuts who want to learn about Power Supply Stuff and are pretty bored, google Texas Instruments UCD3138A.
And that thing is already used in some higher end Power Supplys today. And has has a 31,25MHz ARM7 Core...
