Your statement 'Most new graphics card need 1 or 2 direct power connections
and this means a 300w PSU just won't cut it anymore.' isn't necessarily
true; a 300 watt PSU may very will be completely adequate.

Your statement 'if you have a too high rated PSU and are not drawing a
significant power level the PSU can shutdown, act erratically, or blow it's
12v rails through 'overheating' is not at all true.

Your statement| 'You want at least 20% more power coming out of your PSU
than the calculator says you need to be safe from the typical fluctuations
you can get in a PSU, especially cheaper PSUs that might not have a stable
power profile.' makes no sense at all.

Your statement 'Over 65% more power means you are at risk of damaging your
PSU through 'overheating' as it's generating a lot more power than you
need.' is ludicrous.

Pay particular attention to:
"System power supply needs vary widely depending on factors such as the
application (that is, for desktop, workstation, or server), intended ambient
environment (temperature, line voltage), or motherboard power requirements."

If you draw too
