Using 2 PSU has CLoD kicking it in high gear!

No, hardly not. General overwattage is backed up by fuses, and genreally, if you overwatt one rails then you probaly get voltage drops on the other rails, causing instabilities.

The maximum wattage of the PCIe Slot itself is about 75 Watts, a 6 Pin PCIe Adaptor is rated for (aditional) 75Watts itself, whereas a 8 pin PCIe Connector can handle 150Watts max.

So even a 590Ti card with its 2 8 Pin PCIe connectors cannot draw more than a theoretical 2*150+1*75Watts=375 Watts theoretical limit that the power adaptors itself can safely handle.

The "needs a 550 Watt" psu recommendations are just a safe margin.
You can have scenerios where you draw more watts, say on the 12Volts rail of an psu than the psu can handle even as the complete watte of all rails itself isnt reached. Thus we get this rather high recommended (complete) wattage.

It was a pleasure

If saying the thruth is beeing an asshole in your view than.. call me one, no problem.
If you would have read my text you might have been able to get the "seasonic is a good brand" message, but maybe it was just hidden too deep. The wattage itself depends on the system you are running. But a single 4GHz Quadcore intel with some hdds/opical drives (that are in the sub 20 watts area, more like even under the sub 10 watts) and 1 or 2 GPUs is hardly asking for more than a good 550-650 Watt PSU. Even under spiking.
