EVGA makes some higher end psus, but that is not a high end psu. It has 4 12v rails, less being better. Highly recommend 1 rail, 2 is acceptable in some cases, 3 is bad, 4 is dangerous.
A much, MUCH better psu, but its more

Powersupplies are parts you dont want to skimp on, as they can take a whole system out sometimes.
This is horrendously wrong, like absolutely attrociously wrong, you have been drinking Corsair/XFX's kool-aid a bit too long.
Multiple rails are not a problem, single rail isn't better than a well designed multi rail unit, and 4 12V rails sure as hell isn't "dangerous" it is actually slightly safer as you have reduced the power you can dump into any point before you trip the power off, no PSU rail configuration is "dangerous". Check the links in my sig, i have covered the single vs multi rail debate before, but it seems the FUD has made a comeback.
The EVGA super novas have not been reviewed by any of the main sites yet so we don't know how they perform, the one review i could find it seemed to do well, but not having read through other reviews on that site i can't say how they compare to HWSecrets or Jonnyguru reviews.
The Rosewill capstone series is a better PSU, but it is also 1.8x the cost so of course it is going to be a better PSU, but you likely don't even need a 750W unit, 550W will do most single GPU systems and you can get those for notably less.
