I am building a new rig and want a stable PSU that is Modular and not a wasted 1000 Watt monster, made by a good name like Silverstone, PCP&C ect.

why would you even ask this question? 750w is obviously enough for the system you mentioned.......60a on the 12v

What I want to know is it better to have a PSU with 4 30+ amp 12v rails or is it bettter to go with a single big 12v rail like this.
