The PSU is only going to pull from the wall what it needs to pull in order to deliver the amount of power that the system is pulling from the PSU. So an 800W power supply is not constantly pulling 800W from the wall outlet. If the system is pulling 300W from it and if the PSU is 85% efficient, then it will pull about 353W from the wall outlet. This will change very slightly between a large capacity PSU vs. a smaller capacity for technical reasons (there's a sweet spot where the efficiency is maximized), but generally it's not enough to worry about when comparing quality-made power supplies.

should i go for 2133MHz CL11 or 1600 CL9 or 1866 CL9 RAM ? i kind of dont understand the diferences in latency and impact on performance with i5-3570K, also there is CORSAIR 8GB KIT DDR3 2133MHz CL9 Red Vengeance (CMZ8GX3M2X2133C9R) i like that one pretty much but will it fit under Noctuna heatsink ? is it worth 40bucks extra ?
