Otherwise, everything looks neat processed, the only shortcoming is as already written often here was the cable are a little hard, a little soft tick would have been ideal, but it is it is not as if one bends an iron bar: -D
750W with a much more important ampere rating on the 3.3V and 5V rail.
Who buys this power supply makes definitely nothing wrong
Running does it with an i5 3570 and a Gainward 570GLH card.
Absolute buy recommendation
