The unit itself isn't much suprise, standard of what you would expect. However, when I look at the 12v rail on the chart, it gives 35A. This is uncompareable by some cheaply made 600W PSU that goes on sale for less than $30. At least with this 450W unit, I can run a nice video card plus a decent cpu overclock while running 4 HDDs without too much worry.
