With the lower end intel processor and the relatively small HDD I'd give it a 6/10. Don't let anone knock your PSU. After all it's better to have it and not need it than the other way around.
No one is knocking anything. But when factoring in a rating between 1 and 10 (a rating he asked for, mind you), one would have to be a colossal moron to overlook the fact that his PSU isn't even close to being efficient for his particular build.
