Depending what CPU and GPU setup you're running you may be able to get a much better PSU than the rosewill for a lot less
I recommend the EVGA 750 B2
-comes with all the cables you'll ever need
-powers my GTX 980, i7-3930K 6-core, MSI Military class III mobo, HDD and SSD without a hitch.
-Only costs $70 http://goo.gl/7756Cm
