I hope you installed everything properly too. If you need help let me know. Personally I like seasonic power supplies. Nice build btw. Although you kinda screwed yourself on the CPU. Bulldozer chips aren't doing so hot. Perhaps microsoft will release another "Fix" that actually fixes the performance problems. We shall see. Nice build anyways.As for HDD, should've recycled the one in the current PC and spend the money you spent on a 2tb WD black drive on a 128GB SSD. but meh.
Not sure I'm fond of the CPU cooler, Im quite fond of my h80
