You don't seem to understand much and you're following poor advice... the Extreme Power 550W is a trashy Seventeam unit, and it can't deliver 550W(it burned below full load during the HS review).. while the Elite Power you already have is not much better, it can at least deliver it's rated output while keeping regulation in check, and Gabe @ Hardware Secrets managed to overload it to about 420W where it gracefully shut down, showing that the implemented protections work... now, the unit returns appalling efficiency figures(73% at full load), but offers far better electrical performance than the Extreme Power 550W, and it is enough for you system...
You're throwing money away with that Extreme Power 550 unit.
