JohnHank21 :
you might wanna get a 750w psu but a 550w will work fine.
Nope, that is entirely unnecessary. His rig without overclocking won't reach 300W. With overclocking, it should be around 400W. With that, gaming load is always lower, and the 550 G2 will have efficiency near the sweet spot for his system. A 750W unit is counter-productive because it costs more and is less efficient, so it's all just losing money.
