HOLD IT RIGHT THERE! Your just like me right now man, like 2 days ago i ordered a very similiar set up. Lu computers, right? Just wait one second, that power supply. Dude i found this out right after i purchased my rig and now im so p***ed off that i didn't know this. Whatever you do, do not order that power supply. Its generic and that means its crap, makes a lot of noise, and can be damaged very easily along with damaging the rest of your set up too. Dude change it right now, get a good quality psu, trust me its one of the most important parts of the pc.
