500$ gaming rig

[Roxas2030]

Hi, I tried to make my own build but loads of things that I did not know about came into play. I thought it would be simple but stuff like 1.5v for ram and what not interfered. I was wondering if someone can help me out.

I'm currently looking for a 450-500$ gaming rig.

NO to Diablotek!!! It is a PSU-shaped object which should never be attached to computer components if there is any possibility it will be connected to an A/C power source at the same time. Consumer fluff <> competent technical reviews; both jonnyguru and HardwareSecrets have reviewed a few Diablotek models and found them to be overrated GARBAGE.
A quality modern PSU has full range active PFC (no little voltage switch) and some level of 80+ certification for efficiency. On a budget, the Antec Earthwatts and Corsair Builder series of PSUs can usually be found for good prices.
