It won't like an Overclock at all with this ,Corsair CX 500W 80+ Bronze Certified Semi-Modular ATX Power Supply

Tier Four
Built down to a low price. Not exactly the most stable units ever created. Very basic safety circuitry or even thin gauge wiring used. Not for gaming rigs or overclocking systems of any kind. Avoid unless your budget dictates your choice.
