When buying a PSU and overclocking a system, what is a good wattage overhead to have? I am using a system with a 6300 and 7970, I currently have a 750w psu and I want to grab a 600w psu. 500 is the minimum wattage needed to power the system stably. Is 600w good for overclocking this system, and what is a good rule of thumb when getting a PSU while overclocking?

Depends on the system, but an average system with 1 GPU and a few hard drives will overclock well on a 500 watts or higher.

A 2 way SLI system with a few hard drives will do fine with 700 watts or higher.

The reason for the downgrade is to save money. If I am not going to use 50% of my 750watts, why keep wasting money on energy. I know it's not much, but it's something. Plus I think my PSU is giving out bad power

The 'something' is negligible.

Why do you think that? What psu do you have?

Thermal and voltage sensors giving out false readings. This has happened on more than one motherboard too

Just because it is a 750W psu doesn't mean it is constantly drawing 750W of power. You aren't wasting money (maybe a tiny amount due to efficiencies) due to having a 750W. Keep the psu you have.
