Overclocking and Power consumption

post #1 of 3
Thread Starter 
I've ordered an i7-3750k, and if i can i will be overclocking it.
But i wonder, does overclocking without raising the voltage increase the power consumption even the slighest bit?
I wish to keep it at 77W TDP, but a simple overclock would be nice.

Also, is there any way to calculate like a formula on the power consumption of a processor?

Overclocking does increase power, but without over-volting it your power increase will be small. I am going to take a educated guess, and say overclock without over-volting would be a 5% or so increase.

The load on your processor has a MUCH bigger effect on wattage than bumping the clock speed up a tiny bit.

The formula for the power of anything is Power (in watts) = Volts * Amps. It's easy to measure volts...but i am not sure how you would measure amps on the processor.

Honestly, if you really wanted to know, you could by a "Kill A Watt Electricity Usage Monitor" for like $15. This way you could measure any changes in wattage cause by overclocking (assuming you provided a constant load).

awesum, thank you very much.
I never would have tought the power consumption would rise when just OCing without raising the voltage.
