Overclocking core voltage power cost

Just overclocked my R9 280 from i believe 940Mhz to 1000Mhz and was wondering how much more power draw this would require from my PSU (approximate), without changing voltage settings. I mean, it doesn't make sense to get more performance without needing more power, so im assuming there will be more required. But im also not increasing voltage, so would the power increase be marginal? or significant? thanks for any help.

 

ah and it looks like i made an error in the title. Im not changing the voltage, im changing the core clock.
