Does anybody know HD 4850's power consumption when overclocked to 825/2400MHz at 1,33V. Thanks for any replies :).

If we assume stock voltage of 1.15v. Then it should be

110*(825/625)*[(1.33/1.15)^2] ~ 194W

This may be slightly too high because not all of the stock 110w consumption is produced by the gpu (some by the memory and fan).

Thanks for your reply. After reading this I think it should be around 180W. So it's not too bad :).
