#1 | | Golden Member | | GPU: 4850 AC ACC S1 Rev.2 | | Radeon HD 4780 1024mb - power consumption is there a way (tweak) to lower the power consumtion for this card when in IDLE? (150W for idle is not little, but i expect this card to arrive next week  )
greetings
PS: yeah, finally i get it (but still not for the price of 170, but they offered me a price drop of 55 euro -> 230euro instead of 285) |

But then again, I'm sure you understand that this card is high-end and that it is to be expected that it'll consume a lot of power.

#4 | | Golden Member | | GPU: 4850 AC ACC S1 Rev.2 | | will try when it arrived! thanks!
@imodintel, i know that it is highend, and that does not mean anything about idle power consumption 
my monitor is high end too, and consumes 1W in IDLE/powersave |

#6 | | Dedicated Member | | RAM: GEiL 4GB DDR3/1600 CL8 | | | PSU: Coolermaster R P 850W | | I underclocked mine 4870 using ATI Tray Tools to 250/300 (GPU/MEM) and 1.089V in 2D, power drain down to 14.7A (or 14.9 - don't remember exactly) from stock 2D 20.1A (according to the GPU-Z), also temps down to ~40 C at idle in 2D. |
