Energy efficient GPU

I'm building a new PC, which is going quite well and not actually why I'm asking.

My question is actually about how to make my old PC a bit more environmentally friendly as a home server. It was a gaming system, so it doesn't have any on-board graphics options (and my current GPU is going into the new machine) so I'm going to buy a cheap GPU for the old system. Any recommendations of PCI E video cards that use very little power? Most of the time this thing isn't even going to be hooked up to a display at all...

Thanks for any help and/or suggestions.

    from the looks of the chart I would get the nvidia 7300LE
  2. The HD4650 uses 40W of power, as far as I know. Is $50.
  3. Yeah, for minimal display requirements, I second the 4350. All of the low ATI 4000's are very power efficient, but for what you descirbe I see no need to go above the minimum (in cost and power).

    Sapphire 4350 1gb DDR2 $39.99.... cheap.



    +1 for the 4350
  5. Thanks very much for all your answers. I'm going with the Sapphire 4350 suggestions, especially since there's a fanless option, but I'm giving the best answer to nitrous simply because that chart is such an awesome resource, and I didn't manage to find it despite all kinds of google effort :)
  6. That is an awesome chart. Nice find!
