I'm curious if anyone has data on sources of power draws on a typical server computer. On an AMD single dual core processor system that we start up inan energy saving mode at 1.8 GHz, we are measuring 350 watts in idle state. No hard drives are installed. The processor itself is specified to run at around 95 watts under load, so the additional 250 watts of energy use surprised me a little. How much of the remaining energy utilization is going to chipsets and how much is going to fans?
