Hi Jim, High-power video card? Multiple processors? Maybe multiple disk drives (RAID)? All these factors certainly play a role. For instance, my server has on-board graphics which contributes to low consumption. High-end graphics cards consume a lot of energy. I don't have personal measurements but I guess it could be in the 50-100 W range. - Multiple processors also draw much energy. I was surprised that even the load of a single processor influences consumption. I have a notebook with a Pentium 4 Mobile processor. With little load the total notebook power usage is 30 W, at 100% CPU load it rises to 50 W. Current high-end single-core CPUs go beyond 100 W. Hard disk drives don't need that much, in the 10-20 W range per disk, but in a RAID array it adds up.
