The assumption is wrong. A server motherboard and CPU draws the same power regardless of what it's doing. Lap-tops and the like are different and you actually pay extra for that design. Most circuts these days are nmos technology. Only in cmos does the power go up with the frequency. Peripheral
Nope. Most are CMOS and the power goes up for both NMOS and CMOS with increasing clock frequency. That may not change your conclusion though.
usage, like disk drives, are also constant since the largest power draw goes to keeping them spinning. The seek mechnics are trivial. Floppy drives and cd-rom drives are different. But, most servers do not keep those spinning constantly. Ergo, for all intents and purposes, servers are a constant power draw. They can be rated.
